I love that picture. Before seeing that picture, I really had my doubts about a WWII aircraft being able to fly with half a wing missing (which has helped me make it back to base plenty of times in AH). I used to wonder about the realism of it -- now I know AH has it right!
I saw that picture the first time in an Osprey book on the TBM (TBF/TBM Avenger Units of World War 2). I went to a talk at the Museum of Flight in Seattle to hear some WWII aces and a TBM pilot talk about their experiences (which was awesome). I bought the book so that I could get on it the signature of the TBM pilot afterwards.
In the picture, look how the fuselage behind the gunner is mangled, too. I wonder if the damage was a result of a collision?
