TTN:
Instead of flying straight and level, Victor K1 XA 930 tended to fly in a very slow corkscrew which was detectable through the seat of your pants in the back seats. The aircraft had at one time been in the hands of either Boscombe Down or Farnborough, I forget which, and rumour had it that it had once been barrel rolled. Whatever the reason it was definitely "bent"!
Probably this one then...
