In 2008, a U.S. Airways pilot’s gun accidentally discharged during a flight from Denver to Charlotte. The gun fired as the pilot — who was part of the FFDO program — was stowing the weapon, leaving a hole in the cockpit wall and an exit hole in the plane’s exterior below the cockpit window.

Well, shit happens, I guess. It’s just so unusual to read of an incident where a gun accidentally discharges. It’s like a billion to one chance.
