Title: MH370 missing
Post by: David Martin on 10 March, 2014, 09:56:25 am
My parents came through Kuala Lumpur airport just before the plane went missing. Curiously this was the only airport security that my father's metal knee did not set off the alarms.

 <tinfoilhat>That does make you wonder whether screening had been disabled for a while to allow something to be taken on board</tinfolhat>

My father, a metallurgist and aero engine expert, who has been involved in testing and crash investigation, regards this incident as very odd.  From someone with such a wealth of experience in this area, I take that to mean this is very very odd indeed.

It's not likely to be another Comet incident with the plane spontaneous disintegrating mid air. If 777s were prone to that it would have happened already as they have been in service for a long time now and flown millions of miles. Looks like terrorism or pilot error (like Air France 447). Must be heart breaking for friends and relatives who are just waiting.

The signs point to terrorism. Folk travelling on fake passports. Lax security. High altitude explosion.

Weird that no ones claimed it though.
The passport thing could be a red herring as it seems when an Air India flight crashed in 2010 they found that 10 of the passengers were travelling on false or stolen passports but that crash wasn't terrorism.

What surprises me looking at the projected route is that it was ever off radar. I would have thought that all of that route would have been covered by military radar at least but apparently not.

Experts have expressed surprise that the authorities involved haven't requested radar records from any military vessels in the area.

I suspect plain incompetence explains that.

The passports used that were stolen were stolen years ago, and were on Interpol records as such. That may - or more likely, may not - have some relevance. Terrorism is one of many equally remote possibilities; if terrorism, why a Malaysian aeroplane? Why no claim? In general, terrorism events have the purpose of publicising the terrorists' cause, and the choice of terror act has some logical link to that cause. There are disgruntled people in Malaysia, but there are anywhere. Disgruntled enough to bring down an aeroplane? Perhaps it's related to the recent atrocities in China - but then why not a Chinese aircraft?

There have been instances of aircraft disintegrating in flight without terrorism being involved - the two most recently famous being the TWA Boeing 747 in 1996 that exploded over the Atlantic near New York and the Air France A330 that crashed into the South Atlantic in 2009. It took four years to determine ( and then arguably not conclusively) the cause of the TWA accident, and three years to get the final report on AF447 (two years just to find the 'black boxes').

A question that will be prevalent in the investigators' minds will be why, in this age of interconnected everything, the datalinking between the aircraft and the ground wasn't fast, detailed, or robust enough to show what happened, even if they could not show why. There should be no need for 'black boxes' these days. All modern aircraft are capable of datalinking their flight and system details to their operators to some degree - that's how flight status websites work, using the public part of that data.

So, yes, this is odd. And there should be much more known about it than there is. However, even when the black boxes are found and the information therein is decoded, it'll likely be quite some time before a comprehensive report is available.

I heard on the news this evening that the travel agent who sold the tickets to the two criminals on stolen passports has said that they weren't bothered which flight they got, just the cheapest ones to Europe (or roughly the right part of Europe anyway). If you were going to blow up a plane, I think you'd decide which one first.

My money's on pilot suicide. It's been hushed up before.

Disagree. If you aren't intending to get out of a plane, it matters not where it goes.
It does seem significant to me that the two chaps with stolen passports seemed to be in this together.
Pilots don't work alone and planes don't just drop 6 miles so I don't buy the pilot suicide line.
But this is all speculation.

The dodgy passports thing doesn't exactly say much about how effective pre-boarding controls are in that part of the world - two Asian guys rock up to passport control and present documents with very European names, you'd think someone would go "hang on a second, what's wrong with this picture?"

According to Interpol, it appears that they weren't the only ones on that flight:

http://uk.reuters.com/article/2014/03/09/uk-malaysia-crash-interpol-idUKBREA280LE20140309

And it seems to be a pretty routine activity:

http://uk.reuters.com/article/2014/03/10/uk-malaysiaairlines-flight-idUKBREA2701C20140310

Quote
A European diplomat in Kuala Lumpur cautioned that the Malaysian capital was an Asian hub for illegal migrants, many of whom used false documents and complex routes including via Beijing or West Africa to reach a final destination in Europe.

"You shouldn't automatically think that the fact there were two people on the plane with false passports had anything to do with the disappearance of the plane," the diplomat said.

"The more you know about the role of Kuala Lumpur in this chain, the more doubtful you are of the chances of a linkage."

A Thai travel agent who arranged the tickets for the two passengers using the stolen passports said she had booked them on the flight via Beijing because they were the cheapest tickets, the Financial Times reported.

The travel agent in the resort of Pattaya said an Iranian business contact she knew only as "Mr Ali" had asked her to book tickets for the two men on March 1.

She had initially booked them on other airlines but those reservations expired and on March 6, Mr Ali had asked her to book them again. She told the newspaper she did not think Mr Ali, who paid her in cash and booked tickets with her regularly, was linked to terrorism.

Yeah, very far fetched. When people do a Reggie Perrin, they tend not to drag an entire planeload of other people into it. And I don't believe you can open the doors if the cabin air pressure is greater than outside.

My thoughts exactly! The only one that could reach up that far!

As far as the parachutes theory goes, it's a non-starter, for a start there are non available on commercial flights.

Secondly, you open the door/blow a hole in the side of the plane you are going out of that hole so fast you'll probably be knocked unconscious so pulling the cord wouldn't be anywhere in your (very short) future.

I agree with others, there is too many unknowns with this, but that does not, necessarily, mean that something nasty is afoot, it might just be general incompetence!

Massive, system electrical failure.

No power --> no signals

No power --> no control

Plane glides down to the sea, cause the pilots are doing their best with what control they have. Doesn't hit very hard, so not a major breakup, no oil slick to speak of, comparatively little debris. However I'd expect some sort of EPRIB system to be activated - seems odd that nothing has been detected.

To be honest, having flown probably a gazillion times over the years (I've never counted, but I've done more air miles than most aubergines), I'm surprised by the lack of problems. It's not like you can get out and give the plane a kick if there's a problem. Given the unreliability of the average home computer, or even bicycle, that says something about the reliability of airplanes and the processes that keep them in the air. It something mechanically or electronically calamitously fails at 10,000 metres there's not a lot of places to go other than down. Gravity is non-negotiable. I'm pretty sure no one wants to be left standing on the runway wondering where the spare bolt they have in hand was supposed to go.

But accidents do happen. Nothing is 100%.

I too am a bit shocked and surprised that in this era of connectivity, when Airbuses probably have their own Facebook pages and the NSA knows better than I do where I left my iPhone, that a plane could be so easily misplaced.

It has happened before - Egyptair. The captain (I think) waited till the First Officer was out of the flight deck, then locked him out, then stuck the aeroplane on its nose and hit the ground going very fast indeed. Somewhat unconventional, but effective - if very selfish.

In the panoply of far-fetched theories and cunning plans, this is the best I've heard so far! Departing an airliner in flight with the intention of descending by parachute is all but impossible, unless you're a Hollywood film director. 10/10 for imagination, Ben, but Nil Points for practicability.

Extremely unlikely. While nothing is impossible, the design of modern aircraft systems includes remarkable levels of redundancy. The 777 is 'fly-by-wire', but that doesn't mean that without electrical systems it can't fly. It has a degree of mechanical back-up which affords a fairly basic level of control. Even if all generation capability was lost (engine driven generators, hydraulic-driven generators, ram-air generators* - highly unlikely, but possible) the aircraft batteries will give sufficient power for about 30 minutes of radio and flight control use.

Right now, it seems they've decided they may have been looking in the wrong place. I've no idea why they've come to that conclusion; I thought they had radar and comms up to not far short of where and when it is believed to have disappeared. However, I'm pretty sure it won't be long before they find it one way or another. Once they do, the business of finding out what happened will begin in earnest.



*I'm not a Boeing man these days, and I've never flown the 777, but the aeroplane will have some or all of these, and more than one of most of them.
Title: Re: MH370 missing

I actually meant the sort of electrical failure that destroys all electrical equipment. Burns out wiring, explodes batteries and fries silicon.

Modern aircraft aren't vulnerable to lightning strikes in that way, so it seems incredibly unlikely. But then so does the sudden disappearance of a modern aircraft, without distress signal or something.

Yes, whatever it was was a catastrophic event, which could be natural or man-made. I'm not aware that any significant weather was reported in the vicinity, so the natural causes seem unlikely. But who knows? It's not easy to hide a 200ft long and wide, 300-tonne aircraft, but did anyone check the hangars at KL?

Unlikely with MH370 though at cruise altitude and not near a conflict zone so an accidental missile incident is unlikely. It would have to be a missile launched from a military plane or ship, your not going to get it with a shoulder launched SAM.
It could have been very unlucky and been hit by an ICBM type missile on it way down after test firing. A North Korean one went quite close to a Chinese airliner. However that kind of missile launch would have shown up on military radar.

Flight 714 (http://en.wikipedia.org/wiki/Flight_714)?  The plane was taken over and made a steep dive to get below radar cover.  It was then landed on an uninhabited island using an impromptu landing strip.  It effectively disappeared due to the disabling and replacement of the pilots before they could put out any communication.   OK, not exactly abducted by aliens but they were involved.

If what the Malaysian military are saying is correct, it's no wonder that searching the Gulf of Thailand hasn't worked. This is getting stranger by the day...

Quote
(Reuters) - Malaysia's military believes a jetliner missing for almost four days turned and flew hundreds of kilometres to the west after it last made contact with civilian air traffic control off the country's east coast, a senior officer told Reuters on Tuesday.

In one of the most baffling mysteries in recent aviation history, a massive search operation for the Malaysia Airlines Boeing 777-200ER has so far found no trace of the aircraft or the 239 passengers and crew.

Malaysian authorities have previously said flight MH370 disappeared about an hour after it took off from Kuala Lumpur for the Chinese capital Beijing.

"It changed course after Kota Bharu and took a lower altitude. It made it into the Malacca Strait," the senior military officer, who has been briefed on investigations, told Reuters.

That would appear to rule out sudden catastrophic mechanical failure, as it would mean the plane flew around 500 km (350 miles) at least after its last contact with air traffic control, although its transponder and other tracking systems were off.

A non-military source familiar with the investigations said the report was one of several theories and was being checked.

Title: Re: MH370 missing
Post by: TimC on 11 March, 2014, 02:05:14 pm
There are now suggestions that the aircraft switched off all transmitters and descended below radar cover while turning back toward Malaysia. While the illegal passport holders have been largely exonerated of any terrorist connection, this profile (if verified) strongly suggests a hijack. However, it's not possible (in my aircraft at least) to entirely disable its data links with the ground, so there are still many, many questions.

There are a number of pilot-controlled transmitters - 2 or 3 VHF radios, 2 HF radios, 2 Satcom radios, a transponder with 2 transmitters. All of these can be turned off from the flight deck. However, the aircraft will have a number of other automated engineering datalinks with the ground which generally can't be turned off, and may have also had ADS (Automated Dependent Surveillance) which is a direct datalink to ATC available in many parts of the world. There may also have been cabin telephone/cellphone/Internet systems which aren't directly controlled from the flight deck, but may be turned off elsewhere in the aircraft. That's an awful lot of communications to neutralise!

That is a lot of data transmission.

I'm curious about the lack of radar record.  It's a contested bit of sea, so I'd imagine that there are several military systems covering the area.  And, if it crossed the country again, how come that was not picked up?  I can imagine it might be missed by civilian radar, but a large area of the country not covered by military radar seems suspicious.

There's the rub, because the ACARS transmissions apparently stopped after the aircraft disappeared from ATC radar, which is why everyone thought that there had been a catastrophic failure over the Gulf of Thailand (contrast with the Air France incident, where ACARS was still transmitting during the plane's post-stall descent).

I've done a fair bit of military flying over Malaysia, though not for 20 years or so. Back then, military radar was pretty sparse - and almost none of it was directed inland. Unlike UK (at the time), there was no military ATC radar as far as I remember, just some air-defence radars pointing offshore and local radars at the few military airfields. Area radar services (civilian ATC) weren't comprehensive. But I'm sure much has changed since the '90s, and datalinking has removed much of the necessity and demand for complex and expensive radar systems in remote areas. Ironically, it may now be easier to disappear than it used to be, if you can actually find a way to disable all datalinks!
Title: Re: MH370 missing
Post by: clarion on 11 March, 2014, 02:31:59 pm
I would have thought there was at least coastal radar checking for incursions.  Maybe I'm overoptimistic.

Diabling datalinks would imply a more complex incident, involving people not on the plane as well.

In the old analogue days (9/11 was still in that period), it was possible to use a cellphone in the air up to about 2-3000ft. Not in the digital age, unless the aircraft carries its own satcom-linked cell. Digital cellphones moving at 180mph+ seem to confuse the system, and, before the days of onboard cells and internet, I could only get a digital phone connection on the ground (by accident, of course!).

Its the hand off between cell towers that gets confused. It wasn't designed for something travelling that fast. Plus from height the signal is received almost simultaneously at several towers at once so the cell phone network doesn't know which cell to use for the call.

How mobile comms on aircraft work from an EEC document:

Facts about Mobile Communications On-board Aircraft (MCA) technology

Although still in its infancy, MCA is a growing industry, with data traffic increasing by over 300% between 2011 & 2012.

MCA is identical to normal mobile roaming in that passengers are billed through their service provider. The tariffs applied usually correspond to "Roaming: rest of the world" prices. Wi-Fi is also used for MCA but is not subject to specific rules because its low power does not pose interference risk with ground-based radio services.

MCA does not cover the communication between the aircraft and the ground which is currently provided by satellite-based systems. New satellites should allow ten times greater capacity than what is available today.

Some European stakeholders are working on introducing a new "Direct air to ground" (DA2G) broadband technology, which would bypass satellites.

How do MCA systems work?

The signal is received by an antenna on board the aircraft and sent to the ground network via a satellite connection. The signal is limited in power to ensure it does not interference with other communications.

The system is based on three main parts: the mobile terminals, the Network Control Unit, and the aircraft base station.

    ·Mobile terminals on aircraft: passengers increasingly wish to use their 3G or 4G mobile devices (smartphones, tablets, laptops etc.) on board aircraft to transfer data; the amount of data transferred on board already exceeds voice data.

    ·the Network Control Unit (NCU): is mounted on board the aircraft and is a kind of jammer which prevents mobile terminals connecting to, and interfering with ground-based systems, and ensure they connect only to an Aircraft Base Station (see below)

    ·Aircraft Base Station: the antenna to which mobile terminals connect; it takes the form of a cable running along the ceiling of the cabin.

Mr R got back a a week in Lanzarote on Sunday.  He'd been out there with his sister and a friend, Kim.  Mr R and Kim were flying back to Manchester - his sister was flying back to Bristol.

