I wanted to add something by saying how much I enjoyed visiting the RAF museum at Hendon* last week and watching the dystopian cold-war video of big and noisy bombers taking off, that they've got running in the Vulcan's bomb-bay (Vulcans look a lot bigger on the telly, don't they?), but after the mutual respect about each others' head-of-metallurgy dads, I've come over with a wave of inferiority and can't really add much to the discussion. Save for the fact that with actually flying one of the f*ckers over the S Atlantic with an upside-down map during the Falklands War, I hereby declare TimC the winner of this thread.
*God. That Buccaneer in Gulf I rig-up's a sexy looking thing.
PS What's a graticule?
