D. B. Cooper.

D. B. Cooper is the name popularly used to refer to an unidentified man who hijacked a Boeing 727 aircraft in the airspace between Portland, Oregon and Seattle, Washington on November 24, 1971. He extorted $200,000 in ransom and parachuted to an uncertain fate

Only just discovered this guy, what a badman. Hopped on a plane, got a whisky soda, calmy explained what was going down to the flight attendant - "He seemed rather nice. He was never cruel or nasty. He was thoughtful and calm all the time". Got another whisky soda, paid for the fucker, touched down in Seattle, collected his dough, let off the passengers and took off again for Reno. Once he got there he stopped off for some more fuel and got back in the air once again. At some point between takeoff and landing the guy parachuted out of the plane while it was being tailed by two F-106 fighter aircraft and disappeared. Although the FBI maintain he probably died after jumping, the case remains open and his body has never been found. Like a boss.
