As the Book says, if you take the pitcher too many times to the well .... like Paul Mantz did while filming Flight of the Phoenix (original one) after surviving numerous earlier stunts that were more dangerous.
Sometimes just being too damned sure of yourself is enough. Shane Panton, my closest RAF buddy and also Best Man at my wedding, used to scare me the few times he could persuade me to take a trip with him in a Chipmunk, his specialty being to grease it on right on the runway letters, or earlier, when landing. Said he didn't like taxying too far. Also used to like buzzing inhabitants of the remoter areas of Britain, reasoning that RAF planes didn't have registration numbers on the wings like civilian one do, and the serial numbers on a Chippie are pretty small so you couldn't read them from the ground without binoculars.
I used to reason with myself later: "This guy may not care about my life, but he must do about his own." But he gleefully flew into a hill in Wales two months after the wedding - probably trying to scare some sheep farmer. Silly bugger; he won the Sword of Honor at the Academy and would probably have retired an Air Marshall. Instead, he's been dead nearly 47 years.
