Uncanny Case No. 010: D.B. Cooper

D.B. Cooper is the pseudonym of an unidentified individual who hijacked Northwest Orient Airlines Flight 305 on November 24, 1971. He boarded the flight in Portland, Oregon, and later demanded a $200,000 ransom and four parachutes upon landing in Seattle, Washington. After releasing the passengers in Seattle and receiving the ransom, Cooper parachuted out of the rear of the Boeing 727 somewhere over the dense forests of the Pacific Northwest during a stormy night. Despite extensive searches and investigations by the FBI, Cooper's true identity and fate remain unknown, making the case one of the greatest unsolved mysteries in U.S. aviation history.
