Ok, maybe its just me, but I would never sue another club member over an airplane. Its just not worth it, and I don't want to sue anyone. I have to agree with those that say mid-airs are part of the risk associated with the hobby. I don't think anyone wants a mid-air, including the other guy, regardless of who came out better in the aftermath. If the other guy was at fault, (as in, he landed on my plane in the pitts), I may tell him he owes me, but thats about it.
