The best fun I had in the RAF was when I was holding before the Victor OCU. I was sent on a 4 week low-level nav course on JPs at Linton. I was assigned Al Kolesky as my pilot for the course - great guy and a member of the Linton Gin display team. Al couldn't see why I should just sit there with a map, while all his other studes had to fly the a/c as well, so he gave me a crash pilot's course. Lesson one was a loop (no cissy straight and level for Al) which in a JP5 was easy even for me.
Great days, when the RAF could afford to send you off for what was basically four weeks of fun, learning skills that you would probably not need again (low level on tankers was below FL250!).
