Quick answers
Who was D.B. Cooper?
An unidentified man who used the ticket name Dan Cooper on Northwest Orient Flight 305 on 24 November 1971. D.B. Cooper is a press error that stuck. No one was convicted. The FBI suspended the case in 2016.
What did he demand and receive?
He demanded $200,000 and four parachutes. Northwest Orient delivered that sum in $20 bills whose serial numbers were recorded, plus the chutes, at Seattle-Tacoma before the passengers were released.
Where did he leave the aircraft?
After the Seattle departure, over southwestern Washington, using the Boeing 727’s aft airstairs. The FBI’s first search box centred near Ariel; later wind models widened the corridor. No confirmed landing site was found.
Was any of the ransom found?
Yes. On 10 February 1980 Brian Ingram found about $5,800 in deteriorating $20 bills on Tena Bar, a Columbia River beach near Vancouver, Washington. The FBI matched serial numbers to the ransom list. The rest of the money remains unaccounted for.
Did the FBI identify a suspect?
The Bureau investigated thousands of names and publicly discussed several persons of interest. None was charged as Cooper. Richard McCoy, a 1972 hijacker, was a recurring comparison and was not adopted as the Flight 305 jumper.
Why is the case still unsolved?
No body, unused chute or unused ransom cache was authenticated. Witnesses aged. The 1980 river find did not lead to a person. In 2016 the FBI said active investigation was no longer justified.
Legal and airworthiness impact is real and specific. Cultural impact is larger and looser.
The case sits in a wider early-1970s hijacking wave; Cooper is the unnamed jumper that wave left behind.
Law & institutions
- Cooper vane and 727 stairs — A mechanical lock stopped Boeing 727 aft stairs from being lowered in flight. It is the named hardware lesson of NORJAK.
- Airport screening — Federal screening and hijack protocols were already tightening. Cooper became a teaching example for carry-on threats and ransom handling, not the sole statute.
- Air-piracy charging practice — The unsolved file left prosecutors without a defendant. Later hijackings were charged against known persons; this one was not.
- Freedom of Information afterlife — Released NORJAK papers feed historians and amateurs. They have not included a hidden verdict.
Culture
- The folk jumper — American song and film recast an unidentified hijacker as a trickster. That is folklore, not the FBI’s finding.
- Ariel gatherings — The Washington hamlet under an early jump box became an anniversary destination. Geography outlived the search.
- Suspect literature — A bookshelf of named dead men, none charged. This page treats those books as culture, not as a result.
- Composite as icon — The FBI sketch is more widely recognised in English than the ticket name Dan Cooper.
Money & scale
- The $200,000 bag — Recorded $20s, of which about $5,800 resurfaced in 1980. Inflation talk about the ransom is commentary; the serial list is the fact.
- Airline and Bureau cost — Northwest paid the ransom; the FBI spent decades on interviews and searches. No restitution hearing ever sat.
- A content industry — Books, tours and television turned an unsolved file into a durable English-language product.
The impact is a stair lock and a legend. It is not a conviction.