His sister's flight left earlier than his.  It wasn't until he tried to check in about half an hour after she had that he realised she had his passport and he had hers.  Somehow, despite the very obvious differences and the fact they don't look alike, she'd managed to check in with his passport and get through security.

He had to phone her to come and meet him at security to swap passports.

Another possibility, probably fairly far fetched, but still, is that everyone on board, including the pilots, was poisoned, by the same thing?
What if there was carbon monoxide or something?

Carbon monoxide isn't known for turning off electronics.

Maybe they weren't turned off?
The plane was perhaps assumed to be flying normally until it hit the sea?

Edit: possibly easy to eliminate but if the pilot had slumped forward onto the joystick could it have descended faster than otherwise?

The aeroplane has apparently been tracked crossing the Malaysian peninsula from east to west following the point at which all transmissions - manual and automatic - ceased. It's conceivable that, for instance, the aircraft collided with another unrecorded aircraft, causing the death of the pilots and the loss of all electronic communications yet the aeroplane remained sufficiently structurally intact to glide uncontrolled to a crash site far from the point of collision. Conceivable, but very unlikely. EMP, as discussed earlier, is also conceivable but unlikely. Aircraft are protected against stuff like lightning strikes; a larger EMP event than that would likely have been detected remotely.

All that said, the field of the unlikely is looking more and more likely to contain the answer!

But they were both valid passports. Security would have swiped them and been told they were genuine, not reported missing or stolen, holder not a wanted list, etc. Completely different from using a passport reported stolen a couple of years ago. Having said that, I don't think the stolen passports are anything to do with it. There are a hundred and one reasons for using a stolen Western passport and being an Iranian desperate to settle in Europe seems a likely one.

What about an EMP device on the plane?  We know that stuff carried in the hold is subject to less than rigorous inspection - and if someone wanted to test a device, somewhere like Malaysia would be the place to load it.

I presume they're supposed to but they often don't seem to - which obviously doesn't mean they can't do it quickly and discreetly through practice and training. Unfortunately we don't know what would have happened if Mr R had tried to use his sister's passport. My impression is the rigour of passport security varies enormously from place to place and probably operative to operative within each place - you can leave the UK without any checks at all (though probably not from an airport).

What's the glide ratio of an airliner? I don't know, let say 10.

Starting from 10km altitude, without power the plane would glide for 100km and the plane has been spotted by radar a long way off course. Presumably the plane was either being "flown" or at least the engines were still providing some thrust for some time after the first "incident".

May be a borked attempt to divert the plane?

Marine traffic in the Malacca straits is more important than in the English channel, so presumably somebody would have spotted an airliner going down?

It's getting to the point where we'll have to start putting posters up on lamp posts asking people to check their sheds and garages. Possibly the world is bigger than the internet had led us to believe. Damnit, those cryptozoologists might be right. I was once chased by a Jersey Devil. Or I might have been drunk and it could have been a raccoon.

Years ago, my identity was stolen by svelte guy who continued to travel under my name and with my passport. That chap was rightly and regularly apprehended and forced to wait with the irregularly documented foreigners in the white room of shame. I figure I'm going to get the same shit when I check in for the afterlife. Is this you? Are you sure? I'm very sure. Hurry up with the damnation and hellfire, I have marshmallows to toast.

I eventually had to get a new passport.

Anyway, it was a good test of who did and didn't check the picture:

Americans: usually yes, line-up for the Git-mo express over there, sir
French: they never get past my name, which isn't Harry
Germans: long suspicious looks as they tried to imagine what a man would look like if he wasn't mostly bratwurst
Brits: usually ended up with three people looking at passport, then me, then passport, then me.
Africa, Middle-East, Far-East: no, no, no, probably because us whiteys all look the same to them (actually, psychologically, that's probably true)
Israel: surprisingly not, probably too busy doing background checks on my grandparents and surveilling my cats
Canada: they thought I had cancer, then was Michael Stipe. Or possibly Moby. All very sensitively dealt with.

The great thing about the internet is that lots of people who ordinarily would struggle to build a paper plane are suddenly experts on the real thing. I know absolutely nothing about airplanes. I think magic keeps them in the air.

There's been a case of the pilots on an airliner losing being asphyxiated. As TimC says, it doesn't turn off the electronics.

That one flew on autopilot until it ran out of fuel, watched by Greek AF fighters which had been sent up to see why it was ignoring ATC. Saw through windows, the co-pilot slumped in his seat, pilot's seat empty, oxygen masks hanging down. A flight attendant (with a commercial licence, but not qualified on that type) tried to take the controls (seen by the fighter crews), but failed to achieve anything before it was too late.

Its the hand off between cell towers that gets confused. It wasn't designed for something travelling that fast. Plus from height the signal is received almost simultaneously at several towers at once so the cell phone network doesn't know which cell to use for the call.
Which makes it hard to distinguish between a phone overhead, & multiple identical (i.e. fraudulent) phones. Two or more identical phones trying to connect to the network at the same time triggers the fraud catchers.

The chief of the Malaysian Air Force is now pouring cold water on the idea that the aircraft was tracked across to the Straits of Malacca. The search operation is being scaled down somewhat, and there seems to be confusion all around about what to do next. They are investigating a sighting from three hundred kilometres away from where the aircraft was last seen on radar; a NZ oil rig worker reports seeing some kind of burning in the sky at about the right time.

Back in Baader-Meinhof days I crossed the border at Saarbrücken with customs plates on the car: the German border guards decided to do a thorough check and had me turn out onto an apron to the side of the main road.  While they were checking, a couple of French guards with submachine guns moved down to cover me & the car from the far side, whereupon the most colossal barney erupted between them and the Germans. The French eventually moved off to one side a bit, rather sheepishly.

Turned out that the German guards didn't appreciate being in a straight line with a couple of French submachine guns.

A 777 isn't a Cessna Cub, you cant land it in a field you need about a mile of nice smooth tarmac or concrete to set one down on.

On a modern airliner such as the 777, is it possible for the pilot to turn off all transponder systems?

That question was asked and answered upthread:

There are a number of pilot-controlled transmitters - 2 or 3 VHF radios, 2 HF radios, 2 Satcom radios, a transponder with 2 transmitters. All of these can be turned off from the flight deck. However, the aircraft will have a number of other automated engineering datalinks with the ground which generally can't be turned off, and may have also had ADS (Automated Dependent Surveillance) which is a direct datalink to ATC available in many parts of the world. There may also have been cabin telephone/cellphone/Internet systems which aren't directly controlled from the flight deck, but may be turned off elsewhere in the aircraft. That's an awful lot of communications to neutralise!

Who would have fired this missile? From where? Who (other than governments) in the area has large ground-to-air missiles with the range and speed to take out a target at 35,000ft? What political reasons would there be for such a strike?

Missiles do not generally destroy large targets, they incapacitate them to the point that they fall apart. Debris would be scattered over a very wide area and, given that there's no shooting war going on between Malaysia and Vietnam, the event would likely have been noticed (not least by American and Chinese surveillance satellites) and commented on by someone.

At the moment, I'm wondering if they hit another, un-notified, aircraft. Which could have had the same effect, of course, but which doesn't need premeditated murderous intent.

Anyway, I'm just curious to know what effect it has had on the wider industry at this stage?

Incompetence. Not admitted to due to reluctance to admit to said incompetence.

That does make more sense than a random missile - at 35 000 feet and not posted as missing, I guess it would have to be a military aircraft. Which begs the question; why hasn't someone owned up to it?

One was a misidentification at a time of a de-facto shooting war, the other an accident well outside the range capabilities of the missile (but probably caused by a collision with parts of the missile in its descent after running out of fuel). A degree of incompetence was implicit in both cases, but neither event went unnoticed! In fact, the Siberian shoot-down was detected by the CIA pretty much instantly, and the Iran Air shoot-down was a deliberate act and seen by many agencies in the area.

*On checking my facts, the Iran Air flight was only at 14,000ft - very low for a jet airliner. So the only high-level ground-to-air missile shoot-down of an airliner is the Siberian Air one. There have been several shot down by fighters, but these have all been deliberate acts where the facts were more or less easily established.

Ben, are you seriously suggesting that the pilot of a major airliner wouldn't know:
A) How much fuel he needed to fly from point a to point b
B) What sort of runway he needed.

well he probably knew it isn't SUPPOSED to land on anything other than a runway but he might have thought it possible albeit a bit bumpy.
I don't know.it probably didn't, but it did start heading west, and like they're saying, when you've eliminated the probable, you have to look to the improbable.

Yes. Fired from a Russian SU-15 fighter. Being AAMs (air-to-air missiles), they don't come under the category of missiles fired from the ground. Which was the point of my post - in which I also mentioned airliners shot down by fighters.

Tim, RE the collision theory. If an aircraft were flying an unnotified flight through the area would they not choose a flight level that isn't used by the commercial traffic? Say the 29,500 that the aircraft crossing the Malay peninsular is supposed to have been at? Or maybe it was transiting between two flight levels and got very unlucky?

We were talking about airliners being shot down by surface-to-air missiles. As I explained, airliners shot down by fighters are really a quite different category because the shootdown must be deliberate, and a significant number of people will know about it, whereas it's conceivable that a surface-to-air missile strike may happen by accident (as in the Ukrainian case), and may not be known about - at least initially. The lack of a shooting war or military exercises in the area makes either possiblity rather unlikely, however - and I doubt anyone other than Singapore in that area has SAMs capable of downing a plane at 35,000ft.

There have been far more mid-air collisions involving airliners than shootdowns, and several have involved aircraft flying outside controlled airspace. I'm not sure of the status of the airspace that MH370 was flying in, but it's likely to be fairly open airspace in which anyone can fly. There are many aircraft that can fly at that kind of altitude, and (for example) major-league drugs smugglers do use executive jets to move their products quickly and secretly, and will take great care not to inform air traffic control where they are or where they're going. I don't know whether there is a lot of drugs traffic in that area, but I'm pretty sure that the possibility is being investigated.

You may recall the event in Brazil in 2006 in which an executive jet collided with a 737, which crashed killing all on board. The executive jet landed safely.

A 777 isn't a Cessna Cub, you cant land it in a field you need about a mile of nice smooth tarmac or concrete to set one down on.
Plus they had nowhere near enough fuel to make it anywhere near a western country.

Oh I don't know they might have been intending to land half way in Kazakhstan somewhere. They might already have done!
In fact Kazakhstan would be an ideal stop off to be honest, it's big and most areas probably pretty remote (lots of nice flat fields) and it's pretty much exactly half way.

The latest from Aviation Week magazine's website:

Quote
Malaysian Airlines said today reports that the missing MH370’s Aircraft Communications Addressing and Reporting System (ACARS) sent transmissions for several hours after the 777-200 flight vanished from radar are false.

“Engine data transmission reports are inaccurate,” Malaysian Minister of Defense & (Acting) Minister of Transport Hishammuddin Hussein said at a press conference. “Both Boeing and Rolls-Royce have told us they did not get any ACARS transmissions after 1:07 a.m. last Saturday.”

That said, the WSJ corrected their earlier story, so now it's claimed that satellites picked up "pings" from the aircraft, as per PeteB99's post.

Corrections & Amplifications
U.S. investigators suspect Malaysia Airlines Flight 370 flew for hours past the time it reached its last confirmed location, based on an analysis of signals sent through the plane's satellite-communication link designed to automatically transmit the status of onboard systems, according to people familiar with the matter. An earlier version of this article incorrectly said investigators based their suspicions on signals from monitoring systems embedded in the plane's Rolls-Royce PLC engines and described that process."

Reuters are reporting on the "pings" theory as follows:

Quote
Satellites picked up faint electronic pulses from Malaysia Airlines Flight 370 after it went missing on Saturday, but the signals gave no information about where the stray jet was heading and little else about its fate, two sources close to the investigation said on Thursday.

But the "pings" indicated that the aircraft's maintenance troubleshooting systems were switched on and ready to communicate with satellites, showing the aircraft, with 239 people on board, was at least capable of communicating after the jet lost touch with Malaysian air traffic controllers.

The system transmits such pings about once an hour, according to the sources, who said five or six were heard. However, the pings alone are not proof that the plane was in the air or on the ground, the sources said.

An international search is under way over a vast area in the Gulf of Thailand, the Andaman Sea and on both sides of the Malay Peninsula. The United States, which has sent ships and planes, said the area may be expanding into the Indian Ocean.

"It's my understanding that based on some new information that's not necessarily conclusive - but new information - an additional search area may be opened in the Indian Ocean," White House spokesman Jay Carney told reporters in Washington.

<snip>

LITTLE FRESH LIGHT

The new information shed little light on the mystery of what happened to the plane, whether there was a technical failure, a hijacking or another kind of incident on board after it took off from Kuala Lumpur en route to Beijing.

While the troubleshooting systems were functioning, no data links were opened, the sources said, because the companies involved had not subscribed to that level of service from the satellite operator, the sources said.

Boeing Co, which made the missing 777 airliner, and Rolls-Royce, which supplied its Trent engines, declined to comment.

They have been caught out without a properly developed process for dealing with this sort of thing. Though aircraft losses are rare, airlines (and governments) normally have pretty robust PR departments with procedures for dealing with uncomfortable situations. That seems to have been missing here. It also appears that no-one picked up the job of coordinating and controlling the search, nor of being a centralised point of information. Thus we have rumour and speculation going crazy, and seemingly random searches by disparate countries and organisations.

I'm sure that by now most of these things have been or are being addressed, but it's been a demonstration of how not to do it! However, the complete disappearance of an aircraft is not an easy thing to deal with so I think we can cut the Malaysians some slack.

Both good points, Spesh.

But, looking at the passenger roster the only countries helping are the ones with passengers on the plane, mainly China.

If there are any RN assets in the Indian Ocean, they will most likely to be on anti-piracy duties off the coast of Africa, and given the area that is patrolled, the multinational flotilla deployed there can't spare sending a ship all the way across to the south-east Asian side of the ocean.

The island they live on is otherwise uninhabited and under official protection. The perfect place to start a new civilisation!

Interestingly, South Andaman Island (one of the larger islands in the archipelago) possesses an asphalt runway at Port Blair - the airport is under the control of the Indian Navy and only daytime is allowed.

Quote
The airport has a single runway of 3,290 m (10,794 ft) in length, accommodating most narrow-body aircraft, that includes Airbus A320, Airbus A321, Boeing 737, which regularly serve Veer Savarkar airport. An ILS is available for low visibility operations, but pilots are responsible to check with local authorities to verify the system is operational prior to the flight. There is a road across the runway; traffic had to be stopped in order for aircraft to take off, similar to the Gibraltar Airport. Restricted Area Permits for the Andaman and Nicobar Islands are available on entry. Except for the civilian terminal operated by the Airports Authority of India, all other air traffic operations over Port Blair are undertaken by the Indian Navy. The geography makes this a difficult airfield for aircraft, as a hillock at one end means that planes can land or take off only in one direction. Winds change here every six months, so pilots have to either take off or land with strong tail winds.

