When I lose a wing, its almost always the left. Is that the case for you guys? The circumstances make it difficult to pin down. I have had it pulling up off a target with no one within firing range, pulling up from a bomber pass from angles where it would be very hard for a gunner to hit (straight above) with no collision. Each one has seemed odd but I can't absolutely rule out that there wasn't another factor.
Perhaps we can collect data here.
