Met two guys who had wings fail and survive..one was Bwana Drum who was spotting Mau Mau in a tripacer. Took off before sun rise and would search for heat disturbances in the fog layer, then call in Lancasters to pattern bomb the area. Aircraft had been over stressed on a previous flight and he described to me how he played with the controls after one wing had fallen off. Rebuilt in east grinstead and had the GM plus police medal for gallantry.
The second was the Lak test pilot during a low level beat up at VNE when the wings fluttered and folded. Used Russian composites on a western designed glider but did't know that the materials fatigued at a different rate.
lost a very good friend who was ex frog carrier pilot who had been warned about aerobatics in his kit motor glider..thought he knew better.
Similarly watched a three axis hang glider doing aerobatics extremely badly at Coupe Icare..next day he pulled the wings off fortunately it had a ballistic chute.
Flown two aircraft which had been over stressed and not reported..one I found myself inverted over the new forest with my brief case on the ceiling..
