I was in the air squadron that operated one of the Bulldogs that had a spinning mishap. The student got out but the QFI didn't. The wreckage was in the back of the hangar until the AIB came and took it away. Gave us the willies because we did full spins at least once a month.
All students should experience a full spin and I think FI's should be able to teach thus, however not every school operates a suitable aircraft. Recently I flew on an nav-ex with a student to Kemble. He then did the excellent Stall/Spin package with 'Ultimate High' and we then did another nav ex back home. It made an excellent day out but the student's performance was grossly affected on the return leg.
