One of the most brazen criminals in American history, Dan “D.B.” Cooper was the alias of an unknown man who hijacked a Boeing 727 commercial airliner in 1971. After the plane landed at Seattle-Tacoma International Airport, the man demanded and received four parachutes and 200,000 in unmarked bills, at which point he released the passengers and ordered the plane and its four crew members to take off again and head for Reno, Nevada. Shortly after takeoff, Cooper lowered the aft stairs and parachuted from the plane. Though he is suspected to have landed somewhere near Vancouver, Washington, he was never seen again, and no body or remains of a parachute was ever discovered. What followed was one of the largest manhunts in American history, and although there have been over 1000 suspects in the case, Cooper’s true identity and whereabouts remain a mystery.
