It appears that McCain was a reckless pilot who liked taking risks. He crashed two other planes besides the one that took a SAM. It would be unfair to criticize him for getting shot down. He knew the SAM had a lock on him, but he hadn't dropped his bomb load yet. So he stayed on course, dropped, and got hit. Reckless, nerves of steel, stupid, all might be appropriate. But it would be hard to say he did the wrong thing since his mission was to bomb a target, munitions or AA station, I forget.
