He ordered a drink — bourbon and soda — while the flight was waiting to take off. A short time after 3:00 p.m., he handed the stewardess a note indicating that he had a bomb in his briefcase and wanted her to sit with him.

The stunned stewardess did as she was told. Opening a cheap attaché case, Cooper showed her a glimpse of a mass of wires and red colored sticks and demanded that she write down what he told her. Soon, she was walking a new note to the captain of the plane that demanded four parachutes and $200,000 in twenty-dollar bills.

When the flight landed in Seattle, the hijacker exchanged the flight’s 36 passengers for the money and parachutes. Cooper kept several crew members, and the plane took off again, ordered to set a course for Mexico City.

Somewhere between Seattle and Reno, a little after 8:00 p.m., the hijacker did the incredible: He jumped out of the back of the plane with a parachute and the ransom money. The pilots landed safely, but Cooper had disappeared into the night and his ultimate fate remains a mystery to this day.
