On November 24, 1971—Thanksgiving Eve—a man carrying a black attaché case and a brown paper bag walked up to the Northwest Orient Airlines flight counter at Portland International Airport. He used cash to purchase a one-way ticket for Flight 305, a short 30-minute hop north to Seattle.
On his ticket, he wrote a name that would soon echo through American history: "Dan Cooper".
Eyewitnesses would later describe him as a calm, well-dressed man in his mid-40s, sporting a business suit, a white shirt, a thin black tie, a black raincoat, and brown shoes. He boarded the Boeing 727, took seat 18-E in the very last row, and ordered a bourbon and 7-Up.
Shortly after takeoff, Cooper handed a note to Florence Schaffner, a flight attendant sitting in a jump seat directly behind him. Accustomed to lonely businessmen passing their telephone numbers, Schaffner dropped the note unopened into her purse.
Cooper leaned closer and whispered: "Miss, you'd better look at that note. I have a bomb."
When she opened the note, written in neat felt-tip block letters, it read: "Miss—I have a bomb in my briefcase and want you to sit by me." Shaken but professional, Schaffner sat next to him and quietly asked to see the device. Cooper opened his briefcase just enough for her to glimpse a terrifying arrangement of red cylinders—which she assumed to be dynamite—wired to a large battery.
The Demands and the Standoff
Cooper closed his briefcase and issued a precise set of demands: $200,000 in negotiable American currency stuffed into a knapsack, and four parachutes (two main/back parachutes and two front/reserve parachutes). By demanding four parachutes, Cooper masterfully forced the FBI and local authorities to provide fully functional equipment, implying he might force a flight crew member or a passenger to jump with him as a hostage.
For two agonizing hours, Flight 305 circled the Puget Sound in a holding pattern while the Seattle Police Department and the FBI scrambled to gather the cash and the parachutes. While circling, Cooper remained surprisingly calm and polite. Flight attendant Tina Mucklow, who sat by him as a liaison, noted that he wasn’t cruel or nasty. He even joked about having a general "grudge" and offered her a cigarette.
At 5:46 PM, the plane finally landed at Seattle-Tacoma International Airport. In exchange for the $200,000—comprising 10,000 unmarked twenty-dollar bills—and the four parachutes, Cooper allowed all 36 passengers to safely disembark.
However, things didn't go entirely according to Cooper's plan. He grew impatient when a refueling issue delayed the flight, complaining that the money had been delivered in a standard canvas bank bag rather than the knapsack he requested. To solve his transportation problem, Cooper pulled out a pocket knife, aggressively cut the canopy fabric from one of the reserve parachutes, and used the remaining shroud cords to tie his stolen money bag tightly shut. He stuffed some of the currency into an empty parachute bag.
The Midnight Leap
With only Cooper and a skeleton crew of five remaining on board, the Boeing 727 took off again around 7:40 PM, ordered to fly toward Mexico City via a refueling stop in Reno, Nevada. Cooper gave strict aerodynamic instructions: fly at a low altitude of 10,000 feet, keep the landing gear and wing flaps deployed, and leave the cabin unpressurized to allow an easy escape.
Cooper ordered Tina Mucklow into the cockpit and told her to pull the partition curtain shut. Before she left, she begged him to take the bomb with him, and he promised he would. As she turned away, she caught one final glimpse of "Dan Cooper" standing alone in the aisle, frantically tying the canvas money bag around his waist.
At approximately 8:00 PM, a warning light flashed in the cockpit. The plane's aft exit door had been opened, and the airstair had been deployed.
Amidst a blinding freezing rainstorm, blinding darkness, and zero visibility, Cooper walked down the extended stairs and leaped into the freezing night sky over the rugged, heavily wooded wilderness of Southwest Washington. He was never seen again.
The Phantom Clues and Shifting Theories
The FBI launched "NORJAK" (short for Northwest Hijacking), an exhaustive, multi-decade investigation that generated an immense case file. Yet, the wilderness refused to yield its secrets.
The physical evidence left on the plane was minimal: Cooper's black clip-on tie, a tie clip, and two of the four parachutes. Investigators discovered he had jumped with the primary parachute and an older, non-steerable reserve chute. Ironically, the second reserve chute he chose had been a non-functional unit used strictly for classroom instruction—it had been deliberately sewn shut. If Cooper had tried to pull that reserve chord in mid-air, it never would have opened.
For years, many experts believed Cooper could not have survived the plunge. He leaped into a pitch-black forest wearing nothing but a business suit and unsuitable footwear, carrying a parachute that couldn't be steered. This grim theory was given a massive boost in 1980 when a young boy vacationing with his family found a rotting, rubber-banded package along the banks of the Columbia River near Vancouver, Washington. Inside was $5,800 of the ransom money, severely degraded by water and sand, but with serial numbers perfectly matching the FBI’s microfilm records. The rest of the $200,000 was never found.
As for his famous moniker, "D.B. Cooper" was actually a complete media myth. In the frantic hours following the skyjacking, a rushed reporter misheard a source and published the initials "D.B." instead of "Dan," creating a legend out of a typo. The FBI did track down and interview a local man named D.B. Cooper, but he was quickly cleared of any involvement.
The Copycat and the Suspicion
The sheer audacity of the crime triggered a wave of copycats, prompting the aviation industry to mandate airport metal detectors and baggage inspections for the very first time.
Among the copycats, one suspect rose above the rest: Richard Floyd McCoy. Less than five months after Cooper’s escape, McCoy pulled off a near-identical hijacking of a commercial airliner and successfully escaped via parachute. The FBI tracked him down, arrested him, and recovered his ransom. Because the methodology was so mirroring, McCoy became an instant favorite suspect among amateur sleuths.
However, the FBI eventually ruled him out. McCoy did not match the distinct, nearly identical physical descriptions provided by Florence Schaffner and Tina Mucklow, and reliable alibis placed him elsewhere during the Thanksgiving Eve flight.
In 2016, citing the need to allocate resources to higher-priority cases, the FBI officially suspended its active investigation into the NORJAK file. To this day, the Cooper case remains the only unsolved incident of commercial air piracy in aviation history. Whether he perished in the freezing mud of Washington or lived out his days spending unmarked cash under a new name, Dan Cooper successfully pulled off the ultimate vanishing act.
