Another unlikely, and wierd, tail gun kill I got was on an La-7 when I was in an Il-2. I saw the La-7 diving in on me as I rolled. I jumped to the tailgun just after getting wheels up and started blazing away at the La-7. His tail popped off, even though I was shooting at his nose, and his nose flipped up, he went skyward, over on his back and down into the runway. Didn't even touch me.
