An apocryphal but true (cos I know the stude involved) story from RAF flying training.
Said stude had some ability, but not much agression - a quality needed in a fighter pilot (aparrently!). Stude was given to a new creamy (a creamy is a pilot who is made an instructor straight from flying training) so that he could be made to fly his Jet provost more aggressivly.
Creamy gives stude control of the aircraft at 180 knots with the instruction that he is to attempt to overstress knowing however hard stude pulls he is not going to exceed the 6g limit.
No problem thinks stude and immediately lowers the gear 35 knots over the limiting speed!
Moral: Make your handover brief succint, but make sure the stude knows what you want him/her to do.
