Bill,Thanks for the response and I realize you're not in charge of the british
glider training program. I can tell you what the USAF would probably do, in a
similar situation. They would immediately suspend all spin training in the
Puch, pending a full investigation.

This thread has brought to light the fact that the Puch can go into a flat spin
and a very good post told us that aileron against the spin would make it stay
flat. A bit of aileron may have been inadvertently applied, this can be
aggravated by G forces on the pilots arm or mis-rigging where the ailerons
aren't exactly in neutral when the stick is. I have seen this mis-rigging on
many occasions in the glider repair business.

I remember what our F-4 instructor told us about keeping the ailerons neutral
in the stall, "Think of it as though you had a hand growing right out of you're
belly button".
Hang in there,
JJ Sinclair
