I once knew a pilot who never made mistakes and would admonish and belittle those who did. For him checklists were for wussies. He'd been everywhere and seen it all. Then one day we learned that he'd made the worst mistake of all. It was something that most folks had on their checklist. With that he became yet another opportunity for human pilots to learn from the mistakes of others because we will never live long enough to make them all ourselves.
