D. B. Cooper
On November 24, 1971, a man calling himself Dan Cooper, a.k.a. D.B. Cooper, bought a one-way ticket on a flight bound for Seattle, Washington. While the flight was en-route, he hijacked the plane and made several demands. Later, while the plane was in the air, he jumped out of it with a parachute with over 200,000 ransom money he had been given. He was never found.
