On November 24, 1971, a man named Daniel Cooper purchased a $20 one-way ticket on Northwest Airlines. His flight was 305 from Portland, Oregon to Seattle, Washington. Cooper was in his mid-forties. He dressed in a business suit, overcoat, brown shoes, a white shirt and a black tie. He also had a briefcase and a brown paper bag with him.
Before the flight, Daniel Cooper requested a bourbon and soda from the flight attendant. Cooper handed the flight attendant a note after the plane took off. She initially put it in her pocket without looking at it. But Cooper told her, “Miss, you should look at that note.” “I’ve got a bomb.” Cooper then informed her that the bomb was in his briefcase and requested that she sit next to him. When he opened the briefcase, he found red-colored sticks surrounded by a tangle of wires.
Daniel Cooper instructed the flight attendant to jot down everything he said and deliver it to the Captain. “I want $200,000 by 5 PM. in cash, exclusively in $20 bills, in a knapsack,” the note stated. I’d like two back and two front parachutes. When we land, I want a fuel truck waiting for us. No funny business or I’ll do the job. The ransom money by FBI agents gathered from several Seattle-area banks. He purchased parachutes from a local skydiving school in Seattle.
Daniel Cooper let all of the passengers and a portion of the crew to get off the aircraft. He has declared that his demands had been fulfilled. He instructed the remaining crew members to refuel the aircraft. Then steer it towards Mexico City while maintaining an altitude below 10,000 feet. Cooper wore a pair of black wraparound sunglasses during the flight. This ended up appearing in the official sketch and becoming well-known to all those looking into the case. Cooper leaped out of the back door of the aircraft with the money and two parachutes. It happened just after 8 PM, somewhere between Seattle and Reno, Nevada. He vanished from view forever.
The 45 years are over for seeking. A massive manhunt began but no one find or identify the man. Even no clue to determine what happened to Daniel Cooper after he jumped. It is one of the most significant cold cases in US and FBI history.