That said, if a rogue 777 turned up at Port Blair in the middle of the night, you'd think that we might have heard about it by now.

The plane was hi-jacked by the two passengers who boarded using stolen passports. They intended to suicide crash in Hong Kong.
The hi-jackers disabled all comms systems to effectively fly the plane unseen.

Enroute, the crew and other passengers attempted to overpower the hi-jackers. But alas, the hi-jackers detonated  explosives in the hold which broke the plane up.

A New Zealand Oil rigger saw the burning remains of a fuel tank approx. 300 miles east of the ‘disappearance site’, which was on the flightpath to Hong Kong.

The other remains of the plane are in the South China Sea southeast of the Vietnamese coast.

The Americans are pointing the search toward the west because they and the Malaysians ( and possibly the Vietnamese ) were in partnership to operate a ‘Black-ops’ move to hit China in one of their economic centres, and blame a terrorist organisation for the atrocity, with the aim of causing decline in the Chinese economy.

The Malaysian Authorities are not telling us the truth.

I would guess it's protection of national commercial interests.

Can't have expensive 'mercan planes falling out of the sky.

Speaking of commercial interests, IIRC there was a bit of a catfight between the French air accident investigators, Airbus and Air France after the AF447 crash.

I don't suppose anyone has even considered that the US Government is assisting with the search for MH370 for humanitarian reasons?

Or that there is an industry-wide interest in finding out what the hell happened as soon as possible so that lessons can be learned from the episode?

Both good points, Spesh.

But, looking at the passenger roster the only countries helping are the ones with passengers on the plane, mainly China.

The UK could send help, but hasn't, same with other European countries. Why? Well because they have no commercial or political interest in the tragedy, that's why.

I believe Japan has given assistance without having had passengers aboard.  Remarkable, given relations between China and Japan.

Wall Street Journal are sticking to the story of continued data transmission which locate the aircraft in the Andaman Sea. The US are moving a warship to the area, and have given the Indian authorities directions on where to search. The plot thickens.

That's the other thing I don't quite get -why is America sticking its beak in? What's it got to do with them?

One (or maybe two) of the passengers were 'merkins, that's why.

Plus it's a US built plane, as Wunja says.

As the country of manufacture of the aircraft, the USA has a statutory responsibility to the investigation. They also have the greatest expertise and the greatest resources. They are required to help, and I'm sure they wouldn't dream of withholding whatever assistance they can give.

Until we know what's happened we can't say who does or doesn't have a commercial or political interest.  If the plane was lost because of a catastrophic or technical failure all countries with significant aircraft manufacturing willhave a commerical and political interest.  If the plane was lost due to terrorism or the deliberate actions of the crew/a crew member, then all countries will have a political interest.

Distance. It takes weeks to get a ship from Europe to the south China sea. All the countries that are local to the disappearance are helping as much as they can plus any that have assets within a reasonable range (eg the US).
Rolls Royce have a team assembled to look at the engines once they find the plane.

In an aircraft accident, the country where the crash occurred has primacy in the investigation, followed by the country of registration then the country of manufacture. If a major component made elsewhere is implicated (such as the engines, which are UK-made) then that national authority and manufacturer must assist with all appropriate and relevant information. As in the loss of a ship, all parties who can MUST assist in the search and rescue operation.

Aviation is not like ordinary politics or diplomacy; there are legal requirements of all parties, and the process is led by the priority of saving lives either now or in the future.

Technically, the Malaysians aren't explicitly saying "hijack" - all we know is that someone with the technical nous to try to put a 777 in "stealth mode" has taken the plane off its intended route, and has used known way-points to take the plane off course.

Given that the flight crew cannot be ruled out as the perpetrators of this disappearing act, this could just as easily be the aviation equivalent of barratry as defined under admiralty law:

Quote
In admiralty law, barratry is an act of gross misconduct committed by a master or crew of a vessel which damages the vessel or its cargo. These activities may include desertion, illegal scuttling, theft of the ship or cargo, and committing any actions which may not be in the shipowner's best interests by the master or crew.

Because, as Canardly suggested, the hijacker is "part trained".  That training may have included basic how to evade detection techniques and our hypothetical hijacker knew enough to ensure that emergency beacons were not enabled.  So rather than the pilot switching off beacons it was the hijacker.  Why? I don't know.  Perhaps to prevent an intercept and shoot down by someone's military if the aeroplane was found to be heading somewhere sensitive.

They never felt the need. I would assume that they have the serial number of the engine from which the data comes, and with $lots engines, they know who owns each one, and if they have some information about the engine to give to  the owner, they want the email address of the maintenance department, not the current location.

The airline hadn't bothered subscribing to any services like that. The information coming back was just an hourly signal to prove it was working.

I suspect that GPS receivers will be in the the next version of the engine monitoring equipment. I also suspect that the manufacturers and airline will one day have some tiny airflow powered tracking units fitted, with no electrical connection to the rest of the plane.

It doesn't need to be a cat, or even something capable of dying.  Just a thing that exhibits a macroscopic response to the emission of a particle (the isotope sample, geiger counter and poison gas that are key to the original thought experiment tend to be overlooked in popular culture).

The point is that the box is sealed for a period of time in which there's a 50% chance of an atom in the sample decaying.  During that time, because the box is sealed you have no way of knowing whether an atom has decayed and the geiger counter has triggered the poison and killed the cat, in the same way that you don't know the state of a superposed particle.

That's it.  It's simply a metaphor for understanding states of quantum superposition (and how they represent a state of "can't know" rather than "magic two-contradictory-things-at-the-same-time-ness").

Facts about Mobile Communications On-board Aircraft (MCA) technology

<snipped>

How do MCA systems work?

The signal is received by an antenna on board the aircraft and sent to the ground network via a satellite connection. The signal is limited in power to ensure it does not interference with other communications.

The system is based on three main parts: the mobile terminals, the Network Control Unit, and the aircraft base station.

    ·Mobile terminals on aircraft: passengers increasingly wish to use their 3G or 4G mobile devices (smartphones, tablets, laptops etc.) on board aircraft to transfer data; the amount of data transferred on board already exceeds voice data.

    ·the Network Control Unit (NCU): is mounted on board the aircraft and is a kind of jammer which prevents mobile terminals connecting to, and interfering with ground-based systems, and ensure they connect only to an Aircraft Base Station (see below)

    ·Aircraft Base Station: the antenna to which mobile terminals connect; it takes the form of a cable running along the ceiling of the cabin.

Switch off the relevant satcomms system connected to the Aircraft Base Station, and you don't need to confiscate and switch off all of the passengers' electronic devices.
Title: Re: MH370 missing
Post by: Kim on 16 March, 2014, 01:32:20 pm
Right.  But switch off the base station and the devices will crank up the power and attempt to connect (mostly unsuccessfully) with cells on the ground.  Severing the link while keeping the base station active is going to be relatively subtle.  Of course, all evidence so far indicates someone who knows what they're doing...

Radar 101:

You may have noticed that the reports on MH370 have mentioned primary radar and secondary radar.

Primary radar is what is used to detect, and obtain positional data on, airborne objects. It transmits RF energy, and uses what is reflected back to the receiver to build a picture of what is out there in terms of range and bearing from the radar system. Primary radar does not need to rely on the cooperation of any systems on board an aircraft in order to detect it.

Secondary radar is the civilian version of the Identification Friend or Foe system that the military use. This transmits a pulsed signal which is picked up by a receiver on an aircraft. The transponder then broadcasts a coded signal giving information about the identity of the aircraft, and/or its altitude. This information is tagged alongside the icon representing the aircraft on a radar operator's screen.

Switching off the transponder does not render an aircraft invisible, it merely makes it "unidentified".

http://en.wikipedia.org/wiki/Secondary_surveillance_radar
http://en.wikipedia.org/wiki/Transponder_(aviation)


Quote
Of course I recognise that the countries towards which the aircraft flew may not be so well equipped.

Any radar network is only as good as the equipment (coverage, resistance to countermeasures, etc)and its operators. The latter point is crucial - are radars in operation 24/7, how well trained are the operators, what procedures are in place in the event of an unidentified or unresponsive aircraft being detected?

Because it looked so ordinary and explicable and no one expected such a stunt.

To most people a civil passenger aircraft looks pretty ordinary and it wasn't reported missing until long after it actually was. So whilst it was flying no one was looking out for it as such.

My aviator cousin doesn't rate it as being that difficult to make off with an airliner in that part of the world, especially one belonging to an outfit like Malaysia Airlines!

Look down for a while if you have the opportunity to fly a long distance. Huge swathes of what's underneath are open ocean and sparsely inhabited land. It's a surprise we don't lose more things. If they pointed the jet out to ocean, then it could be anywhere. What is evident is that it didn't land so they probably ran it dry and bellyflopped into the ocean.

I dunno, if they'd come in over land, I'd have expected more radars to have pinged them, plus there's cell towers etc. And they'd need a suitable runway, you can't land a 777 in a field. So they'd need a suitable landing site somewhere very remote. OK, it's possible, but seems less likely than heading out to sea where there's unlikely to be any radars or cell towers. Of course, it would depend on their motivation.

Not heard about the gold, but that sounds rather colourful speculation. I suppose if someone turns up at one of those gold-for-cash places with 10 tonnes of the yellow stuff we'll know.

"Fell off the back of a Boeing, mate."

Yeah, it would require at least three people in separate places - one who knew the gold was going on that plane, one of the crew and one wherever they landed. And I can't think where they might have landed without other people noticing, unless they found a disused military airfield, maybe in the old nuclear testing zone of Kazakhstan. Mmm, this gold is really shiny.

Post by: andrew_s on 16 March, 2014, 09:10:42 pm
I believe the gold theory came from the early report that 5 no-show passengers had been substituted by standby passengers. Since the flight was some 50 passengers short of regular capacity, this led to the question of what heavy cargo could have been carried that would have stopped the standby passengers just being booked straight onto the flight.

The only information released on cargo seems to have been a statement that there was no hazardous cargo (a lithium battery fire had been suggested).

I will be doing it today flying home from China. 13 hours in the air. Of which 10 will be over Nothing At All, most of which will be Russian. It would be very, very easy to lose a plane in that. Sadly, the fact that the world is much more uninhabited than you might think also means that spare 10,000ft runways aren't as usefully placed as they might be if you want to hide a B777.

It's not sure the plane didn't land. They've said it's possible the pings from the engine could have been received when it was on the ground. There's also a theory (or rumour maybe), which I haven't seen in the UK press, that the plane was carrying 10 tons of gold and someone on the ground who knew which plane the gold was on informed one of the crew. If that was the case, you really wouldn't want to crash it. OTOH you then have to find a way to dispose of rather a lot of gold. And 268 other people to, probably, kill.  :(

I dunno, if they'd come in over land, I'd have expected more radars to have pinged them, plus there's cell towers etc. And they'd need a suitable runway, you can't land a 777 in a field.

You can - it just won't take off again...  and you may not be too worried about that.

Latest theory.

20 of the passengers were employees of Freescale Semiconductor, of Austin, Texas.

Freescale Semiconductor was a division of Motorola and supplied equipment for the Apollo missions in the 60s and 70s.
They are owned by Blackstone, who are owned by Jacob Rothschild.

Suggestion is they are a supplier to US Dept of Defence, providing ‘Battlefield electronics’, including ‘Stealth’ technology.

At Freescale Semiconductor, a patent was filed which would be extremely financially lucrative for the partners holding the patent.
The five partners sharing the patent were Freescale Semiconductors and four of the twenty Freescale Semiconductor Engineers on MH370.

Details of these passengers has been removed from the BBC’s webpage since last Friday.

If any of the Patend holders dies, the royalties are share amongst the remaining partners. The only remaining partner now is Freescale Semiconductor.

Unfortunately for the remaining passengers and the persons performing the hi-jacking, they would have had to die too.

The plane is on the Indian Ocean seabed.

You don't think there might have been an easier, quieter, more surgically precise way to bump them off?  With less collateral damage and fall out?

Maybe their details were removed because they weren't on the plane?  Are they missing at all?

An alternative scenario is the 20 Freescale employees, gathered together and with no means to seperate quickly, if killed by a 'Competitive' nation to the US, would put Freescale and the US Dept of Defense's 'stealth technology' back several years.


What's leading me down this avenue is I was curious about 'a Semiconductor company' after reading the BBC's webpage last Friday. I researched and found it was Freescale in Austin, Texas who were part of Motorola, and were suppliers to US Dept Defence.
I checked BBC's page this morning. 'Semiconductor company' and the 20 employees are now not being mentioned.

Why would the Beeb edit out 20 of the passengers off its webpage?

Not really how patents work. The applicant owns the monopoly (in this it would be Freescale) but individuals working for the company would be named as inventors. There would be most likely an agreement in their employment contract regarding payments for anything they invent while working there. And anyway, for a patent to be granted you have to divulge to the world how you do it. That's the deal - you tell us how you do your clever idea and you'll be protected from anybody ripping it off for 20 years.

Maybe he stopped somewhere, you know, to make hamburgers for the passengers and while he was barbecuing those juicy beef patties, his back turned, the plane wandered off.

Or perhaps it was a big gay plane that didn't want to go back to Malaysia.

Perhaps the pilot forgot his toothbrush and made the mistake of stopping in Kurgistryauzanistan to get one. Unfortunately, while it's a great place to be gay, owning or attempting to acquire a toothbrush is very illegal.

Speculation quickly extends to the ridiculous in the absence of hard information, doesn't it? People who otherwise regard themselves as inteligent and discriminating start to believe any half-baked story they can find on the internet, without applying Occam's Razor to it. Some, and there are plenty of examples here, make up their own theory, broadcast it, and wait for it to do the rounds and come back to them exaggerated and 'verified' by the process of repetition.

This is currently a mystery, but the explanation will be logical and understandable even if more than a little unusual.

In the absence of a physical wreck to provide publicly-available clues, however, this has become a detective operation which will probably not be held in the public domain and therefore will give us little or nothing to talk about in a way which illuminates rather than befogs.

I'm happy to explain terminology, or answer questions about equipment or procedures, but I don't want to engage in the kind of wild speculation which is now taking hold. That sort of thing needs damping down, and we have to be patient and let the experts get on with it and come back to us when they have something to say. That could be months or even years away.

This is one case though where there actually has been a conspiracy.
It's possibly a lot more boring and logical than a lot of the conspiracy theories suggest but the plane has obviously been willfully diverted from its original destination by design. WHOSE design, and what their motive is, we don't know, but it hasn't just accidentally got lost.

