The Hijacking of Northwest Orient Flight 305

Sam Shortly before Thanksgiving in 1971, a man bought a one-way plane ticket under a false name, and by that evening had vanished from a moving aircraft with a bag of cash, leaving behind one of the only unsolved hijackings in American history.

Sam It started on the afternoon of November 24th, 1971, at the Northwest Orient counter in Portland, Oregon. A man calling himself Dan Cooper paid cash for a ticket to Seattle on Flight 305. He was quiet, dressed in a business suit with a black tie, and the FBI later described him as a white male in his mid-forties, about six-foot-one, with brown eyes and dark hair combed to one side. Once aboard the Boeing 727, which was only about a third full, he ordered a bourbon and soda while the plane waited to take off. It departed on schedule, at 2:50 p.m.

Sam Shortly after takeoff, Cooper passed a note to Florence Schaffner, the flight attendant seated nearest him. She assumed it was a lonely businessman passing along his phone number and dropped it into her purse unopened. Cooper leaned over and told her to read it — he had a bomb. He opened his briefcase just enough to show her wires and what looked like cylinders. He had her copy his demands onto a fresh sheet in her own handwriting, so nothing in his writing would be left behind: two hundred thousand dollars in cash and two sets of parachutes, waiting when the plane landed in Seattle. Everyone who read the note later agreed on one phrase in it — a warning against "no funny business."

Sam With that note delivered, the plane didn't head straight for Seattle. It circled over Puget Sound for roughly two hours while police and the FBI scrambled to put together what Cooper wanted. Agents pulled the ransom together from banks around Seattle — ten thousand twenty-dollar bills, most carrying serial numbers starting with the letter "L," tying them to the Federal Reserve Bank of San Francisco. Before handing the money over, agents photographed every single bill on microfilm, bill by bill, so each one could be traced later if it ever turned up.

Sam The parachutes were the harder ask. Military personnel at McChord Air Force Base first offered Cooper standard-issue chutes, and he turned them down — he wanted civilian equipment, with ripcords he could pull by hand himself. By asking for two full sets rather than one, he left the impression he might take a hostage down with him, which discouraged anyone from quietly supplying gear that wouldn't actually open. While all this was arranged, flight attendant Tina Mucklow sat beside him for the rest of the flight, passing messages between Cooper and the cockpit.

Sam Word came through to Cooper at 5:24 p.m. that his demands had been met, and at 5:39, well after dark, the plane touched down at Seattle-Tacoma Airport. A Northwest Orient operations manager met the aircraft and handed the money and parachutes over to Mucklow. With the ransom in hand, Cooper let all thirty-five passengers and two of the flight attendants leave the plane. He kept the pilots, the flight engineer, and Mucklow aboard, had the aircraft refueled, and ordered it pointed toward Mexico City, with a planned stop in Reno.

Sam He didn't let the crew fly normally, either. His instructions kept the plane under ten thousand feet, moving slower than two hundred knots, cabin unpressurized, flaps down, landing gear extended the whole way — conditions that made the aircraft fly more like a glider forced low and slow than an airliner on a long-haul route.

Sam Somewhere between Seattle and Reno, a little after eight o'clock that night, Cooper did what no one on that flight expected him to survive doing. He lowered the rear airstairs and jumped out into the dark with two parachutes — one of them, it turned out, sewn shut and useless, meant only for training — and the ransom money tied into a bag with cord cut from a spare chute. The crew up front felt the tail of the plane shift around 8:13 p.m., which investigators came to treat as the moment he went out the back.

Sam He was thought to have gone down somewhere near the Oregon-Washington line, close to the town of Ariel, Washington, over rugged, forested terrain along the Lewis River. One account of that night put the wind at well over two hundred miles an hour relative to his fall, with a parachute that gave him no way to steer it. The pilots brought the plane down safely afterward. Cooper did not reappear — not that night, and not for the rest of the search that followed.

Sam Within hours of that missing tail section, the response built into something closer to a small military operation. Jets and a helicopter were already shadowing the plane, and a C-130 cargo aircraft joined the chase, tracking the 727 as it limped on toward Reno with its stairs still down.

Sam Days later, the military formally joined the search on the ground, and close to a thousand troops combed the forests near Ariel on foot and by air, looking for a man, a parachute, or a body in terrain thick enough to swallow all three.

Sam Investigators even sent the 727 itself back up, stairs lowered, dropping weighted sandbags over the ocean to see how long it would take something that size to fall and hit the water — an attempt to work backward to the exact second Cooper had gone out the door.

Sam The Air Force contributed an SR-71 spy plane, flown along the route to photograph the whole corridor from above. None of it turned up so much as a scrap of silk or a footprint, and the search that had opened with such force closed without a body, a parachute, or the money in hand.

Sam The bureau gave its investigation a name, NORJAK, short for Northwest Hijacking, and by its own account the case became one of the longest and most exhaustive in its history. Over the decades that followed, agents would work through more than eight hundred possible suspects.

