Slight aside, but with regards to the detent sytem to limit movement, if I recall correctly when Cottesmore was the TTTE back in the late 80's the tensions of the detent on one tornado were set incorrectly (I think not enough shim in place) and someone managed to sweep the wings while the flaps were down
Excuse the lack of possible correct terminology, I was on work experience there and was only 14! (It might have also been a tall tale told by a liney)
