What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) While glider soaring in VMC at approximately 20,000FT. MSL, near a lenticular cloud, the pilot stated that he thought frost was forming in the top of the canopy of the glider. When the pilot attempted to wipe the frost from the top of the inside of the canopy he discovered that the situation changed and that it was not frost but a cloud forming above the glider. The pilot stated that he turned on his turn & bank indicator, but that due to cold soaking, the instrument spooled up slowly and was not reliable. The pilot stated that his glider was lifted into the cloud and without the turn and bank, he lost control of the aircraft. The pilot stated that the aircraft broke up, and that after the aircraft broke up, he exited the glider and parachuted to the ground.
