I think McCain crashed 5 airplanes, it's amazing he's made it this long.
I read his book several years ago - from what I remember it was 3. The first was a T-34B in training (either PNS FL or CRP TX), a navy T-33/P-80 he ejected from(forget the Navy name) in the Chesapeak Bay and then the A-4 ejection. I could be wrong just what i remember from the book.
