I remember visiting Boscombe Down in 196? as an air cadet. We were allowed to scramble all over a TSR2, and I vividly recall a mock heraldic device had been pencilled on the fuselage with the motto "Harold Wilson's Folly'.
The whole navigation and weapons system was analogue, so must have weighed a fair bit. With a digital update it might have done what it was designed to.
There was a rumour that a couple of airframes were kept in a flyable condition for some time after they were all supposedly scuttled.
The design of the Jaguar also seemed to have borrowed many of the TSR2's characteristics, albeit on a smaller scale.