Please don't tar me with your brush.  The only theory I put forward was based on Tintin and it has yet to be shot down!

You must also consider that had the Malaysians done a bit of lateral thinking instead of jumping to obvious conclusions based on lack of data or ignoring possibilities, the search might have been carried out more effectively and sooner.   As I said earlier, I have ceased to believe anything much now.  It's obvious that there must be people who know something but are keeping very quiet.  The intelligence services of the world must surely be working on that. 

Unfortunately my aviator cousin was, as I guessed he would be, very disparaging about the whole set up in that region and had no trouble accepting the possibility of making away with such an aircraft if you knew how to do it.  Where it would end up is another matter but in that area concealment, if only of wreckage, is possible.  (Also met someone senior from the airside of operations flying Concorde in its heyday, he didn't feel able to put forward theories, either. Which, like this entire episode, was disappointing).

Among other things it is an undoubted embarrassment for the entire civil aviation industry.

Look, the problem is that you know nothing. I know very little, and this is my job. There may have been a conspiracy, Ben, but equally this might have been the work of one person. Neither you or I know, and we can't help the investigation by putting forward theories.

The world is a very large place, and even a Boeing 777 is very small in that context - yet it has the ability to travel up to half way round the world, and do so quite quickly. South East Asia is not Europe or the US; it is not saturated with high-tech surveillance systems and it include relatively little landmass and absolutely enormous stretches of ocean. The assets available to search that enormous area are relatively few, and the most effective are optimised for finding several thousand tonnes of submarine, not a couple of hundred tonnes of an aeroplane that may well be in several bits.

Whether or not there were errors in the hours immediately following the aircraft's disappearance (and of course, the armchair warriors are highly qualified to judge that - in their own opinion), the fact remains that this is not a simple matter of a crash recovery. There are few clues to what happened or why. To establish those facts will either need the aircraft to be found, or conspirators (if there are any) to be discovered and interrogated. If anyone here has information, ideas, or opinions to make that happen more quickly, they should directly contact the Malaysian, US, or Chinese authorities.

No worries, Fuzzy.

The problems I described above are compounded by the fact that the various countries who might be able to contribute information probably don't want to disclose their capabilities - or lack of them. It's not easy for a country to have to admit that an aircraft flew through their airspace and they didn't see it. There are lots of political tensions in the area, and there's no way that, for instance, Myanmar will admit to Malaysia that their air defences are useless. And if the aircraft descended to, say 2000ft, it only needs to be 40 miles off shore (or less overland) to be below the radar horizon, and invisible - and that would be true in Europe, never mind in the remoter parts of Asia.

I'm presuming from TimC's post above that radar (the type that doesn't need any input from the plane) is straight line stuff, so anything below the horizon can't be seen.

People tend to overestimate how far away the horizon is, or to put it another way, how quickly the earth curves out of sight.

Quite a lot, but if you were trying to evade detection but go a long way, you'd only stay low long enough to achieve what you need. The problem with being low is also that you can't go fast compared to what you can achieve at normal cruising levels.

True. Was sailing a boat in very calm conditions and can recall that when I stood up I could see a normal navigation buoy on the horizon; when I sat down it disappeared!  I tried it several times just to check it wasn't an illusion.  It can't have been very far away at all.

Was thinking just that as I left Heathrow yesterday. Looking at a 747 I'd say a 'wheelspan' is about 3 lanes wide. But that's a guess and the pilot would have to be very precise

30m to clear the engine nacelles according  to Boeing

http://www.boeing.com/assets/pdf/commercial/airports/acaps/7772sec4.pdf

You would have to add a fair bit on to that to allow for the fact you aren't going to land exactly mid line and for wind gusts. Then you have to allow for the wingspan of 70m, so no lamposts or trees or high fences. That's a very very wide road.

One of the scariest landing I ever had was in Addis Ababa, shortly after the end to their civil war.  We landed in an Airbus (not sure which one - but it was big) ans the runway still hadn't been completely mended - the pilots were actually swerving the nose gear around some of the larger potholes/craters.

The problem was that people had taken refuge in the airport during the war and had built shacks to within metres of the runway.  The wings were barely clearing some of them and I dread to think what would happen if a tyre had burst...

That was also one of my worst stays in an airport.  We were offloaded only to find that out onward flight to Kinshasa had been cancelled.  We had to spend 24 hrs in Addis Ababa airport which, at that time (and it's scarily long ago now I think back), was a concrete block with an intermittent electrical supply and no water.  And it was hot!

Luckily, I had a firend working at the British embassy in AA who I called.  She came and picked us up and we spent the night at her place - although 'officially' we never left the airport.

It's not the width of the road that's important - it's how deep and strong the road bed would have to be to support the aircraft weight!

Max landing weight for a B777-200ER is 213,180 kg (http://en.wikipedia.org/wiki/Boeing_777#Specifications) - spread across 14 wheels, that's an average of 15,227.14 kg per wheel, although I would imagine that the main gear takes most of the load. Even if the plane is running on fumes by the time it is landed, the ground pressure will still be quite high, several times higher than what a heavy goods vehicle would apply to a normal road surface.

See: http://en.wikipedia.org/wiki/Highway_strip

Put it like this, a B777 trying to land on a normal road will be like a well-built person riding a road bike over a row of water biscuits...

Manhole covers for normal loads are class D400 where the 400 is a load rating, motorways are E600 to accommodate the greater traffic speeds and larger vehicles. Airports are F900 so half as strong again as motorways and more than twice normal roads.

this might have been the work of one person.

Oh come on! Surely you can't seriously believe it's possible to make off with an entire plane on your own.

Yes, Ben, I do. I do it with one other person pretty much every time I go to work. Once I am airborne, I am in a locked flight deck that no-one else can enter unless I allow them. If I killed the other pilot, there is no-one and nothing that could stop me taking that aeroplane wherever I wanted short of being shot down. Which is why that is exactly the sanction that European and US authorities promise if any airliner in their airspace should give any sign that things are not as they should be.

Equally, if the crew's security procedures aren't as thorough as they should be, it is possible that a hijacker could enter the flight deck immediately behind a cabin crew member, lock the door behind him and kill the three crew in there before taking control of the aircraft.

None of this is likely but it is possible and less unlikely than many of the scenarios being proposed.

Tim,

Realistically, there's little chance of successfully putting a B777 down on a road - even the kind of road that in the cold war was reinforced for fighter operations. There might be a few very large motorway-standard roads which are straight for a mile and a half, with no over- or under-passes on which it could be possible, but that kind of road tends to be built to accommodate a large amount of traffic, and the motons might notice a B777 amongst them.

There are a number of disused WW2 (and later) airfields in SE Asia (including Burma) which could accommodate a lightweight B777, at least for a once-only landing, and I would imagine that there are several satellites looking for any evidence of such a landing.

Kind of. It's entirely practicable for a single pilot to operate a modern airliner, but the procedures aren't designed that way; it's a team operation rather than one guy being redundant while the other does the work. For instance, the fact that they believe the copilot made the last transmission would normally indicate that the captain was the operating pilot. But that's convention, and not a requirement.

What's the percentage difference in range of a 777 flying at 2000' as opposed to 30,000' ?

Significant I'd say, based purely on my memory that I managed to get better range out of a Dominie by climbing to 39,000' from 37,000'. As jet engine efficiency increases as temperature decreases and 20,000' is approx -30C (from memory, I may be wrong :)) so relatively warm compared to -52C at its normal cruise of approx 40,000'

Nil points, Paul! ISA is 15C at sea level, reducing by ~2C per 1000'. So FL200 is -15C; and the tropopause (approximately FL370) is about -58C. Above that the atmosphere (at least the part of it that aviation uses) is isothermal.

As for fuel consumption, the fuel flow at 2000ft will be around 6-7 tonnes per hour at the most economical speed - around 220kts. That's not much different from the fuel flow at 35,000ft but the speed over the ground will be around 500kts, so the specific fuel consumption (kg/nm) is much lower. The aircraft would have had around 55 tonnes of fuel at take off, and would have had about 45 remaining at the point it disappeared (I'm basing these numbers on the A330-300, which is a bit lighter and uses a bit less fuel). I believe it flew at around 30,000ft across Malaysia heading west for about an hour - so it now has around 39 tonnes. If it then descended to 2000ft and spent, an hour at that altitude (travelling 220nm in doing so, and leaving 33 tonnes), it could then climb to 10-15,000ft to stay clear of primary radars, and would have been able to fly about another 2000nm. That gives a pretty big circle of uncertainty.

This is what the BBC said:

Quote from: BBC
Another theory circulating is that the plane was taken up to 45,000ft to kill the passengers quickly, former RAF navigator Sean Maffett says. The supposed motive for this might have been primarily to stop the passengers using mobile phones, once the plane descended to a much lower altitude. At 45,000ft, the Boeing 777 is way above its normal operating height. And it is possible to depressurise the cabin, notes Maffett. Oxygen masks would automatically deploy. They would run out after 12-15 minutes. The passengers - as with carbon monoxide poisoning - would slip into unconsciousness and die, he argues. But whoever was in control of the plane would also perish in this scenario, unless they had access to some other form of oxygen supply.
Little has been said about this apparent climb to 45,000ft, or how that information was obtained. If it's genuine and was established by an air-defence height-finding primary radar, the theory above is more or less feasible. They are wrong in at least one crucial aspect - the pilots have a separate underfloor liquid-oxygen supply totally unrelated to the passengers' chemically-generated oxygen, and that pilot oxygen can last for a significant amount of time longer than the passengers'. The pilots also have access to extra oxygen cylinders. But so do the cabin crew (though they don't have any LOX system). Let's say the aircraft was depressurised while one of the pilots was out of the flight deck; the remaining pilot could climb to 45,000ft (though there would be no need to do that) and within 15-20 minutes, everyone other than the person at the controls would be dead. The climb could have been a result of a struggle, I suppose.

At that altitude (anything over 40,000 ft), ISTR that there isn't enough partial pressure to get the oxygen into your lungs anyway, so the masks are useless.  it was a known fact that decompression of a Concorde would kill everyone on board unless somehow the aircraft could descend 20,000 ft *extremely* quickly, before brain damage occurred.

Not quite true, Roger. You're right about the partial pressure being inadequate at high altitude when using compressed air, (I don't have my Avmed notes with me, so forgive the lack of numbers) but oxygen regulators will deliver 100% oxygen to the pilots under slight pressure so that they are adequate up to the 45,100ft that most Boeings are certified to - for a while. Above that, for extended operations one needs to be supplied with pressure breathing equipment as was fitted to the Vulcan and Victor and other aircraft that operated at 60,000ft and above.

The 45,000ft thing is a theory, not a fact. In reality, as I indicated earlier, there would be no need to climb above the 35,000ft the aircraft was already at.

Ok, Ben. You don't think that someone in a pilot's seat, being attacked by someone else (perhaps trying to pull them off the controls), could pull the yoke back but that they could push it forward. You're right, it probably can't happen. There's probably a rule against it, or a government department or something.

Sarcasm aside (and, believe me, I do feel I'm beating my head against the brick wall of your lack of understanding), I do not happen to believe that the aircraft climbed to 45,000ft because no-one has produced any evidence (or claimed any) to show that it did so.

Ben, the thing is the BBC and the people they are turning to are as uninformed as everyone else about what has happened to this flight. Their '10 theories' story is all speculation, admittedly speculation with an eye for what is plausible but still speculation. Tim through his professional experience is trying very hard on this thread to counter the least plausible theories, and the 45,000ft is one of these. Yes it is possible and it may have the effects identified but until someone shows a radar trace proving the flight went that high there is no evidence to say this scenario has any more merit than any other.

Before the investigators know what happened to this flight, one of two things and probably both need to happen:
1. A large number of conflicting parties are going to have to share radar data that will disclose their defensive air warning system capabilities so that the investigators can start to plot the course of the flight.
2. the aircraft with it's data recorders will have to be found and analysed.

Until then lets please try to keep to the information which has been released, though debating the implications of that information is obviously valid e.g the last radio message was reportedly from the co-pilot. Therefore was he the only person on the flight deck (captain on a comfort break) or as Tim suggested captain is pilot and has delegated radio monitoring / replying to the co-pilot.

Nil points, Paul! ISA is 15C at sea level, reducing by ~2C per 1000'. So FL200 is -15C; and the tropopause (approximately FL370) is about -58C. Above that the atmosphere (at least the part of it that aviation uses) is isothermal.

As for fuel consumption, the fuel flow at 2000ft will be around 6-7 tonnes per hour at the most economical speed - around 220kts. That's not much different from the fuel flow at 35,000ft but the speed over the ground will be around 500kts, so the specific fuel consumption (kg/nm) is much lower. The aircraft would have had around 55 tonnes of fuel at take off, and would have had about 45 remaining at the point it disappeared (I'm basing these numbers on the A330-300, which is a bit lighter and uses a bit less fuel). I believe it flew at around 30,000ft across Malaysia heading west for about an hour - so it now has around 39 tonnes. If it then descended to 2000ft and spent, an hour at that altitude (travelling 220nm in doing so, and leaving 33 tonnes), it could then climb to 10-15,000ft to stay clear of primary radars, and would have been able to fly about another 2000nm. That gives a pretty big circle of uncertainty.

Thanks, it's a long time since I had to know this stuff

OK, have we done this theory yet:

Could MH370 have been ‘swapped’ mid-air? (http://uk.news.yahoo.com/could-mah730-have-been--swapped--mid-air--haynes-manual-plane-expert-offers-his-theories-135928312.html#uPXFzXR)

If MH370 had a code of, say 4376, then it would be pretty easy to get another aircraft, say a Gulfstream 5 private jet, to fly up behind it and swap codes. The Gulfstream sets its squawk code to the same as MH370's code of 4376 then the B777 takes on the Gulfstream's code, and they then split... It would certainly make it easier for the B777 to continue on undetected...

That's one of the most sensible articles I've seen on this mystery, and most of his suggestions are believable. I think the idea that it crashed en-route to Langkawi is now ruled out, but the possibility that an electrical fire took out much of the communication systems and the fumes killed or disabled the pilots is a scenario that has happened before, and the aeroplane could have continued on basic autopilot functions until it ran out of fuel. However, there seems to have been some confidence among the authorities involved that the aircraft manoeuvred to follow some kind of deliberate course, and that would suggest that someone was in control. But the course it followed may just have been coincidental, or the pilots might have had time to get a single 'direct to' command into the navigation systems before expiring. On reaching the point selected in the 'direct to' command, the aircraft will either resume its last selected heading, or will continue on the track it assumed to that waypoint (I'm not familiar with the B777 autoflight systems, so I don't know the answer to that).

