It's amazing some of the situations people have survived. I once owned a book that collected documented cases of people surviving situations that should have been certain death.
Perhaps even more amazing, just for the sheer improbability, are cases where someone fell out of an airplane, and was saved by falling into another airplane. There is even at least one case where someone fell out of their open-cockpit plane, and the plane went into a dive and ended up below them, and they were able to get back into their own plane.
