Shocking Example of Low Flying
The ski-slope story of the Canberra is partly correct. I was on PR7s in RAFG at the time (1968 ish) and the "offender" was a 14 Sqn B(I) 8 mate- not a QFI. Apparently he had been authorized for "low flying 4 ATAF, photographing castles and skiers!" Not sure who the senior was but it was either the CinC or his deputy. The major "crime" of which he was accused was that he had penetrated what was then the ADIZ just north of the Austrian border. I seem to remember that he got away with that one but he was indeed booted out for, I think, getting airborne with some gear locks still in. Apparently this was the last straw.
I also had heard the one about the bridge (on the Kiel Canal) and that the locals had solved the problem by hanging chains from the bridge. How true this story was, I don't know, for it was way before my time. It may even have pre-dated the Canberras. Sounds just the sort of thing the Venom/Hunter/Swift mopb might have got up to!