The world may not be looking to YACF for commentary on this mystery, but many members here are interested in - and possibly concerned about - the mechanics of what may have transpired. Flippancy is a currency here, and I'm as guilty of it as anyone, but I think that being flippant about the probable deaths of 239 people, and the concerns of all those who love them, is not within the principles of excellence that YACF espouses. I can educate and inform the discussion - I'm very happy to do so, and doing so helps crystallise my own thoughts about the situation, and I think that flippancy derails the thread and is incongruous in its context.

I appreciate that black humour is inevitable, and serves to lighten the horror. I've used it myself in many horrific situations, including on this thread. But black humour aimed at the overall concept of the tragedy is one thing, being flippant about the serious answers I've given in an effort to help you understand what's going on is, frankly, bloody rude.

No worries, Ben, really. As you can probably appreciate, this topic is fairly high in my list of priorities right now - unexplained aviation incidents don't sit happily with the culture that I am part of, where transparency and information sharing is crucial to the promotion of safety, and is something that pretty much is accepted by most countries and aviation authorities worldwide. Malaysia has fallen short of that ideal in many respects, and we are seeing face-saving take precedence over information and obstructing the search for the truth about what happened.

The problem is that, as far as I can tell from what I've seen on-line, ACARS and the transponder went off-line roundabout at the point where Malaysian ATC would hand over to Vietnamese ATC. The Malaysians may well have assumed that it had been picked up by the Vietnamese, and the Vietnamese, not seeing a response to their secondary radar, may well have assumed that MH370 was slightly delayed. There was a story that Vietnamese ATC asked the crew of a Japan-bound plane to try and raise MH370 on the radio, but all the flight crew could get was static and some indecipherable mumbling.

Tim,

Out of interest, how wide a road needs to be for a 777 to  have a reaonable chance to land on it?

Realistically, there's little chance of successfully putting a B777 down on a road - even the kind of road that in the cold war was reinforced for fighter operations. There might be a few very large motorway-standard roads which are straight for a mile and a half, with no over- or under-passes on which it could be possible, but that kind of road tends to be built to accommodate a large amount of traffic, and the motons might notice a B777 amongst them.

There are a number of disused WW2 (and later) airfields in SE Asia (including Burma) which could accommodate a lightweight B777, at least for a once-only landing, and I would imagine that there are several satellites looking for any evidence of such a landing.

Thank you, so in short we can say it is unlikely that the aircraft is still airworthy.  Landing on a remote desert road like the one I have shown upthread isn't realistic.

Further: ACARS is not an ATC tool.

It also incorporates the automatic datalinks to airline, airframe manufacturer, and power plant manufacturer where those facilities are implemented. It's provided under contract with one of the major aviation communications operators like SITA.

I have seen reference elsewhere to CPDLC/ADS being available in that area, which is a facility for the aircraft and pilot to datalink to ATC, but I've seen no mention of it being available to this aircraft. Our own on-board references make no mention of ADS or CPDLC being available in this area, but we don't operate round there so we have no need to know. If it had been available, and was switched on and working, there may have been more position information available. However, it's possible that the Malaysian spokespeople are lumping ADS/CPDLC in with ACARS, as the same display unit provides much of the pilot interface with this equipment.

Post by: Kim on 19 March, 2014, 12:18:46 pm
Before the investigators know what happened to this flight, one of two things and probably both need to happen:
1. A large number of conflicting parties are going to have to share radar data that will disclose their defensive air warning system capabilities so that the investigators can start to plot the course of the flight.

This is, I strongly suspect, what it comes down to.  Someone (maybe several someones) has military radar (or perhaps sonar or something exotic) evidence that it went down in the Indian Ocean, but on the basis that such a crash wasn't survivable, they're reluctant to reveal that they have that capability.

Only time will tell.
Title: Re: MH370 missing
Post by: TimC on 19 March, 2014, 12:42:27 pm
Ok, several questions here.

Kim: I raised that point some time back; national security or simple face-saving will be making some of the detective work very difficult. However, I do think that the investigators will find a compromise with most of the relevant nations for them to reveal what they know in a way which won't compromise their security position too much.

Spesh: the fact that the transponder was switched off where it was (IIRC, a few minutes before the boundary) would make it easier for Vietnam ATC to accept the aircraft apparently turning back without question; the total loss of both transponders will often not be acceptable for onward flight, particularly if the loss is in home airspace.

Ham: I'll have a look at that and get back to you.

Cudzo: see the related answer to Spesh's point. I would imagine that KL control had already notified Vietnam that the aircraft was being handed over, but they would have seen the squawk disappear and may have seen the subsequent turn. I suspect they would have deduced that the aircraft had initiated a return to base and not questioned it as MH370 hadn't made radio contact.

Or in my book, grossly malfunctioning electrical systems.

Ok, I've had a look. I don't know Jeff Wise's experience or why he feels the need to attack Chris Goodfellow's opinion (other than it sells his column!). I see no reference to 'violent turns'. He refers to 'vigorous navigating' with a 'sharp turn at VAMPI waypoint'. 'vigorous' and 'sharp' are hyperbole, and meaningless.

Following Chris Goodfellow's hypothesis, the likely course of action is that the captain would have initiated a turnback, quite possibly intending to go for Langkawi. He may well have asked the first officer to enter the first waypoints in the airways going that way, and the aircraft will then have followed that entered course whether or not the pilots were conscious. He may even have already prepared a route in the secondary flight plan in the box for that eventuality and simply activated it - I use the same protocol at all times of having a route to the most suitable diversion available in the secondary flight plan. It takes three button-pushes to set the aircraft on course to the high-level waypoint(s) appropriate to that airport.

The Boeing, unlike the Airbus, will fly pre-programmed level changes automatically. So if that secondary flight plan included level changes within it, the aircraft will execute those level changes - again, whether the pilots are conscious or not.

I have no idea whether Goodfellow's hypothesis is correct, but it has merit. Wise's comments do not.

I'm in serious danger at this point of finding the internet informative. I may have to revise my theory that planes are pulled through the sky by magic unicorns and instead are held aloft upon the breath of a million abbreviations and acronyms.

I think in any situation like this Occam's Razor should be deployed. A calamitous series of events in the plane, while improbable, is a far more likely theory than the plane being whisked away in some kind of giant gay gold heist to have been landed in a Miscellanistan field and repainted as a Mardi Gras float. That's complex, unlikely, and improbable.

I wonder how vulnerable all these systems are to a buggy firmware update?

In a sensible world, sensible, experienced engineers (AKA cynical old lags) would make sure there wasn't a single point of failure and hence it wouldn't be possible for software bugs to totally stuff the nav and electrical systems of the plane.

However, this world is definitely not sensible, and bean counters quite frequently override the suggestions of cynical old lags.

We do occasionally suffer small software glitches, but essentially these systems are quite simple from a software PoV. The issues we have are generally caused by inaccurate data in a content update - OS-stylee updates need an enormous amount of testing before they're ever let near an aeroplane, and thus are pretty few and far between. Our navigation systems also have two databases (there is a data cycle, and we'll have either the previous or the next cycle in reserve) so if one is corrupted we can load the secondary database.

Ah, ok. Well, I can't speak for the Boeing except to say that generally it's less automated than an Airbus. There will be electrical management units, but a fair bit of executive control rests with the pilots if they choose to use it. However, bus redundancy and degrade profiles and the like will be fixed and pretty unalterable. There's not a lot of software involved really, and I've never heard of a problem caused at a basic systems level by software updates; again, anything that the aircraft relies on in flight will be tested within an inch of its life before it's allowed near a plane.

I spent some years responsible for the airworthiness qualification of electrical parts.  That is mechanical, electrical and environmental qualification so I spent my time knee deep in Boeing, Airbus and other industry standard manuals.  It was only late in my time that I got involved with software qualification, and then only for non essential parts.  What amazed me was that Airbus listed a whole bunch of documents that had to be written to support the qualification of simple software, yet when asked what was supposed to be in those documents they had no set answer.  That was 10 years ago so I imagine they have learned from the people who have written those documents and it is now better described.  I repeat that this was only for low key and non essential parts.  Working with hardware was much  better defined by all parties.

Many years before that, I designed some parts that went on EAP which was our country's technology demonstrator for Eurofighter.  I remember talking to the test pilots who were going out to test a new piece of software - brave men!

Well, to be fair, it's easier to respond to specific questions, or to critique others' hypotheses, than it is to indulge in intelligent speculation in an information vacuum - and I'm not trying to sell newspapers or online columns with the concomitant need to be more sensational than the next guy!

..Many years before that, I designed some parts that went on EAP which was our country's technology demonstrator for Eurofighter.  I remember talking to the test pilots who were going out to test a new piece of software - brave men!

Presumably the important software would be tested by formal methods and not just the rather dodgy programming indulged in by your average IT bod.

With regard to Chris goodfellow's hypothesis, how likely is it that aircraft components could get hot enough to set the thing alight without diagnostics detecting it and communicating the fact to the pilot and to ground support?

Fire in an aircraft must be one of the oldest and most feared disasters that could occur, predating even the Wright Brothers!  i.e. hot air balloons.

Not very.  Each piece of equipment is subject to reliability calculations which includes any stress factor (such as temperature) on every component of that equipment.  The individual components are also derated according to their intended environment.  This is why you get commercial, industrial, Mil Spec and space ratings for integrated circuits.  Each component is also subject to "consequential damage assessment" i.e what happens to the piece of equipment if that one component fails.  Yes, things do fail and stuff happens - nothing is perfect.  Look at Boeing's problems with Lithium batteries on 787.  After years of banning Lithium primary cells they thought they had it cracked.

Electrical/electronic fires are very, very rare, but they do happen from time to time. I once had an inverter catch fire in a Hercules which prompted us to get the aircraft on the ground in less than 10 minutes from the cruise at FL280. Fortunately, Manston was very close. The Swissair MD11 crash near Halifax, NS, was the result of an electrical fire.* Both of these events were caused by shorting in wiring, not failures in individual components.


* There are several features of this crash which are or will be relevant to MH370, not least the fact that in hitting the water in one piece and at relatively high speed, there was very little debris on the surface for the rescuers to find - and they knew exactly where to look.

The problem in that case was that the In Flight Entertainment had been wrongly installed and connected to an essential power bus and so could not be isolated.  Flight crew of course would have no idea of this and would shed whatever power they could expecting to isolate the source.

Wiring shorts are very rare and arguably should not happen because the circuit breaker on that power line is rated to protect the wire - any equipment connected to that line has to look after itself.  e.g 16AWG wire will carry a 15A breaker.  So a real short will pop the breaker.  Wire insulation is also not random, it is approved by the industry and some are specifically forbidden by the aircraft manufacturers.

Indeed. While that was the cause of the fire, it's likely that had the crew spent less time diagnosing and more time getting the thing on the ground, they might have lived. That accident changed a lot of thinking about emergency handling. There was lots of other fallout about post-manufacture installations, but I expect you know more about that than me!

Title: Re: MH370 missing
Post by: TimC on 19 March, 2014, 06:54:04 pm
Pilots have control over all aircraft systems, to a greater or lesser degree. It is the pilots who are responsible for all communications with ATC and others, and there are several equipment failure situations (as intimated in the conversation about Swissair 111 above) where control over electrical loads is crucial. Many areas of the world are incompatible with some more modern datalink communication systems, and require it to be switched off to eliminate frequencies being saturated with automated aircraft systems trying to find a compatible receiver. These systems do fail, also, and in order to use the alternate system, the first must be able to be switched off. All that said, the next generation of transponders are likely to be automated, and will carry a totally unique identifier for the aircraft (like an IPv4 or 6 address) that will, if all the supporting systems work, identify the aeroplane and the flight it's operating at all times, including in areas where VHF communications and radars are not available. But there will still be times when it fails!

I don't think anyone envisaged a scenario where no-one had any idea where a plane went down. Though it has happened a few times, and I'm quite sure that the next generation of flight recorders will incorporate better batteries, and stronger transmitters that work on more wavebands. The 7000m underwater scenario is still going to be pretty tough to deal with, however. Eventually, we'll have real-time data download of the thousands of parameters the flight recorder covers, but we'll need a better broadband deal than we have now!

I was actually thinking of lower level than than; controllers for the electrical system.

Ah, ok. Well, I can't speak for the Boeing except to say that generally it's less automated than an Airbus. There will be electrical management units, but a fair bit of executive control rests with the pilots if they choose to use it. However, bus redundancy and degrade profiles and the like will be fixed and pretty unalterable. There's not a lot of software involved really, and I've never heard of a problem caused at a basic systems level by software updates; again, anything that the aircraft relies on in flight will be tested within an inch of its life before it's allowed near a plane.
in some fields e.g. X-rays there are safety critical decisions which aren't allowed to be controlled by software, so in an x ray machine for example there is a thing that says "if someone steps in the radiation area, switch the X-ray machine off" and that decision isn't allowed to be taken in code. probably the case on planes as well

Yes it is, though it's somewhat further than I (roughly) calculated, which is why I'm sceptical - hopeful, but sceptical*. And it's a bloody long way from anywhere, and the ocean's about 3000m deep there, which makes any detailed search really hard. If I've interpreted the information correctly, the nearest land will be Ile Amsterdam, a tiny French possession with no airport or facilities - or harbour. Difficult, to say the least.


*ETA. The other reason for my scepticism is that the 'debris' found is apparently about 24m long. That's a very large piece, and could only be a wing. For a wing to survive the aircraft's impact with water suggests either the aircraft was ditched under control (which has rarely been successful), or that its unpiloted glide angle after running out of fuel just happened to give it a relatively soft landing on the water. Either scenario is possible, but needs a lot of luck. This search hasn't had a lot of that, so let's hope this is what they're looking for.

BBC News channel has just screened an interview with Tony Cable, who was the AAIB's chief investigator for many years and probably the most credible commentator anyone's dredged up since this began. He's also a bit doubtful that such a large piece of the aircraft could survive, but accepts the possibility. He also mentioned the problems caused by how much it will have drifted in the 12 days or so since it crashed. My own experience of long-range SAR (one at very similar range from land to this report) is that the regional RCCs have very detailed knowledge of tides, currents and winds and are uncannily accurate when it comes to deriving drift vectors in remote locations.

The first search plane has returned empty-handed. The weather was too poor for a visual search below cloud. A USN P8 is on the way out there now. Ships are en route but it'll take some days to get there, and they can't really start searching until an air unit or another satellite finds something - the debris will have moved a couple of hundred miles since it was spotted.

Without air to air refuelling, the search aircraft can only spend about 2-3 hours on station. The RAAF has tankers, but I'm not sure if their Orions are compatible with their KC30A (A330) tankers*, or if their duty rules will allow very extended operations in peacetime.

