D. B. Cooper
Summary
D. B. Cooper is a media epithet for an unidentified man who hijacked Northwest Orient Airlines Flight 305, a Boeing 727 aircraft, in United States airspace on November 24, 1971. During the flight from Portland, Oregon, to Seattle, Washington, the hijacker told a flight attendant he was armed with a bomb, demanded $200,000 in ransom (), and requested four parachutes upon landing in Seattle. After releasing the passengers in Seattle, the hijacker instructed the flight crew to refuel the aircraft and begin a second flight to Mexico City, with a refueling stop in Reno, Nevada. About 30 minutes after taking off from Seattle, the hijacker opened the aircraft's aft door, deployed the staircase, and parachuted into the night over southwestern Washington. The hijacker has never been found or conclusively identified.
In 1980, a small portion of the ransom money was found along the banks of the Columbia River. The discovery of the money renewed public interest in the mystery, but yielded no additional information about the hijacker's identity or fate, and the remaining money was never recovered. The hijacker identified himself as Dan Cooper, but a reporter confused his name with another suspect and the hijacker subsequently became known as "D. B. Cooper".
For 45 years after the hijacking, the Federal Bureau of Investigation maintained an active investigation and built an extensive case file, but ultimately did not reach any definitive conclusions. The crime remains the only unsolved case of air piracy in the history of commercial aviation. The FBI speculates Cooper did not survive his jump, for several reasons: the inclement weather on the night of the hijacking, Cooper's lack of proper skydiving equipment, the heavily wooded area into which he jumped, his apparent lack of detailed knowledge of his landing area, and the disappearance of the remaining ransom money, suggesting it was never spent.
