Video - The Mystery of D.B. Cooper: The Great Hijack Escape

On November 24, 1971, a man using the alias Dan Cooper hijacked Northwest Orient Airlines Flight 305. Mid-flight, he revealed a bomb, demanded $200,000, four parachutes, and a fuel truck in Seattle for refueling. Upon receiving the ransom, he released the passengers but kept the crew. Somewhere over the Pacific Northwest, he parachuted out of the plane with the money. Despite an extensive manhunt, Cooper vanished without a trace. The FBI closed the case in 2016, leaving it one of America's greatest mysteries. Who was D.B. Cooper, and did he survive the daring escape?
