I ran out of ammo trying to down some Lancs that were heading to drop the last FH on a base we were losing. Having watched the DogFight episode about Germans ramming B17s recently, I said what the heck.
No one else would reach them in time and I was already a bit shot up, so I intentionally collided. Hmmm, brought one down with no damage to me. OK, I'll try another with the same basic hit...down he goes and still no damage to me. Might as well go for the last one...yep, same hit, down he goes.
Probably just a combination of his view vs mine and maybe the certain way I hit him, but I won't be trying it again. It was lame on my part but I sorta got caught up in the moment and curiosity about finding what could be a bug. I did bail and give him the kill as his last Lanc spiraled downward.
Won't be trying it again because I hate collisions and discovering a way to reliably down bombers by colliding would be Pandora's box.
