Rustle,
Quite happy to be corrected. What a sad story. From the reading of that, he would have been O.K. if he had pushed or pulled the stick rather than turned. The tip of his left wing hit the tip of the gliders right wing with the AA5 in a right turn. He was still unlucky in that the damage appeared to be minor but his mass ballance weight got jammed.
I don't know if that was the result of a search or if you remembered it. If that is the most recent one there is, it was ten years ago.( I am not trying to start a contest, it's just that I feel that this is an overrated risk)
