The Only Unsolved Airline Hijacking in U.S. History: D.B. Cooper
November 24th, 1971. An unknown man extorts $200k from Northwest Orient Airlines in Washington after taking a Boeing 727 hostage. He releases all the hostages in Seattle upon receipt of the ransom money. He then instructs three of the crew to continue flying on to Mexico. Only the man had no intention of flying to Mexico. He dons a parachute, opens the rear stair of the 727, and jumps out into the cold and rainy night. Despite an exhaustive investigation with full FBI involvement, the man has never been identified, the bulk of the money never located, nor the crime solved. This also stands as the only unsolved airline hijacking in American history.
