The trouble with rockets is that they always look slow as they take off...but in the 1996 film "Apollo 11" there are library clips of the Saturn V a few minutes after launch, when it's almost horizontal against a blue sky, and moving like a very fast bullet.
As the tail of the Space Shuttle passed the top of the gantry it was doing 125mph. That's a heck of a shove from a standing start.
The Space-X seemed to get to 2,000km/hr pretty quickly.
Looking back at the video it did 0-62mph in 9 seconds. That's like my 2.0L Mondeo.
Then it was doing 700mph in 60 seconds!!!! That's much faster than my Mondeo.
2500mph at 2 minutes (I'm going to cease using my Mondeo as a comparison*)
*Faster than a Sniper rifle bullet.
14,000mph at 8 minutes !!!
I mean this thing really picks up speed nicely.
