November 24th, 1971, the man known in the media as D.B. Cooper booked a ticket from Portland Oregon to Seattle Washington.
He told the air hostess he had a bomb (showing her cylinders wired in this briefcase) and demanded that the flight be met in Seattle with €200,000, four parachutes and a refuelling truck. That money is worth about €1.3 million in todays terms.
When the demands were met he allowed the passengers and cabin crew to depart in Seattle and told the Pilot to fly to Mexico. He told them to fly as slowly as possible without stalling the aircraft and to leave the undercarriage deployed. The rear exit door was left open for the flight.
Cooper parachuted from the aircraft somewhere between Seattle and Nevada.
Despite a massive manhunt he was never found. In 1980 a young boy camping with his family found three stacks of 20 dollar bills that came from the ransom. The stash amounted to €5,800.
The case remains the only unsolved act of air piracy in commercial aviation history. Arr me hearties. X marks the spot!
