On November 24, 1971, a man claiming to be named “Dan Cooper”, purchased a one-way coach ticket, in cash, from Portland, Oregon, to Seattle, Washington. He then boarded a Northwest Airlines Boeing 727 and discreetly highjacked the plane for $200,000.00. At around 8:10 PM, Cooper opened the rear exit door while in flight, and jumped somewhere over southern Washington, with the cash and only a parachute, into obscurity. Cooper, the money and parachute, were never seen again. This case first aired on Unsolved Mysteries on October 12, 1988.
