On November 24, 1971, a man using the name Dan Cooper boarded Northwest Orient Flight 305 from Portland to Seattle, claimed he had a bomb, demanded 200,000 dollars and four parachutes, released the passengers, and then jumped from the rear stairs of a Boeing 727 into the rainy Pacific Northwest night. This episode follows the hijacking, the crew's role, the ransom, the Tina Bar money discovery, the evidence left behind, the FBI's long NORJAK investigation, and the way an unresolved aviation crime became a global legend.