A 5kt current over 12 days will carry an object 1440nm (2840km). That's a huge distance.

ETA: As far as I can tell, the position of the debris is not in an area of strong currents. Wind is more likely to have an effect if the debris has any air draught. Both wind and the small current present (anti-clockwise flow around the Indian Ocean north of the Antarctic Circumpolar flow) would tend to move the debris to the East and maybe a little North - ie closer to Australia.

Yes, see my edit above! That said, the search area was moved around 200km closer to Australia overnight, so they are estimating a significant drift.

AH, I guess that in the absence of a ransom demand or detection of the aircraft on any compatible airfield within its range, they must assume the aircraft lost. But that's significant information in itself, because it suggests that all those potential landing places have been scanned and dismissed.

200km is a long distance to cover on the sea for something without power, that's more than 100NM which is what a small sailboat would average on 24 hours. Typically abandonned boats or turtled multihulls tend to cover a few miles per day (may be 30 top).

I don't know if any other outlet has this, but the Washington Post has a map showing the last four "ping" radius arcs, rather than just the last one.

Some of the stuff associated with the other infrographics may require seasoning before ingestion, but the top map is interesting on its own:

One aspect of the incident that seems odd to me is the reticence of the plane manufacturer, Boeing.  The 777 has an excellent safety record which Boeing would wish to safeguard particularly with Airbus as a competitor.

A factor in this is the relationship between Boeing and its client.  The manner in which the aircraft was operated must be under scrutiny and that relationship is surely relevant, if only at this stage to decide what caused the aircraft to go missing in such a random manner.

It's inconceivable that Boeing is not intensely interested and concerned at this mysterious disappearance that seems to have been handled either ineptly or with duplicity but is certainly not confidence-inspiring.

What do you want them to say ? Without anything to go on there is nothing useful that they can say. It's not up to Boeing to comment on the operators maintenance schedule or whatever, they publish what needs to be done and it's up to the regulators to ensure that it is (the CAA in the UK for example).
If and when the plane is found Boeing will be all over it along with the crash investigators and will presumably release a statement after that.

Irrelevant I would think. A cockpit electrical fire wouldn't cause all transponders to switch off and the plane to change course. Also you would expect the crew to get off a mayday call if they did have a cockpit fire.

One of the scenarios we were discussing today enroute to Mumbai was a smouldering fire in the electrical or avionics compartments under the flight deck. It is entirely conceivable that a low-level fire (or, indeed, a water leak from a galley above) could randomly disable otherwise unrelated bits of kit - such as ACARS and the transponders and radios. If it was a fire, and if it subsequently produced significant amounts of smoke, it's also conceivable that it disabled the pilots, maybe only after they managed to get the plane turning to the west (with the VHF radios out, so no Mayday). The fairly random flight path subsequently might indicate that the aircraft was no longer on autopilot - maybe not even on fly-by-wire (the 777 has mechanical back up). If it was in trim when it lost all power, it would fly on but would oscillate in height and heading, and could be influenced by changing winds and fuel balance.

A succession of unlikely events, perhaps, but probably more believable than any hijack or suicide theory. And with several related precedents.

Boeing will be intensely concerned, and will be giving maximum cooperation. But they will not be allowed to discuss anything in public that might prejudice or influence any subsequent investigation - which might lead to legal action.

Inmarsat and the UK Air Accidents Investigations Branch have informed the Malaysian government that the flight definitely ended in the Southern Indian Ocean, in the area where various nations' aircraft are currently searching. They haven't as yet said exactly what data they have used to come to this conclusion, but it seems unlikely they would have announced this if there was any doubt.

In their sadly typical cack-handed style, Malaysia seems to have informed at least some of the relatives of the confirmed deaths of their loved ones by text.

According to the Telegrah, Inmarsat did a deeper analysis of the Doppler shift of the ping data that established the original loci for where the plane might be, and compared it with data from other aircraft on known paths relative to the satellite.

Seems legit to me.

So what are the chances that this is the first crash made more deadly by the pilot's secure cabin door (the post-9/11 change)?  If something bad happened to the pilots but the autopilot remained, the plane could have been given new instructions if someone could get into the cockpit... which, (if if if) would be a bloody ghastly way to end your hours.

Title: Re: MH370 missing
Post by: spesh on 24 March, 2014, 11:49:13 pm
Mind you, if the crew were incapacitated by accident, I'm not sure that it would fully explain all of the flight path between the last Malaysian primary radar contact, and the presumed final position in the southern Indian Ocean.

Based on an earlier post of yours, a couple of questions spring to mind:

How is the fuel balanced between the wing and fuselage tanks as it is consumed - is it manual, or can it be done automatically as part of whatever trim management (if any) is done by the auto-pilot?

If a plane is in a trimmed state with the auto-pilot disengaged, by how much would it oscillate in height and course?

I'm asking based on the personal hunch that the course changes were either due to a re-programmed system, or the pilot/s were in control until it turned south, outside Malaysian radar coverage.

Also, regarding the Cockpit Voice Recorder - is it working off a combination of microphones picking up ambient sound in the cockpit and tapping into the voice comms systems, or is it just one of the two options?
Title: Re: MH370 missing
Post by: TimC on 25 March, 2014, 07:20:55 am
Bear in mind it's just a hypothesis, not a fully-developed theory...

I explained a little earlier in the thread how the turnback and subsequent apparently deliberate navigation course may have happened as the pilots entered a contingency route into the Flight Management Computers before they were overcome by smoke or depressurisation. Or whatever. If the autopilot was subsequently disabled either by design or by a degradation of the electronics, and the aeroplane was in trim (in the B777, an automatic function only when the autopilot is engaged) it would oscillate around a datum level, though it would gradually climb as it lightened over time. The fuel system, assuming it works similarly to the Airbus (and I confess I haven't checked) will generally act to maintain an in-trim condition, though there are other functions and considerations which I may get a chance to look at over the next few days.

My intent in this hypothesis is to show that the course of the aircraft is not necessarily the result of anyone's conscious decision, and could well be the consequence of events outside the pilots' control or knowledge. Of course, it could be something completely different.

The Malaysian incompetence over the way they've managed information, particularly to the relatives, has gobsmacked me throughout this business. The insensitivity of the style of the announcement that the flight was definitely lost seems to have ignored hundreds of years of experience of how to inform people of the loss of loved ones without tangible evidence through shipwrecks, wars, etc. The language of many of their press conferences has been stilted, even evasive, rather than open - contrast that with the straightforward, believable, tough but carefully worded statements by the Australians about the search.

Don't get me wrong, I don't believe they've been trying to hide anything material to the investigation, but their desire to manage the loss of face and to stage-manage the release of information (do you really need an MC to formally introduce each speaker at a press conference - every day?) has hugely got in the way of humanity and empathy. And the categorical statement that everyone is dead - while almost certainly accurate - goes against the convention of 'missing - presumed dead'.

Andreas Prodromou got through the door of that Helios flight in two hours - just before the fuel ran out. Poor bugger. But he'd been living off an oxygen bottle. He may have been the only person left alive by then.

Actually, probably several oxygen bottles - they don't last long. Plus the cabin oxygen masks, which only work on demand (per block of 6, or thereabouts).  A resourceful chap, who held a UK Commercial Pilots Licence. There aren't too many like him working as cabin crew.

I'm now inclined to believe that the disappearance of MH370 was a deliberate act rather than an in-flight emergency, carried out by a person/people who had a good idea that the Malaysian authorities wouldn't handle the crisis that well, and took pains to ensure that the plane would be as hard as possible to find in a timely fashion.

YMMV, in accordance with whatever theory fuel flow sensing method you are using.
Title: Re: MH370 missing
Post by: Cudzoziemiec on 25 March, 2014, 01:29:11 pm
If true that might account for the specific timing, turning back just before leaving Malaysian airspace but when already effectively out of contact with Malaysian control on the ground, which seems to be key to the whole affair whether it were deliberate or not.

I might have missed something but to my mind there are only two things that are really puzzling:

The turn

The shutting off of transponders.


*IF* there was a catastrophic failure of systems, it could explain the first. Systems go down, pilots attempt to turn back, following a zigzag pattern to try to find identifiable landmarks. No radio systems to signal with. The failure could possibly explain the transponders - I don't really know. If said catastrophic failure also killed the cabin air system, then I guess people would be asphyxiated and the plane would keep flying until it ran out of fuel. That happened in the Helios case. In both cases you'd wonder why the heck the pilots didn't just descend but people do make mistakes.

It looks like the blog article sources are:

Excerpt from Malaysian Airlines release (incorrectly described as AAIB release*) sourced from:

Inmarsat images:

* From what I can tell from looking at the AAIB's site, they have MH370-related press releases for March 24th and 26th, but the former is "page not found" and the latter doesn't go into any detail.

Summary:
The captain, who'd been to an Anwar Ibrahim meeting just before the flight, was trying to use the plane & passengers as hostages to get Anwar released on his sodomy charges. The plane ran out of fuel before the undisclosed negotiations with the Malaysian government reached a conclusion.

Hmm.

Negotiating via a secret communications system so unique to MAS and the Malaysian government that no hint of it could be picked up by the intelligence services of the rest of the world?

What kind of 'negotiator' would put his negotiating card so far from the possibility of survival irrelevant of the success or otherwise of the negotiations?

In other words, bollocks.

The fact that the captain was a supporter of Anwar Ibrahim is something of a red herring too. Anwar was the Finance Minister (and very successful at it, too), and deputy Prime Minister. Politics in Malaysia has been dogged by corruption and litigation over the last couple of decades, and this guy seems to have both used and suffered the legal system there. In other words, he seems to be par for the Malaysian course. Supporting him and his party is no more remarkable in context than supporting David Milliband and Labour.

The South China Seas are an area of considerable tension and conflict between China (which seeks to claim sovereignty over them) and other countries such as Malaysia, Indonesia, Vietnam, the Philipines and of course Taiwan.  Whilst this may not explain the motive for a hijacking, it certainly does not make for openness and co-operations between those countries and China, it is also provides fuel for the conspiracy theorists in China.

The conflict is of course driven by the expectation there is oil and gas to be found beneath the seas.  It's not hugely newsworthy in the UK but the USA is increasingly involved in that part of the Pacific.

The mystery of this aircraft's disappearance isn't going to help matters.

I would be curious as to why the following doesn't stack up... i'm sure it doesn't, but curious as to why:
I had a thought which is that they were trying to land on antarctica.
Why, I don't know, and it requires the leap of faith that they didn't know they wouldn't have enough fuel to get there, and it sounds ridiculous but given the location, that is where it was heading for.
If you assume the following 'probables' are true: it was intentionally diverted, they weren't lost, they didn't intend to crash into the sea, and the plane didn't steer itself onto that trajectory (such as if the pilot(s) were incapacitated); then, it's the only possible intention left.
If this is the case, then the only possible reasons for the plane to have been heading towards antarctica are: they were intending to head for some other land but got lost, OR landing in the sea was intentional, OR, the plane was on autopilot (but if that's the case why didn't it continue its original course instead of steering south).

There's lots of *potential* reasons why they might have wanted to land there. Any reason that's based on them being able to land somewhere undetected and not be discovered. And it would probably be possible to land there, if they'd been able to do the distance.

And anyway, why does the pilot even need to know how much fuel is in it? Is it the pilots job to actually fill the tanks of the thing? All he needs to know is that it's got enough.
I haven't got a clue about most of the insides of a computer despite having been using one professionally for over ten years.

Ben, flying passenger aeroplanes is not analogous to riding a bike or driving a car. Things are not done off the cuff, or on the principle that 'the pilot doesn't need to know'.

I understand you are thinking aloud, but your train of thought is seriously derailed. If you wish to investigate and comment on serious possibilities of what might have happened to this flight, go away and do some studying of how airline operations work. If you just want to throw spanners in the works for teh lolz, there are probably better places to do it. You are Not Helping this thread, which is hopefully, and generally, about discussing the subject with a level of realism, and appropriate respect for the 239 people who have died.

If your intention really is for some respect to be shown for that, rather than to use it as a platform for showing how knowledgeable and great you are, then you might be better off dealing with the question as asked by discounting the possibilities of my logical inference one by one, rather than simply dodging it and rubbishing the headline idea.

Ben, I could waste my life knocking down each of your far-fetched hypotheses one by one. But as your knowledge of aviation, and your willingness to accept that it is a complex and very highly regulated business, is so limited, I would have to spend humungous amounts of time explaining commercial aviation to you from first principles. I don't have time for that. If you want to genuinely understand what happens to create and operate a commercial flight, and therefore what actions the pilots and others take to make it happen and conduct it in the air, there are a thousand websites out there with that information.

It seems to me that you are wilfully maintaining your ignorance while throwing ever more ridiculous suggestions out for 'consideration', then getting the hump when I and others tell you your ideas have no credibility. I don't want to put you on ignore because there are other areas of this website where you contribute valuable information. Perhaps I'll start asking you 'why maps?'.

Right, that's fine - but this is an exception to the rule. If you restrict yourself to only considering what could possibly happen according to the strict regulations of the "highly regulated" business, or only considering along the parameters of what normally happens to create and operate a commercial flight, then you will by definition never approach the explanation, because the regulations and the normal operation of a commercial flight are structured such that this can't happen. But it has happened. So some regulation has been broken. Why not that of the pilot controlling how much fuel goes in the aircraft? It's too dismissive of you to say 'that can't happen because it's a highly regulated business', because something that "can't" happen obviously has happened.
Can 5k miles worth of fuel even fit in a 777, for example? You claim not to have time to discount the hypothesis but seemingly do have time for an ad hominem argument.

Ben, please leave it out.  It must be really irritating for TimC to have someone argue with him over this.

Anyway, you've buggered up your own suggestion. You started out by suggesting that the pilot might have thought he could fly to Antarctica (why he would do that, nobody knows, certainly wouldn't be able to land there, but hey maybe the Raelians would help him). Then you've suggested that the pilot might not realise the plane was short of fuel. Seriously, you aren't stupid, please engage your brain.

From my understanding of passenger aviation, the amount of fuel loaded on a plane takes into account; Passenger weight, luggage, weather conditions, filed flight plans (since altitude and speed affect consumption per mile) and distance to be flown, of course. Then there is a safety margin added. No more fuel is loaded than necessary, as it costs money to carry fuel that isn't needed.
Alterations to weather conditions en-route will affect fuel consumption, so the pilot is constantly checking fuel usage against calculations. It's absolutely critical.

It's a suggestion, something that could have happened, not a plausible theory as to what probably did happen.
As for the fuel if it's physically possible that the pilot engineered putting enough in to get there. That's all. Physically possible. Not likely, not allowed accoridng to airline rules - no - I know. But physically possible.

