|On this day in 1971, a man known as Dan or D.B. Cooper jumped from the rear stairway of a Boing 727 as it flew at ten thousand feet over Washington State. He carried with him the $200,000* dollars in ransom and one of the four parachutes received when he released the passengers at Seattle-Tacoma Airport.
His whereabouts are still unknown to this day and the FBI case (codenamed Norjak) remains the world’s only unsolved hijacking. Link.
