CASE #5DU8MK · 2 entities · 1 connections
D.B. Cooper
The only unsolved skyjacking in American history — and the FBI closed the case without ever learning who he was.
On November 24, 1971, a man calling himself Dan Cooper hijacked a Boeing 727, demanded $200,000 and parachutes, then jumped from the plane's rear stairs somewhere over southwest Washington and was never seen again.

Quick facts
- →He bought his ticket in cash under a fake name and ordered a bourbon and soda mid-hijacking like nothing was wrong.
- →$5,800 of the ransom cash surfaced on a riverbank in 1980 — partially decayed, and never fully explained.
- →The FBI investigated over 800 suspects across 45 years before formally suspending the case in 2016.
- →No parachute, body, or the rest of the money has ever been found.
