I always thought the parachuting pilot who managed to down a Japanese fighter with his 1911A1 was impressive.
You can find this story on the Web, I just took a quick look, and noted many comments from people who don't believe it did happen, and some who don't believe it could happen.
I think it did happen, even though it seems like a million to one shot, these things can, and do happen. People do win the lottery, sometimes, after all.
One of the reasons I think it did happen was that I actually read about it in a real book, written by a "real" historian, some years before Al Gore (or anybody else) invented the Internet!
