The story is well documented and it is abundantly clear that the TSR2 was caught in heavy cross-fire.
The Labour Govt couldn't afford the number of projects (the Tories would have cancelled them if they'd remained in office), the US were desperate to put pressure on the UK to cancel the project and buy the US types. Add to the mix, the Admiralty, in the shape of Lord Mountbatten wanted to ensure their role into the future.
There is a DVD of the story, and it is sickening to watch Roy Jenkins and Denis Healey denying that it was their fault.
It would be good to put together the balance sheet showing how much was wasted chasing the TSR2 replacements.
The worst of it is that Govt still hasn't learnt any lessons on aircraft procurement.
Oh, and if it hadn't been for the rock-solid contract with France, Concorde would have gone as well
