Immediately after a high speed low 12 pass on a B-29, my wing falls off. Looking at the film, there are two small hit sprites on my wing and then it's gone. The bombs had just dropped a second before, so I doubt this guy could track and kill me that fast. Also, his guns never appeared to have fired. So what I'm guessing is, I flew through his bomb stream (on his end, not mine). The bomb(s) didn't drop 1,000 feet yet, so it was just collision damage.
The attack starts at 2:18 and is over at 2:20 - that quick and I'm toast.