The laws of physics are the only laws the theory has to defy for it not to be possible. Defying airline laws, legal laws of the land, common sense laws, laws of what "normal people probably would have done", that's all out of the window because we know all those laws have got to have been broken anyway for this to have happened in the first place. So it being against the laws of physics are the only real plausible reasons I will accept for why it couldn't possibly have happened. Such as, like I say, if that amount of fuel can't physically fit in a 777.

And I'm not sure why you think it couldn't have landed on antarctica, some ice is fairly smooth is it not? Some probably isn't, but I'm sure there are patches that are.

As for why this accident happened? We'll probably never know until the CVR/FDR is found. It took investigators 2 years to find the Air France that crashed into the Atlantic, and they had a good idea as to where to look. That accident report was a chilling read. It's also lead to a change in operating procedures at Air France....

It also meant in our company sim sessions on high altitude handling/normal attitude pitch power settings/stall recovery were incorporated into the syllabus for that year.

The range thing can be a red herring though; and Ethiopian 767ER (I think, correct me if I am wrong), was hijacked on the way from Addis to Nairobi.  The hijackers forced the aircraft east, and it crashed in the sea off the Comoros.  The hijackers were insistent that the 767ER could fly them to Australia as they had looked it up, but there was only enough fuel on board to get them to Nairobi with the standard reserve, where it was planned to refuel for the next leg.

In an interview with The Telegraph, he said that he had personally authorised the installation of “one of the most sophisticated radar” systems in the world, based near the South China Sea and covering Malaysia’s mainland and east and west coastlines, when he was the country’s finance minister in 1994.
It was “not only unacceptable but not possible, not feasible” that the plane had not been sighted by the Marconi radar system immediately after it changed course. The radar, he said, would have instantly detected the Boeing 777 as it travelled east to west across “at least four” Malaysian provinces.
Mr Anwar said it was “baffling” that the country’s air force had “remained silent”, and claimed that it “should take three minutes under SOP (standard operating procedure) for the air force planes to go. And there was no response.”
He added: “We don’t have the sophistication of the United States or Britain but still we have the capacity to protect our borders.”
It was “clearly baffling”, he said, to suggest that radar operators had been unable to observe the plane’s progress.

TimC isn't showing off his superior knowledge to put you down, he's suggesting you apply logic to information.

I have nothing to do with airlines or aircraft, except that sometimes I'm a passenger, but just by thinking about what airliners do, & things I've read in the press, I can work out why pilots need to know exactly how much fuel they have, & how far they can fly on that fuel.

(1) Airliners need long, straight, smooth strips of something hard to land on. They cannot put down on any random piece of land without wrecking the aircraft & probably killing all or most of the occupants. This is obvious to anyone who has read press reports of aircraft accidents, or cases where airliners have had to divert to emergency airfields.

(2) Suitable strips are relatively rare except in the most crowded parts of the world. Bad weather can make them temporarily unusable across large areas. Obvious to anyone who's looked at a map of the world, seen news reports, & thought a little bit, or has taken a long haul flight & looked out of a window.

(3) Aircraft do not always work perfectly, & when something goes wrong they must land. One of the possible causes of failure is a fuel problem. Obvious . . . .

(4) Because of the above, pilots must be aware at all times of how much fuel they have, & where they can get to on that fuel.

Quote
And I'm not sure why you think it couldn't have landed on antarctica, some ice is fairly smooth is it not? Some probably isn't, but I'm sure there are patches that are.
(5) There is nowhere in Antarctica where a Boeing 777 could land other than the bases, & probably not even there. Their runways are not meant for that sort of aircraft. This is obvious to anyone who has grasped (1), & has seen pictures of resupply flights to Antarctic bases - & such pictures are common enough that I can visualise some of 'em without ever, as far I can remember, ever having looked for them. I also have a good mental library of pictures of Antarctica, & it doesn't include a single picture of any terrain where it'd be possible to land an airliner. Ice caps are not like billiard tables.

Seriously, have you never, ever, seen a picture of sea ice, or a glacier, or of the Greenland or Antarctic ice caps? Do you walk around in a little bubble of unknowing, ignoring most of the sensory inputs available to you? Do you never, ever, read newspapers, or watch TV news, when aircraft accidents are reported? Have you never, ever, been to an airport, seen the length of the runways & thought about why they are made the way they are?

And as for the 'patches that are' - even if true, how the hell is an airline pilot going to find such a patch?

You say you're thinking about possibilities, but to me, it seems that you are NOT thinking. You don't apply any filters. Something comes into your brain & you spit it out without any thought, & then think only about how to justify it. If you were really thinking, you'd examine your own ideas.

Thus, if landing on antarctica wasn't the intention, then surely one of those things must have been the case. If not, why not.
It was a question about intention, really, not feasibility, or what actually happened. Reading too far into how likely that was to have been the intention is to miss the point and just leads down endless incessant rabbit warrens. The possibility suggested is that it was, however unlikely.
It's about, if it crash landed where 'objects' have been seen in the ocean, WHY was it heading in that direction. It certainly wasn't heading for australia, as it had gone way to the west of it. There wasn't any other land to be the destination.

It was “clearly baffling”, he said, to suggest that radar operators had been unable to observe the plane’s progress.


On the principle of cock-up being far more likely than cover-up (or that any cover-up is just to hide a cock-up!), I strongly suspect that whatever their radar may have been able to see, it wasn't being monitored particularly assiduously, and whatever recordings should have been made of the radar picture were not, or were overwritten before they could be examined. Operator error coupled with slack procedures are far more likely than a conspiracy involving several tens of people with a nefarious aim they don't want to actually tell anyone about!

As for the idea that someone could have considered flying the aeroplane to Antarctica, it's extremely unlikely. Firstly, although the aircraft could make it on a direct flight from KL to Pegasus field at McMurdo Sound (the direct distance is around 6100 miles, or about the same as to London to Anchorage), it would need fuel for around 11 hours of flight. It had nothing like that (it would have had about 7-8 hours fuel on board at take-off), and it had been flying for around three hours before it passed KL's latitude southbound. The correct course for a flight to either of the two ice strips that (only in the Antarctic summer) could conceivably take a B777 would have been over Western Australia. If the individual wished to avoid Australia, that would add around 3 hours to the flight time. Of course, the ice strips and associated stations are manned by military and support personnel of the USA, New Zealand and Australia, and would hardly have failed to notice a B777 arriving even had it had the range to get there. Nowhere else in Antarctica is there suitable terrain to land an aeroplane and expect to survive; even if there were, the survival time once on the ground would be severely limited - though perhaps longer than in the Indian Ocean!

The problem with what you say is that it makes no sense at all. We have to assume one of  -
that you don't mean what you say;
that you assume complete irrationality on the part of the pilots;
that you assume someone profoundly ignorant was in command, & chose to ignore all protests that what he was doing was suicide;
something else along those lines.

The pilots knew how far they could fly. They knew what conditions they needed to land. They would not attempt to fly to Antarctica, as they knew that it was no different from crashing into the sea.

It is just about possible that someone was standing over them with a gun & demanding they fly there, & ignoring all their explanations of why it was not possible, as with the hijacked Ethiopian airliner in 1996, but that's unlikely. If the hypothetical hijackers knew enough to keep the pilots flying the right course (unlike the Ethiopian hijackers) there'd be a good chance they'd understand the fuel gauges.

And there is, of course, the question of why anyone would want to fly to Antarctica. Once there, even if safely landed, they'd all die soon unless rescued. There's no possibility of keeping the plane & occupants hostage, as has been done in the past with hijacked aircraft. So it doesn't make any sense. You're assuming irrationality.

What I'm trying to do is show the unreality of your position, not 'look cool'. I'm being rational. I'm applying logic to information. You're choosing not to.

Maybe they didn't want to land on Antarctica. Maybe they wanted to fly round the world vertically. Maybe they wanted to see how far they could get before the plane ran out of fuel. Maybe they wanted to sacrifice the plane to Cthulu. Maybe they thought the plane was a perpetual motion machine.Maybe they believed they were being controlled by pixies from Venus. Speculation as to any of those suggestions is as worthwhile as speculating they wanted to land on Antarctica.

Quote
In an interview with The Telegraph, he said that he had personally authorised the installation of “one of the most sophisticated radar” systems in the world, based near the South China Sea and covering Malaysia’s mainland and east and west coastlines, when he was the country’s finance minister in 1994.
It was “not only unacceptable but not possible, not feasible” that the plane had not been sighted by the Marconi radar system immediately after it changed course. The radar, he said, would have instantly detected the Boeing 777 as it travelled east to west across “at least four” Malaysian provinces.
Mr Anwar said it was “baffling” that the country’s air force had “remained silent”, and claimed that it “should take three minutes under SOP (standard operating procedure) for the air force planes to go. And there was no response.”
He added: “We don’t have the sophistication of the United States or Britain but still we have the capacity to protect our borders.”
It was “clearly baffling”, he said, to suggest that radar operators had been unable to observe the plane’s progress.


On the principle of cock-up being far more likely than cover-up (or that any cover-up is just to hide a cock-up!), I strongly suspect that whatever their radar may have been able to see, it wasn't being monitored particularly assiduously, and whatever recordings should have been made of the radar picture were not, or were overwritten before they could be examined. Operator error coupled with slack procedures are far more likely than a conspiracy involving several tens of people with a nefarious aim they don't want to actually tell anyone about!



Your suspicions may be right.  The problem is that the suggestion is being made and there are those who would go along with it.

I believe the black box pingers have a detectable range of about 4km in good conditions. The sea bed in the area is up to 7km deep, so that doesn't bode well. I'm not sure what depth the UK nuclear boat can go down to, but it's likely to have very sensitive sensors which are probably about the best thing the search effort can get their hands on. But where to look? At least with the Air France 447 they had debris, a known location for the aeroplane going down, and the sea bed wasn't quite so deep (in fact the main debris was on a sandy area, IIRC). And it still took two years...

Cock-up on the part of the primary radar operators, born from the assumption that the course change was on instruction from Kuala Lumpur ATC, is the simplest reason why the air force did nothing - the Thais made the same assumption, and as their airspace wasn't entered by MH370, saw no reason to investigate further themselves.

Mind you, I can see where Ibrahim is coming from - given the local and regional rivalries and territorial disputes, the idea that an air force could be so slack doesn't bear thinking about, so it is natural that some people might wonder if it is more than just sloped-shoulder syndrome at work...

The problem with what you say is that it makes no sense at all. We have to assume one of  -
that you don't mean what you say;
that you assume complete irrationality on the part of the pilots;
that you assume someone profoundly ignorant was in command, & chose to ignore all protests that what he was doing was suicide;
something else along those lines.

The pilots knew how far they could fly. They knew what conditions they needed to land. They would not attempt to fly to Antarctica, as they knew that it was no different from crashing into the sea.

It is just about possible that someone was standing over them with a gun & demanding they fly there, & ignoring all their explanations of why it was not possible, as with the hijacked Ethiopian airliner in 1996, but that's unlikely. If the hypothetical hijackers knew enough to keep the pilots flying the right course (unlike the Ethiopian hijackers) there'd be a good chance they'd understand the fuel gauges.

And there is, of course, the question of why anyone would want to fly to Antarctica. Once there, even if safely landed, they'd all die soon unless rescued. There's no possibility of keeping the plane & occupants hostage, as has been done in the past with hijacked aircraft. So it doesn't make any sense. You're assuming irrationality.


I'm not assuming irrationality on the part of the pilots (or whoever was in control of the plane), I'm suggesting it.
I'm just not assuming rationality.
If anyone's assuming, you're assuming rationality. Well, you're assuming either rationality or the impossibility of a fairly far-fetched conspiracy.

It's into the realms of conspiracy theory, I know, but what if for instance there is an 'unofficial' base at antarctica, that only the conspirators know about.
I know it's some way along the spectrum of being similar to 'what if there is an illuminati and they are involved', and even though I accept it's unlikely (please try to remember that bit), it just doesn't make sense to me to box it off on the grounds that there absolutely "isn't" a base there because there isn't one that the media and general public, in fact anyone outside of a select group, are allowed to know about.

If there is an 'unknown' base, then that also gives you your reason for wanting to fly an airliner there - to staff it.
It's not an ideal way of doing it, and if it is the case then they'll probably be being bollocked right now for almost allowing it to get out.

But it just shows that you are thinking along the narrow lines of what you've been conditioned to believe by the media.

.... I'm not sure what depth the UK nuclear boat can go down to, but it's likely to have very sensitive sensors which are probably about the best thing the search effort can get their hands on...
Published figures for T class boats give an operational depth of 400m and maximum depth of 600m so if MH370 is 7K down then operating at 350-400m is not going to make a huge difference in detection range.  Tireless does have _very_ sensitive search/listening equipment.  Whether it's good enough to pick up a signal from a source 6.5 to 7K away I have no idea.  My guess is that it might be.  It's also possible that her high speed underwater (29kt max) is a factor as she'll be able to cover the ground more quickly than a surface vessel using a towed detector (assuming her listening gear can be used effectively at such speeds) nor will the search be disrupted by poor sea conditions.

Ben, if "somebody" had an unknown base on Antartica then I would imagine that it would already be staffed on a permanent basis. That "somebody" would have needed to ship in a lot of heavy machinery to smooth out the ice in order to make a runway (and make sure that it's thick enough to take the weight) and would then need to stay there to maintain that runway - I would guess that at a minimum it would need to be cleared and prepared again within 24 hours of being used - if the weather is pretty much perfect.

That's ignoring all of the other obvious issues with your irrational rationality.

It might technically be a desert, but there's a shitload of ice there, cold ice. Just for a moment imagine how the foundations for this runway might be laid - onto the ice? Excavate down to rock and level the rock and the pour concrete? Then there's the tarmac, whenever I've seen tarmac being put onto roads heat is used to soften it. That's going to require lots of extra energy to generate when it's minus bloody cold and you've got to make miles of the stuff.

All of the pictures that I've seen of aircraft operations into that part of the world use an ice runway.

Right, time for breakfast - it makes more sense.

Yes.  The whole bloody world noticed and in fairly short order.  The fact that we haven't so far found it after we _all_ noticed that it had "vanished" is (probably) due a mixture of Mk I cock-up, patchy surveillance and the fact that the Ocean is big; so big ....{insert Doug.

Not till it was too late. They didn't notice it had gone off course as soon as it did - only when it failed to land when it was supposed to.

If I was a very powerful person and ran a base in antarctica, and I needed to get some staff there rather quickly because of some emergency, I'd think commandeering a commercial airliner would probably be the way to go. I'd nobble ATC to make sure the only thing that got out was that it had "gone missing". A week or two later I'd then probably also go back and leave a few big bits of metal in the sea to make them think it had gone down there.

