dan cooper

Intro Dan Cooper is a name that has been used in several contexts, but it is most famously associated with the mystery of the hijacking of Northwest Orient Airlines Flight 305 in 1971. The individual who carried out the hijacking used the alias "Dan Cooper" (sometimes mistakenly referred to as "D.B. Cooper," which became the more popular nickname). The hijacker parachuted from the plane with a ransom of $200,000, and despite extensive investigations, his identity and fate remain unsolved, making it one of the most enduring mysteries in criminal history.
