In 2003 I lost my fin and tailplane in a midair. I was able to get out very easily. I and the pilot of the other glider involved were very lucky. We both used our parachutes and were completely uninjured. I would not speculate on why the pilots of this K21 were unable to get out and am surprised that the report did not address that aspect. Would any of you ground a tug because the Flarm was giving problems?
