Honestly, I have no idea how he does that.
Some interesting points are;
1) when viewed in guncam speed, the AH bombers definately don't seem 'weak' at all!
2) the 'white glob' hit sprites look pretty natural in black and white guncams. This is probably due to the fact that since camera technology wasn't very good in those days, light sources such as bright flashes(incendiary, or HE) tend to get overexposure - and thus, look like AH hit sprites. Ofcourse, that's what it'd look like in films - not necessarily real life.
3) the fires and explosions, definately need some eye-candy upgrades!
