The first 5 students I flew with as a new QFI on the JP all tried to kill me one way or another. In addition to trying to spin out of a stall recovery, student #2 (who became a very average ATCO shortly thereafter) caught me out with his novel crosswind landing technique. I had unwisely let him continue the landing as we were not quite halfway over the downwind side of the runway, and was totally unprepared for him kicking off the drift by using full rudder in the wrong direction. I took control (too late, obviously) and slammed the mighty Viper to fully loud (it was a Mk 3 JP...). I then showed student #2 that it was possible to nibble the light buffet whilst exiting the runway 30 degrees of heading at 0.5 feet, carefully avoiding the runway edge lights, which appeared to be about 14ft high. Student #2's comment: "That was fun, wasn't it Sir?!" QFI comment, from B2 list of useful phrases: "No, you c**t"
