Here is what happened with the friendly 25T kill. I had spotted two enemy helicopters at Poti. I shot one with a mav and was trying to reacquire the second one when I heard this low rumbling and figured the SU that had my call sign stenciled on his airplane with 4 or 5 little kill stars next next to it was back, so I broke off with the helos, dumped all my weapons and got some altitude..
A few minutes later I saw a glimpse of an airplane cutting across my path a few miles ahead, so I zoomed in and saw it was a SU.. I cut into his turn, made up some distance and shot my first missile. It tracked and it looked like it exploded close by but the SU kept on going.
I shot the second missile and it was a clean miss. I got behind him and sprayed a long burst of gun in his general direction and I noticed a small piece of something fall off of his airplane. I pursed him for a few minutes hoping to run him down, but he wasn't slowing. I turned back and headed to Poti to see if I could re acquire the second helicopter. After searching for a while I found him and made a few snapshot gun passes and missed so I extended a bit, rolled in and just hammered the dude with 30mm. Right as it exploded I got dumped out of the game..
Thought my game crashed until someone on comms said I was kicked for blue on blue.. This SU was friendly, and I did some damage, but it took like 20 minutes for him to explode. Turns out that stray 30mm Bullet that he was unlucky enough to run into caused some cascade damage that eventually took him out.
