01:36 A man named Dan Cooper hijacked a short flight between Portland and Seattle, showing a flight attendant a bomb and demanding $200,000 in cash, four parachutes, and a fuel truck.

03:09 During the hijacking, the flight circled over Puget Sound for two hours while the CEO of Northwest Orient Airlines approved the $200,000 ransom and arranged for parachutes and a fuel truck to be delivered.
