Take a look, and see if anyone else was close enough to shoot at you, or if it was just you three.
Not that it matters, but there were four planes. When this first started, LA friendly was pointed up at the sky in a loop, so I didn't mention him, and I don't think he ever fired. At the end, he was still trying to get into position, and that's not where the fire was coming from.
I tried figure it out, re-looked it after killshot was brought up, sat in everybody's cockpit, watched fire at slow speed . . doesn't explain it.
Maybe there is something that we can't see in the low resolution JPGs you posted though.ed.
Trails are coming from the same distant place, and visible (to me) in the pics I posted, but I don't know what it looks like on somebody else's computer.

As to other comments, I don't know why sometimes friendlies I'm playing with in the training room show up as recent kills, and they can refute it all day long, but it doesn't change it. They do. You can force a friendly to crash by shooting them in the training room (under certain circumstances), because it can move them, either to dip their wing into the ground, or into a stall at top of a loop, etc., and maybe things like that are "logged" as a kill when they crash. I don't know. I only know this because I'll go into another arena and there's some Joe Bob from the training room in my recent kill list. So then . . are they in "the logs" as friendly fire? I'll bet I have a lot of friendly fire in "the logs". Therefore, somebody looking in "the logs", seeing I had friendly fire, is meaningless. There's no standard to apply that to. For them, maybe, because they don't go in the training room, or experience this (or don't know how to kill friendlies there).
