On the afternoon of Thanksgiving eve, November 24, 1971, a smartly dressed man approached the flight counter for Northwest Orient Airlines at Portland International Airport and purchased a one-way ticket to Seattle. The name he gave was "Dan Cooper" as he paid cash to board Flight 305, a short 30-minute trip that would turn into one of the longest criminal manhunts in modern history. Once aboard, Cooper's requests to Flight Attendant Florence Schaffner were simple: a bourbon and soda, and a note to be delivered to the captain demanding $200,000 in cash and four parachutes. To add emphasis to his order, Cooper briefly showed Schaffner what appeared to be a bomb in the black attaché case he carried with him. Calm and polite throughout the ordeal, Cooper was now instructing the pilots to take him to Mexico City during the refueling stop in Seattle.
