A web search revealed very little info, so does anyone "out there" have any information on this "incident?"
Mid-air, one glider landed back on the airfield, second one - you know
the story. Not much more to be told even by people who were there.

It's typical for "publicity" of competition accidents to be zero.
Organizers' reasons are obvious, but on the other hand pretending
"nothing happened" doesn't make gliding community look serious.
