Synopsis
Another Foot: What Really Happened to D.B. Cooper? by T. Allen Winn is a nonfiction investigation into the unsolved 1971 Northwest Orient Airlines hijacking, in which a man using the alias D.B. Cooper boarded a flight from Portland to Seattle, demanded $200,000 in cash and four parachutes, then parachuted from the rear stairs of a Boeing 727 over southwestern Washington and vanished with the money.
The book reexamines the case through available evidence, witness accounts, the recovered ransom money found years later along the Columbia River, and various theories that have circulated for decades. Winn challenges or revisits popular narratives about Cooper’s fate—whether he survived the jump, died on impact, or lived under another identity—drawing on FBI files, physical clues, and alternative interpretations of the jump conditions and subsequent search efforts. It presents the author’s conclusions about what “really happened,” aiming to offer a resolved or more definitive account of the identity, survival, and ultimate outcome of the notorious skyjacker while situating the crime in its historical context of 1970s aviation security and public fascination with the mystery.
