Really? Not saying it's not true, but I'm guessing a lot of that time came as an instructor on the civilian side. If so, how was he not suicidal? Seriously, I'm curious how many hours he had (roughly).
Oh, all of it came as a civilian, but he also (don't ask me how--he knew the right people, I guess) got to fly a P-51 at some point. He had ~1300 hours or thereabouts. I will say that it was not possible for him to do any better when he finished.
I don't know how he wasn't suicidal either, actually: one of his good friends told me that he would study somewhere on the order of eight hours a day. He was kinda crazy.
