D. B. Cooper is a media epithet used to describe an unidentified man who hijacked a Boeing 727 on November 24, 1971, extorted a US$200,000 ransom (equivalent to $1.51 million today[1]), and parachuted to an unknown fate.[2] He was never seen again, and only $5,880 of the ransom money has been found. The incident continues to influence popular culture, and has inspired references in books, film, and music.[3]
