Man, I hate stuff like that.
The report I saw said the B17 was in the P39's blind spot.
Looked like he didn't know the B17 was nearby and basically flew into it.
I don't see how the P63 didn't see the B17?? I think the P63 may or may not have seen the B17 but went across the back of it and just above it and got caught in "prop wash", lost lift and went right on top of the B17. Sad, sad, very sad for all of those on board. Godspeed all.
When you see it from another angle it looks like a direct cross of flight paths and not the B17's error. IMO
