Interesting aviation Stastistics from WW2

[Brewster Buffalo]

I also seem to recall that training losses for the USAAF (or perhaps that was for the RAF) were greater than operational losses.

I'd heard that but it was RAF losses in WW1. The only WW2 fact I have is that out of the 55,000 bomber command losses some 8,000 were in training etc which seems to support my WW1 theory.
