Historical true-crime feature — not breaking news. A passenger using the name Dan Cooper boarded a flight in November 1971 and vanished after a hijacking and ransom demand. Decades later, his identity remains unconfirmed.
The story in context
The incident involved Northwest Orient Flight 305, travelling from Portland to Seattle. The hijacker demanded money and parachutes, and the passengers were released. Investigators subsequently searched for the man and tried to establish his identity and movements using interviews and surviving evidence.
How the investigation developed
The case became one of the FBI’s best-known unsolved investigations. Physical clues, witness recollections and discoveries of some ransom money all attracted interest. Investigators reviewed possible suspects, but none has been publicly established as Cooper through definitive evidence.

Outcome and unresolved questions
In 2016, the FBI announced that it was redirecting the resources assigned to the case to other priorities. The announcement was not a finding that the hijacker had been identified. His whereabouts and fate remain uncertain.