You really have just believed the official line hook line and sinker every step of the way and aren't really thinking objectively for yourself at all. If you want to go on believing the world is some kind of utopia that really is exactly as it is presented to be by official channels then carry on but you'll be deluding yourself.
Even if whoever owns the base wasn't powerful enough to keep satellites away from it in the first place, they've almost certainly got enough clout to keep the pictures off the internet.
If the likes of Microsoft and Google let it be public knowledge that they agree to keep each other's data centres off satellite imagery, then the world elite are certainly not going to go to the trouble of building a base then let it be discovered by commercial mapping satellite.

Ben you have overlooked one thing. No matter how big a super villain you are you can't operate a large commercial jet in secret. Since 9/11 any heavy without a flight plan or not identifying itself entering a counties airspace would soon find itself on the wrong end of an AMRAAM or the Russian or Chinese equivalent.

Well there's obviously unanswered questions in all of them but it doesn't necessarily mean in itself that anything salubrious happened. But in this case there is the circumstantial evidence that it WAS heading for Antarctica.

Anyway it doesn't even matter whether it was or not. You don't believe it could possibly have been, I'm not sure either way -keeping an open mind.
The current state of affairs seems to be that it's a race between Australia and China to find the black box.

So they are picking up signals one day to the next, but they are hundreds of kilometers apart. This pretty much confirms to me that a shark has indeed eaten something they are confusing for a black box, and is swimming around with it inside.

You don't believe it could possibly have been, I'm not sure either way -keeping an open mind.
The problem here is that your mind is selectively open. It rejects valuable information, & thus is led down blind alleys.

BTW, looking at the latest search areas, Australia looks like a much more logical destination than Antarctica. If your mind is so open, why have you kept pushing your Antarctica hypothesis, & ignored that? :P And I'm astonished that you reject alien abduction, demonic possession, & a time warp which flipped it into the future.

[re Australia] Well, it could be. I have considered that. It had gone a bit far south before it would have needed to turn east, but it could have done. I haven't "pushed" the antarctica theory, all I've done is suggest it and defend the physical possibility of it and repeat the initial question about the logic of it which has still gone totally ignored. The fact remains it is physically possible.
I've said before the only boundaries I place on what I consider to have possibly happened are the laws of physics, which is why I rule out alien abduction, demonic possession, etc. but don't rule out much else earth-wise. You appear to consider illegality, breach of airline procedure, lack of motive, woulda shoulda coulda, and all sort of other spurious boundaries as valid reasons why a particular possible outcome is completely laughable. Which, like I say, if a conspiracy is afoot, then that is the exact attitude the conspirators would like the general public to have.
Title: Re: MH370 missing
Post by: Bledlow on 07 April, 2014, 01:56:12 pm
Your thinking is weird. You're claiming (falsely, & with no evidence whatsoever) that I consider illegality & breach of airline procedures to be valid reasons for dismissing a theory. Where did I say that? It's bloody obvious that something has happened which is outside the normal parameters of what an airliner & its crew should do. You've also lumped them in with lack of motive, & what you call 'other spurious boundaries' (e.g. the laws of physics as they apply to airliners, the knowledge of pilots about what their aircraft can do, & their ability to read the cockpit instruments) - i.e. things which are definitely not spurious.

Then you claim that the only boundaries you apply are the laws of physics. That's inconsistent with your other claims. You believe, for example, that you're being told the truth about the flight path. Damme, you're naive! Do you really think that someone who could secretly build a runway in Antarctica fit for a Boeing 777 couldn't fake that?

I have a better theory. Ernst Stavro Blofeld is behind the whole thing. He didn't fly it to Antarctica, but to his secret base on one of the uninhabited islands of the BIOT, & he hacked the satellite to provide INMARSAT with false data, to conceal the route. There was something he wanted in the cargo hold, & it was the easiest way to get it without anyone knowing it had been stolen. He may then have had the plane flown under remote control to the area where the faked data suggested it had gone.

It's at least as likely as your theory. Can you argue against it?

You're also assuming that the laws of physics you know are correct. Poor fool! Don't you know about the theoretical physicists conspiracy to hide the truth?

Leaving aside the question of who even is "Ernest Stavro Blofeld", presumably a fictional character, then it's possible - but unlikely, because, as a conspirator it's far easier to conceal and censor news or to create similar but diversionary news than it is to create false news. False news can be checked and ousted as bullshit, but it's a lot more difficult to prove that somebody knows more than they're letting on.
If "Ernst Stavro Blofeld" had hacked satellite data then it could be possible to prove that, as some other satellite that he doesn't know about might have contradictory data. Far better to just dump some bits in an area with no satellite imagery coverage and just say it went there.
Title: Re: MH370 missing
Post by: Bledlow on 07 April, 2014, 03:15:05 pm
What do you mean, Blofeld is a fictional character? That's your conditioning by the media showing. And you're being extraordinarily naive to imagine that there are satellites such a powerful person doesn't know about.

How is anyone going to prove that false data recorded & transmitted by satellites is false? As long as it's consistent with the other data you have, it's safe. Much easier than secretly building a runway in Antarctica, for example.

Your arguments are inconsistent.

One of my architect friends a few years ago came up with the idea of landing 747s in Antarctica and then stripping them out and using the bodies as pre fabricated houses. The insulation that keeps planes nice and warm in the sky, should keep people nice and warm on the ground.

It's actually quite admired as a plan and is sold in various architect book shops around the world. Maybe the pilot was a fan.

Post by: Asterix, the former Gaul. on 12 April, 2014, 08:43:57 am
Should they find the 'needle' I wonder what form the investigation will take?  Given the disappointing Malaysian performance, I'd imagine they will not take the leading role*!  Nevertheless, their continued co-operation is essential.

It strikes me that had there been a deliberate attempt to 'disappear' a large aircraft this effort would be hard to beat**.  I read that the crucial  'black box' is unlikely to contain the data about the critical moment when the aircraft departed from its normal route since the 'tape' would have  'looped' since then, i.e. does not hold details of an entire potential flight endurance.  All the hijacker had to do was to keep the plane going long enough and bingo, no evidence!

It's also been said that after the French plane was found the investigators made recommendations about 'black boxes' whose implementation would have been very helpful in locating this one.  Evidently implementation of those recommendations (if there was any) did not include retro-fitting.

The form of investigation may well depend on what is found at the bottom of the Indian Ocean, and what can be recovered. It has been reported that the Malaysian government has already started its own investigation into the performance of the civil aviation and military authorities.

...  I read that the crucial  'black box' is unlikely to contain the data about the critical moment when the aircraft departed from its normal route since the 'tape' would have  'looped' since then, i.e. does not hold details of an entire potential flight endurance.  All the hijacker had to do was to keep the plane going long enough and bingo, no evidence!

You have to beware of journalists being sloppy with the terminology, as there are actually two data recorders. The Cockpit Voice Recorder (CVR) is the one that operates on a two-hour overwriting loop, and depending on what had happened, may indeed be of limited use. The one that lay people tend to think of as the "black box" is the Flight Data Recorder (FDR), which can record hundreds of parameters from the aircraft systems for up to 25 hours.

Not having a record of any conversation in the cockpit at the point when MH370 went off-course will be problematic, but there is a hell of a lot that the investigators can glean from analysing the FDR, such as autopilot engagement, altitude, control inputs et cetera, which will go some way to determining if the plane was actually being actively flown between going dark over the Gulf of Thailand and the point over the Andaman Sea or Indian Ocean where it finally turned south.

Post by: Asterix, the former Gaul. on 12 April, 2014, 06:29:23 pm
To be fair they did mention the second 'black box' and describe it much as you have done.  However, say 'crucial' because the article said that the information on that particular item would have been the most useful in quickly and maybe conclusively determining what went on in the cockpit. 

I'd imagine the Malaysian govt. is highly agitated about the whole business as they have lost a lot of face over the matter.  I'd love to think they will be open about any findings from their investigation but I'd rather see the lead role taken by more reliable authorities.

FedEx Flight 705 7th April 1994

A disgruntled airline employee flying in the jump seat attempted to bring down this flight in a bizarre attempt to claim on his own life insurance. He hoped that the money would go to his wife, even though his marriage was failing. The idea was to provide enough money for his kids to have a college education.

For the insurance to pay out he had to make it look like an accident. He pulled the circuit breaker for the CVR when the flight engineer was out of the cockpit so there would be no record of the fight.

Whether that is possible on MH370 I don't know but if something like this happened then there may be no recording at all.

So, the pinger's died, more or less on schedule if it really was MH370, & now they're doing a tedious back & forth scan of narrow strips of sea bed. Could be a long wait, but at least it looks likely that they're in roughly the right area.

I did my national service on a minehunter and apart from the fact that we only had capabilities for shallow waters (80m max if I remember well) thus there was no need to tow the sonar, they use relatively similar techniques to what we were using.

I think likelynees of success really depends on how rugged the seafloor is. On a sandy bottom you can see about anything even small (say the size of a spanner) easily. If it is rocky and rugged it becomes much harder. It is tedious work, boat goes at slow speed while people check all echos on the sonar. At least in the Indian Ocean, they won't be bothered by traffic! If there are big chunks of the fuselage still together it will be easier to spot.

There is an amazing quantity of stuff on the sea bed, people seem to loose propellers easily! Even if it was in 1999, we found (and destroyed) a British anti submarine mine which probably had been dropped by the RAF during WWII. Nowadays there are sthealth mines which are hard but not impossible to spot.

The MV Mauritania?  You sure?  Or do you mean the MV Armenia? There was no vessel called the MV Mauritania that I can find a record of but there were two vessels called RMS Mauretania, the first of which was scrapped in 1935 (not sunk in WWII) and the second of which was scrapped in 1965.

Step in Inmarsat:

Quote
UK satellite operator Inmarsat is to offer a free, basic tracking service to all the world's passenger airliners...

..The offer follows the case of Malaysia Airlines flight MH370, which disappeared without trace on 8 March...

Our equipment is on 90% of the world's wide-body jets already*. This is an immediate fix for the industry at no cost to the industry," Inmarsat senior vice-president Chris McLaughlin told BBC News...

..Cost is one of the reasons often cited for the reluctance of airlines to routinely use satellite tracking...

..Many observers were incredulous that a Boeing 777 could simply vanish, that its identification systems could be deliberately disabled in the cockpit, and that once the aircraft flew beyond the range of radar it was essentially invisible...

..[Inmarsat]already does something similar in the maritime sector. All distress calls from ships are relayed over its network free of charge...

..The official leading the hunt for the missing airliner says a full search of the suspected crash area could take up to a year.

Been there, searched that ...   ;D

At the frequency and amplitude that the black box was pushing out, the depth of water, our Deep Diving Depth and the sensitivity of the sonar (not the main one, the one that looks downwards) we reckoned it would have taken us 2 1/2 years to cover the search area with any significant degree of confidence. On the other hand, we had an unplanned week's OSP in Fremantle over ANZAC day.

I wish I had some idea of Indian & Indonesian radar coverage of that area. It's quite a long way from the Indian military air base on Car Nicobar. There's an Indonesian airport at Banda Aceh, which is closer - but still about 200 km away.

Essentially nothing, except make the aeroplane as light as possible before doing it. But I normally get by on as few as 10 wheels (A330), 12 (A340-300) or 14 (A340-600). 18 (the normal 747 complement) is just an extravagance!

Whilst looking to see if David Learmount had anything on the Air Asia crash in his blog at Flightglobal.com, I found an interesting post from just before Christmas (http://www.flightglobal.com/blogs/learmount/2014/12/mh370/) relating to MH370:

Quote
Some time ago, talking in this blog about MH370, I remarked that we should get used to the idea that we might never find the missing aircraft.

My logic was based on the fact that it had disappeared into a very big ocean and we knew very little about which way it went after it was lost from radar.

I am now more optimistic about finding it, because a consensus is building about where the aircraft is likely to be. The Australian Transport Safety Board, leading the search, has refined the search area down to a workable size, and several independent sources working on the sparse available data are coming up with theories that at least harmonise with the ATSB calculations, but then refine them somewhat.

In Flightglobal’s case, a senior Boeing 777 captain who got in touch with us has good reason to believe he’s calculated the final route of the missing Malaysia Airlines flight MH370. He has certainly submitted a convincing geometric explanation for his conclusions.

Link to B777 captain's analysis: http://www.flightglobal.com/features/mh370/

The virgin flight had lost one of its 4 hydraulic systems, so flaring would have been trickier. Gatwick isn't the longest of runway either, main priority would have been to get on the ground at the right point, esp knowing it was going to be a handful. Seems it was still pretty heavy too.

I guess they can reverse-analyse currents to determine its possible path but that won't help all that much - unless there happens to be an intersection with the line of the current (sic) search area.

Title: Re: MH370 missing
Post by: TimC on 30 July, 2015, 04:22:09 pm
Reverse analysis of currents failed in the Air France crash in the Atlantic - I think the models available are too simple to accurately reflect all the potential variables, and to try and do it over a year is probably impossible. All this will confirm from that point of view is that they're looking in the right ocean. More importantly, the families may soon be able to say definitively that the aircraft did actually crash and was destroyed and thus their loved ones really are dead, and the conspiracy theories about landing in Russia/abducted by aliens can be put to bed.

Anyone watch that program on BBC1 earlier this evening?

Much of it was covered up-thread, but right at the end, it brought up something new to me - someone had been looking at whether the flight of an aircraft can be tracked by perturbations in the WSPR transmissions, and based on his analysis, he reckons MH370 came down not that far to the east of the search box which ran along the arc of potential position based on the 7th and final successful handshake twixt plane and Inmarsat satellite.

Googling for MH370 and WSPR, I note that the Wiki page on MH370 and satcoms says Richard Godfrey had gone public with this in 2021, though there was varying mileage at the time because WSPR signals are quite low-strength:

Further research carried out since then may be promising...

Yes, I saw it - and I knew about Richard Godfrey's calculations some years ago. The issue with his calculations is that he couldn't establish (nor did he have the time to calculate) what effect other aircraft or surface vehicles (ships) would have on the disturbances he recorded. Hopefully the recruiting of Simon Maskell and the resources he can bring to bear will refine the calculations and give credibility to Richard's contention.

We were watching this and I said to Mrs Legs "wouldn't the solution to this be an ejectable, floating black box?"  Apparently this is now A Thing.

As a Ham operator, I find the science behind it fascinating : https://www.dropbox.com/scl/fi/vzftcvfx01lhbt3xfgyu5/How-Does-WSPR-Detect-Aircraft-over-Long-Distances-15FEB2024.pdf?rlkey=p8dcu8q3ww741joa922bdikng&e=1&dl=0

I would never have thought that so weak signals could be exploited like this. I've only done WSPR to test antennas!
