But a big part of that is knowing what you're doing.

Sully had been flying airplanes for decades, and if you listen to the flight recorder, he sounded perfectly confident that he could "land" the plane in the river. If he had had any hesitation about his ability to do that, he would have tried to head for one of the local airports and the plane would have crashed. Part of it was luck, but a lot of it was the years of experience that he had.

You should check out the book "Deep Survival." It's about people who were in horrific survival situations, and the author tries to figure out why some people are able to withstand catastrophes and other people panic and die. It's one of my favorite books.
