The hijacking occurred in 1971 when a mysterious man, who at the time went by the name Dan Cooper, boarded Northwest Orient Airlines Flight 305 to travel from Portland to Seattle. During the trip, Cooper called over one of the flight attendants and asked them to write out a note declaring that he had a bomb in his briefcase and that the plane was being hijacked. When the aircraft stopped at Tacoma International Airport, he allowed the passengers to leave in exchange for four parachutes and the sum of $200,000 in cash. After the plane had taken off again, Cooper strapped the bag of money to himself, put on one of the parachutes and jumped out somewhere between Seattle and Reno. No trace of him was ever found.
