On November 24, 1971, one of the most famous unsolved crimes would begin to take shape: the legend of what happened to D.B. Cooper.
Cooper had hijacked a Boeing 727 and extorted $200,000 in ransom money, before jumping from the aircraft with a parachute into stormy weather conditions.
Nobody knows what happened to him or the money he took, despite manhunts and an FBI investigation that is still active today. In 1980, a little boy recovered several thousand dollars of the ransom money along the Columbia River. That was the last sign of anything related to the D.B. Cooper mystery.
