Spin
https://youtu.be/HosF_xKeeGE
A straight spin in a K6 glider from st remy last year. Note the bank angle.
I found myself inverted in a Beech baron in 1971 from a clean power off stall. The aircraft flicked completely inverted but with very little pitch down.
I similarly found myself inverted whilst instructing mountain flying in a grob glider from the cape gliding club. Figures of 8 below 200ft and with a bang caused by the shear from a thermal rising up the quarry face again inverted with nose more or less on the horizon.
Steve Fossett got into the lee and I've had quite a few surprises in the last 20 years flying in the mountains.
MY local paragliding wind reporter had a gust last week exceeding 140kph.
The guys I knew who flew Tante Ju were ex SR captain's and military..another ball game