Sam What they did pull from the plane itself was modest but specific: a black clip-on tie, a small mother-of-pearl tie clip, a single hair caught on the headrest where Cooper had sat, and eight cigarette butts, Raleigh brand, filter-tipped, left in the armrest ashtray. Years later, forensic work on that tie would yield a DNA sample, though it would take decades for anyone to try matching it to a name.

Sam One more piece turned up far from the plane. In November 1978, a deer hunter working near a logging road east of Castle Rock, Washington — squarely inside the suspected flight path — found a placard giving instructions for lowering a 727's rear airstairs. Apart from the ransom money itself, it remains the only other physical trace anyone has ever recovered.

Sam Before any of that could be made sense of, copycats started appearing. Cooper's method — a note, a bomb threat, a demand for cash and parachutes, a jump from the rear stairs — got repeated by other hijackers in the months that followed, enough of them that people started calling it the Cooper pattern.

Sam The most serious of these came less than five months later. On April 7th, 1972, a man using the alias James Johnson boarded United Airlines Flight 855 during a stopover in Denver — another Boeing 727 fitted with the same rear airstairs. He demanded half a million dollars and four parachutes, backed by a threat of violence, and jumped from the plane over Utah using his own gear.

Sam He was arrested soon after, and the FBI quickly connected the dots: the method was too close to Cooper's to be coincidence. The man was Richard Floyd McCoy Jr., a Vietnam veteran, a National Guard helicopter pilot, and an experienced skydiver — someone who, on paper, looked far more capable of surviving that kind of jump than Cooper ever had.

Sam For a while, investigators strongly suspected they had their man. But McCoy was eventually ruled out, chiefly because he didn't match the physical description two flight attendants had given of Cooper, along with other reasons the bureau cited at the time.

Sam McCoy went to prison for the Denver hijacking, and that was not the end of his story. He fashioned a fake gun, used it to escape custody, and on November 9th, 1974, was killed in a shoot-out with law enforcement — closing out his own case well before the Cooper question around him ever reopened.

Sam While McCoy's case was unfolding, the bureau's picture of Cooper himself kept shifting. Early on, agents assumed he knew both the aircraft and the terrain intimately, and guessed he might have served as a military paratrooper, someone trained for exactly this kind of jump.

Sam That assumption didn't hold. Investigators eventually concluded Cooper probably wasn't an experienced skydiver at all — the jump itself had been far too reckless for someone who knew what he was doing.

Sam Ralph Himmelsbach, the agent who led the early NORJAK effort and later wrote a book about the case, came to doubt whether Cooper had lived through the fall at all. Himmelsbach's view was that a man dropped blind into that terrain, in those winds, with no way to control where he landed, had little chance of walking away from it.

Sam For nearly a decade after that, the case went cold in the truest sense. Then, on February 10th, 1980, an eight-year-old boy named Brian Ingram was smoothing sand for a campfire on the Washington side of the Columbia River, at a spot called Tina Bar, when his arm turned up something buried just beneath the surface.

Sam In his own words, he raked his hand along the sand and felt something "fluffed up" underneath, and uncovered three bundles of money lying just below the surface. The bills had rotted and crumbled from years in the damp ground, but they were still cinched together with their original rubber bands — two packets of a hundred twenty-dollar bills each, and a third of ninety, all in the same order they'd been handed to Cooper on the tarmac.

Sam FBI technicians matched the serial numbers against the microfilm record made the night of the hijacking, and confirmed it beyond doubt: this was ransom money. It was the bureau's first real clue since the night Cooper vanished, and arguably it remains the best one anyone's ever produced.

Sam But Tina Bar sat about nine miles downstream from Vancouver, Washington, and roughly twenty miles southwest of Ariel — far outside where investigators had always assumed Cooper came down. That gap reopened the whole question of where he'd actually landed, splitting researchers into two camps: one side argued the cash had simply washed down the Columbia's tributaries from somewhere near the original jump zone, a theory nicknamed the "Washougal Washdown," while the other side argued the FBI's original flight-path math had been wrong from the start, and Cooper had come down much closer to the river than anyone had calculated.

Sam After the money surfaced, the names kept coming — amateur investigators, family members, retired agents, each convinced they'd solved it, none of them ever confirmed. Richard Floyd McCoy, the copycat hijacker himself, got a second look in a 1991 book by a retired federal probation officer,, and that theory would come back again decades later.

Sam Other names followed their own, separate paths into the story. A Northwest Orient mechanic and former military parachutist named Kenneth Christiansen was named by his own brother in 2003, after watching a documentary, and became the subject of a private investigator's book years later. A Vietnam-era helicopter pilot named Robert Rackstraw was pushed hardest by a television producer who argued the FBI had quietly identified him and covered it up — a claim that led to a federal lawsuit demanding the bureau's files, and which Rackstraw denied through his lawyer right up until his death in 2019.

