BEagle,
Re your post#25.
I was told many years ago by "someone who was present" that the cancellation of TSR2 followed a Cabinet meeting at which the then SofS Defence (Mr Healy) informed the PM that, whilst under test, TSR 2 had suffered a major structural failure of its wings.
This information (although incomplete) was quite correct - what was left out of this information was that the airframe on which this occurred was the airframe that was being tested to destruction.
