I know a chap who bears the same surname as myself and belongs to the same club as I'm fairly sure Pulse 1 belongs to who had quite a close shave.
It was an Oly, I think, scratching for the last lift on the ridge down by Firle Beacon. The spin was recognized immediately and recovery action taken. He said he felt the glider flying again just before the wingtip hit the ground. The observers came running over the hill to find........ no wreckage!
The ground contact had turned the aircraft that last 90 degrees to send him away down to the bottom of the hill to land safely!
If it had been 180 degrees more I might not be here now!
Its described in Peter Champion's book 'Glider Pilot'.
Chap in question is also responsible for the comment, "Remind me to talk to you about your landings!" I'll tell you about it another time.
Spin training saves lives.