Sam A University of Washington librarian and transgender aviator named Barbara Dayton was named by friends and family after she allegedly told them outright that she was Cooper. A career burglar and forger named Duane Weber confessed to his wife from a hospital bed days before he died in 1995, though fingerprints and DNA recovered from the plane didn't match his. A logger from Oregon named L.D. Cooper was named by his niece, who recalled him coming home injured around Thanksgiving of 1971. And a man named Walter Reca was named after his own death, by a writer who said Reca had confessed to him years earlier. None of these claims has ever been substantiated, and the bureau has never endorsed any of them.

Sam In 2009, a group calling itself the citizen sleuths started reexamining the physical evidence with tools that hadn't existed in 1971, and the FBI let them in to see the full archive. Among their findings was something that complicated the money's own story: microscopic algae called diatoms, which only bloom in spring, were found on the bills recovered at Tina Bar — and only one season's worth was on them, suggesting the cash hadn't gone into the water the night Cooper jumped at all, but sometime later. Separate forensic work around the same period found particles of pure titanium embedded in the hijacker's clip-on tie, the kind of trace that pointed toward work in a chemical plant or a company that handled titanium — fuel for speculation about ties to the aerospace industry, Boeing included.

Sam None of it added up to a name. On July 12th, 2016, forty-five years after the jump, the FBI closed its active investigation. The Seattle agent in charge told reporters it was simply time, because there wasn't anything new left to chase, and the bureau's statement made clear that no tip and no new technology had ever produced what it needed — a definitive identification. It left one door open, for physical evidence tied specifically to the parachutes or the money, and nothing else.

Sam The bureau's closure didn't end the legal pressure. Thomas Colbert and his attorney, Mark Zaid, pressed forward with their federal lawsuit, filed that September, demanding the FBI release its files on Robert Rackstraw under the Freedom of Information Act.

Sam That push produced something new the following year. In 2017, the FBI released a set of letters the hijacker had allegedly mailed to newspapers in the days right after the hijacking, and amateur investigators pored over the wording and phrasing for anything that might point toward a name.

Sam Closure at the bureau didn't mean the case went quiet elsewhere. Independent researchers kept working through the back half of the decade, and in 2021, marking the hijacking's fiftieth anniversary, a gathering called Coopercon convened in Vancouver, Washington, drawing a retired FBI agent, a passenger who had sat near Cooper, Brian Ingram all grown up, and dozens of researchers who'd built careers chasing the case.

Sam Researcher Eric Ulis took his own line of inquiry back to the riverbank itself, organizing new ground searches at Tina Bar, sifting the sediment there for anything that might explain how the cash ended up buried so far from where investigators had long assumed Cooper came down.

Sam Then the case found new physical evidence of the kind the FBI had said it would still act on. A retired commercial pilot and YouTuber turned up a parachute rig in an outbuilding on McCoy family property in North Carolina - the family of Richard Floyd McCoy, the copycat hijacker whose own case had closed with his death decades earlier.

Sam He called it a one-in-a-billion piece of evidence, and the claim was specific: the rig carried modifications that aviation investigators said matched the chutes supplied to Cooper on the tarmac in Seattle. McCoy's son went public backing the theory, saying he believed his father had been the hijacker all along, citing an account he attributed to his late mother.

Sam The FBI took the claim seriously enough to act on it directly. Agents seized the parachute and related items in 2024, returned to the McCoy property for a more thorough search, and began forensic testing that would stretch on for two years.

Sam That testing ended in December 2025, when the bureau returned the parachute to McCoy's son. No findings were disclosed — nothing about what the material was, what condition it was in, or whether any DNA recovered from it had been compared against the profile pulled from Cooper's clip-on tie years before.

Sam As of the most recent reporting, no result from that testing has ever been made public, and the FBI has said nothing further about the McCoy rig since handing it back.

Sam More than fifty-four years on, the case sits exactly where the bureau left it when it closed the file: identity and fate both unproven, the door open only to new physical evidence tied to the parachutes or the ransom cash, nothing else accepted.

Sam No suspect has ever been charged. No body has ever been found. The only confirmed trace of the ransom remains the roughly $5,800 Brian Ingram dug out of the sand at Tina Bar in 1980, and every other lead — Rackstraw, Christiansen, Dayton, Weber, L.D. Cooper, Reca, McCoy — remains exactly that: a lead, proposed by someone with a reason to believe it, never proven.

Sam The case keeps generating its own momentum anyway — books, documentaries, a Netflix series among them — and this November, D.B. Cooper Con 2026 is set to gather researchers and enthusiasts once more at the Kiggins Theatre, fifty-five years into an effort that has outlasted the agents, the suspects, and most of the people who were on that plane.

Sam That's where the story stands: a man walked off a moving aircraft into a storm with a bag of cash, and the only pieces anyone has ever recovered are a tie, a placard, and some rotting twenties in a riverbank. Everything else is still just a theory looking for proof.

Sam Before I go, a word on how this episode came together: the voice you're hearing is synthetic, this show is AI-generated, and the facts behind it come from source reporting whose authors have no connection to this production. Everything today came from reporting by the FBI's own case files and public statements, Wikipedia, NBC News, Fox News, Cowboy State Daily, ScreenRant, and the D.B. Cooper Forum. Thanks for listening.
