On the night before Thanksgiving in 1971, a man who had bought his plane ticket under the name "Dan Cooper" lowered the rear stairs of a Boeing 727 somewhere over the dark, rain-soaked wilderness of southwest Washington, strapped $200,000 in cash to his body, and jumped into the night. He was never seen again. More than fifty years, hundreds of suspects, and one formally closed FBI investigation later, it remains the only unsolved commercial aircraft hijacking in United States history.
Background: A Bomb Threat, a Ransom, and a Jump Into the Dark
On November 24, 1971, a nondescript man calling himself Dan Cooper purchased a one-way ticket for Northwest Orient Airlines Flight 305 from Portland, Oregon, to Seattle, Washington. Mid-flight, he handed a note to a flight attendant claiming he had a bomb in his briefcase and demanded $200,000 in cash and four parachutes upon landing. Once the plane touched down in Seattle, all 36 passengers were released in exchange for the ransom and parachutes, while the flight crew remained aboard. The plane took off again, ordered toward Mexico City at low altitude and reduced speed. Somewhere over the rugged, forested terrain of southwest Washington, at roughly 8:00 p.m., the hijacker lowered the aircraft's rear stairway and parachuted out into freezing rain, carrying the ransom money with him. The plane landed safely in Reno, Nevada, without him. A media transcription error during the initial reporting turned "Dan Cooper" into "D.B. Cooper," the name that has stuck ever since.
The Investigation and the Money
The FBI opened an extensive investigation it called NORJAK, for Northwest Hijacking, interviewing hundreds of people and pursuing leads across the country. Within five years, agents had considered more than 800 possible suspects, narrowing the list to roughly two dozen without conclusively identifying any of them. The case's most significant physical break came nearly a decade later: on February 10, 1980, an eight-year-old boy named Brian Ingram, on a family picnic along the Columbia River near Vancouver, Washington, found $5,800 in decomposed twenty-dollar bills partially buried in the sand. FBI analysis confirmed the bills matched the ransom's recorded serial numbers. It was the only portion of the $200,000 ever recovered, and its location, far downstream and years later, raised as many questions as it answered about where the rest of the money, and Cooper himself, had actually gone.
In July 2016, after 45 years without a definitive identification, the FBI formally closed the active investigation, describing it as one of the longest and most exhaustive in the bureau's history, and stated it would only revisit the case if someone recovered the actual parachute or additional ransom money.
The Suspects
Formal closure didn't end the search. Following a 2017 Freedom of Information Act request, the FBI released letters allegedly sent by Cooper to newspapers shortly after the hijacking, including one containing a nine-digit numerical sequence some amateur investigators believe was intended as a signal to a possible accomplice. In 2023, the children of suspect Richard McCoy Jr., who died in 1974, presented investigators with a parachute rig and logbook they said had been stored in a family shed for decades, arguing it placed their father at the scene. Independently, researcher Eric Ulis has pursued a theory centered on a man named Vince Petersen, based on a rare titanium alloy detected on a necktie Cooper left behind on the plane, a metal Ulis traced to a small manufacturing facility where only a handful of employees, including Petersen, worked in 1971. None of these leads has been independently confirmed by the FBI.

| D.B. Cooper | 1971 | Unidentified hijacker, parachuted from a commercial flight | Unresolved; FBI formally closed active investigation in 2016 |

| Percy Fawcett | 1925 | Explorer Percy Fawcett and his son Jack | Unresolved; believed lost in the Amazon |
| Michael Rockefeller | 1961 | Heir Michael Rockefeller, lost off New Guinea | Unresolved; contested theories persist |
Theories and Explanations
Died in the jump. Most investigators consider this the most probable outcome. Cooper jumped at night, in freezing rain, into densely forested and mountainous terrain, without adequate cold-weather gear, using a parachute rig that included one chute sewn shut for training purposes, a detail that has led some experts to question whether he was as experienced a jumper as initially assumed.
Survived and disappeared. A competing view holds that Cooper successfully landed and escaped, pointing to the lack of any recovered body and treating the isolated resurfacing of a small portion of the cash nearly a decade later as consistent with natural riverbed movement of buried, deteriorating bills rather than evidence against survival.
Named suspects, never confirmed. Over the decades, investigators and amateur researchers have proposed numerous specific individuals, including Richard McCoy Jr., Kenneth Christiansen, Robert Rackstraw, Lynn Doyle Cooper, and Vince Petersen. Each theory rests on circumstantial evidence, personal testimony, or physical clues that have generated genuine investigative interest without ever producing definitive confirmation.
Why the case stays open despite official closure. The FBI's 2016 closure ended active federal investigation, but it didn't resolve the underlying mystery, leaving amateur investigators, journalists, and Cooper's own suspected relatives still actively pursuing leads nearly a decade after the bureau stepped back.
The Curious Connection
D.B. Cooper offers this series its first genuinely unique wrinkle: an official government agency formally declaring a case closed while the actual mystery remains completely unresolved. Where Amelia Earhart's disappearance has never received that kind of institutional closure, the U.S. government continues to fund and support new expeditions even decades later, Cooper's file is technically shut, yet the amateur investigation has, if anything, intensified since 2016, with new suspects, new physical evidence claims, and new documentaries appearing well into the 2020s.
There's also a genuinely literal treasure at the center of this case: roughly $194,200 of the original ransom has never been recovered, a detail that has turned parts of the Pacific Northwest into an active, if far less organized, echo of the physical treasure hunts CurioLink covered in its Legendary Lost Treasures series. That combination, real missing money plus a permanently open identity question, sets up a useful contrast with this series' next entry. The Franklin Expedition spent over 160 years as history's most famous unsolved Arctic disappearance, until physical shipwrecks, not fresh testimony or coded letters, finally broke the case open in 2014 and 2016. Whether Cooper's identity will ever see a comparable breakthrough remains, like so much else about the case, entirely unknown.
Frequently Asked Questions
Who was D.B. Cooper?
D.B. Cooper is the name given to an unidentified man who hijacked a Northwest Orient Airlines flight on November 24, 1971, extorted $200,000 in ransom, and parachuted from the plane over southwest Washington, never to be found.
Did D.B. Cooper survive the jump?
It's unknown. Most investigators consider it more likely he died given the extreme conditions, remote terrain, and his equipment, though the absence of any recovered body has kept the survival theory alive among some researchers.
Was any of the ransom money ever found?
Yes, partially. In 1980, an eight-year-old boy found $5,800 in deteriorated bills along the Columbia River, later confirmed to match the ransom's serial numbers. No further money has ever surfaced.
Is the D.B. Cooper case still being investigated?
The FBI formally closed its active investigation in July 2016, though independent researchers and amateur investigators have continued pursuing new leads and suspects since then.
Has D.B. Cooper's real identity ever been confirmed?
No. Numerous suspects have been proposed over the decades, including individuals named in family testimony and physical evidence claims, but none has been definitively confirmed as the hijacker.
