For anyone who hasn't seen the episode of the aviators where Anthony tries soaring and glider aerobatics here is a link. I've had the pleasure to do glider aerobatic training with Manfred and it is a real rush, but for heavens sake, don't try these things in a 2-33! If you want to do glider aerobatics you need to have proper training, in a proper glider, following relevant air regs, and wear a parachute.
