D.B. Cooper — Unsolved Hijacking

On November 24, 1971, a man using the alias Dan Cooper hijacked Northwest Orient Airlines Flight 305, a Boeing 727 flying from Portland to Seattle. He claimed to have a bomb, demanded $200,000 in cash and four parachutes, then jumped from the aircraft's rear stairs over southwestern Washington and was never seen again. Despite a 45-year FBI investigation examining over 1,000 suspects, the hijacker was never identified. It remains the only unsolved case of air piracy in U.S. commercial aviation history. The FBI officially suspended the active investigation in July 2016.
