That is true in Vietnam,but not the one here in USA. I seem to remember that he crashed in the water in Gulf of Mexico? He went against his training for when these underwater escapes have to be accomplished and tore up the plane to get out instead of the simple (non destructive of Airplanes) way he was taught. He seemed to be a renegade type,and that can get you killed. B-1 Bob Dornan crashed twice also,but he is not what I call a renegade. Others may disagree.
Actually, IIRC, he was sitting in a plane on a carrier when another accidently dropped his payload on deck, and McCains plane was one that got whacked.
IIRC, the first one was during training in Corpus Christy Bay, the second one was onto the deck of a carrier, and the third was into Hanoi Bay.
