The D.B. Cooper hijacking case, a notorious unsolved mystery, is back in the spotlight as the Federal Bureau of Investigation continues to search for evidence after 53 years. The event occurred on November 24, 1971, when a man using the alias Dan Cooper boarded a flight from Portland to Seattle. During the flight, he demanded $200,000 and four parachutes from the pilot.
Upon landing in Seattle, Cooper exchanged passengers for the ransom and parachutes before instructing the crew to fly to Mexico City. However, shortly after takeoff, he opened a door at the rear of the aircraft and parachuted out. His identity remains unknown.
Over decades, the FBI has interviewed over 800 suspects but has yet to identify Cooper or recover most of the ransom money. In 1980, a boy found some bills matching those used in the ransom along the Columbia River.
