One afternoon a day before Thanksgiving in 1971, a guy calling himself Dan Cooper (the media mistakenly called him D.B. Cooper) boarded Northwest Airlines flight #305 in Portland bound for Seattle.
He was wearing a dark suit and a black tie and was described as a business-executive type. While in the air, he opened his brief case showing a bomb to the flight attendant and hijacked the plane. The plane landed in Seattle where he demanded 200K in cash, four parachutes and food for the crew before releasing all the passengers. With only three pilots and one flight attendant left on board, they took off from Seattle with the marked bills heading south while it was dark and lightly raining. In the 45 minutes after takeoff, Cooper sent the flight attendant to the cockpit while donning the parachute, tied the bank bag full of twenty dollar bills to himself, lowered the rear stairs and somewhere north of Portland jumped into the night. When the plane landed with the stairs down, they found the two remaining parachutes and on the seat Cooper w
On the afternoon of Thanksgiving eve, November 24, 1971, a man carrying a black attaché case approached the flight counter of Northwest Orient Airlines at Portland International Airport. He identified himself as “Dan Cooper” and purchased a one-way ticket on Flight 305, a 30-minute trip to Seattle.
Cooper boarded the aircraft, a Boeing 727-100 (FAA registration N467US), and took A seat In the rear of the passenger cabin. He lit a cigaretteand ordered a bourbon and soda. Eyewitnesses on board recalled a man in his mid-forties, between 5 feet 10 inches (1.78 m) and 6 feet 0 inches (1.83 m) tall. He wore a black lightweight raincoat, loafers, a dark suit, a neatly pressed white collared shirt, a black necktie, and a mother of pearl tie pin.
Flight 305 was approximately one-third full when the aircraft took off on schedule at 2:50 pm, PST. Cooper handed a note to Florence Schaffner, the flight attendant situated nearest to him in a jump seat attached to the aft stair door. Schaffner, assuming the note contained a lonely businessman’s phone number, dropped it unopened into her purse. Cooper leaned toward her and whispered, “Miss, you’d better look at that note. I have a bomb.
The note was printed in neat, all-capital letters with a felt-tip pen. Its exact wording is unknown, because Cooper later reclaimed it, but Schaffner recalled that it indicated he had a bomb in his briefcase, and wanted her to sit with him.Schaffner did as requested, then quietly asked to see the bomb. Cooper cracked open his briefcase long enough for her to glimpse eight red cylinders (“four on top of four”) attached to wires coated with red insulation, and a large cylindrical battery.After closing the briefcase, he dictated his demands: $200,000 in “negotiable American currency”;four parachutes (two primary and two reserve); and a fuel truck standing by in Seattle to refuel the aircraft upon arrival.Schaffner conveyed Cooper’s instructions to the pilots in the cockpit: when she returned, he was wearing dark sunglasses.
The pilot, William Scott, contacted Seattle-Tacoma Airport air traffic control, which in turn informed local and federal authorities.
The 36 other passengers were told that their arrival in Seattle would be delayed because of a “minor mechanical difficulty”.Northwest Orient’s president, Donald Nyrop, authorized payment of the ransom and ordered all employees to cooperate fully with the hijacker. The aircraft circled Puget Sound for approximately two hours to allow Seattle police and the FBI time to assemble Cooper’s parachutes and ransom money, and to mobilize emergency personnel.
Schaffner recalled that Cooper appeared familiar with the local terrain; at one point he remarked, “Looks like Tacoma down there,” as the aircraft flew above it. He also correctly mentioned that McChord Air Force Base was only a 20-minute drive (at that time) from Seattle-Tacoma Airport. Schaffner described him as calm, polite, and well-spoken, not at all consistent with the stereotypes (enraged, hardened criminals or “take-me-to-Cuba” political dissidents) popularly associated with air piracy at the time. Tina Mucklow, another flight attendant, agreed. “He wasn’t nervous,” she told investigators. “He seemed rather nice. He was never cruel or nasty. He was thoughtful and calm all the time.” He ordered a second bourbon and water, paid his drink tab (and attempted to give Schaffner the change), and offered to request meals for the flight crew during the stop in Seattle.
FBI agents assembled the ransom money from several Seattle-area banks—10,000 unmarked 20-dollar bills, most with serial numbers beginning with the letter “L” indicating issuance by the Federal Reserve Bank of San Francisco, and most from the 1963A or 1969 series and made a microfilm photograph of each of them.Cooper rejected the military-issue parachutes offered by McChord AFB personnel, demanding instead civilian parachutes with manually operated ripcords. Seattle police obtained them from a local skydiving school.
At 5:24 pm Cooper was informed that his demands had been met, and at 5:39 pm the aircraft landed at Seattle-Tacoma Airport.
Cooper instructed Scott to taxi the jet to an isolated, brightly lit section of the tarmac and extinguish lights in the cabin to deter police snipers. Northwest Orient’s Seattle operations manager, Al Lee, approached the aircraft in street clothes (to avoid the possibility that Cooper might mistake his airline uniform for that of a police officer) and delivered the cash-filled knapsack and parachutes to Mucklow via the aft stairs. Once the delivery was completed, Cooper permitted all passengers, Schaffner, and senior flight attendant Alice Hancock to leave the plane.
During refueling Cooper outlined his flight plan to the cockpit crew: a southeast course toward Mexico City at the minimum airspeed possible without stalling the aircraft—approximately 100 knots (190 km/h; 120 mph)—at a maximum 10,000 foot (3,000 m) altitude. He further specified that the landing gear remain deployed in the takeoff/landing position, the wing flaps be lowered 15 degrees, and the cabin remain unpressurized.Copilot William Rataczak informed Cooper that the aircraft’s range was limited to approximately 1,000 miles (1,600 km) under the specified flight configuration, which meant that a second refueling would be necessary before entering Mexico. Cooper and the crew discussed options and agreed on Reno, Nevada, as the refueling stop. Finally, Cooper directed that the plane take off with the rear exit door open and its staircase extended. Northwest’s home office objected, on grounds that it was unsafe to take off with the aft staircase deployed. Cooper countered that it was indeed safe, but he would not argue the point; he would lower it himself once they were airborne.
An FAA official requested a face-to-face meeting with Cooper aboard the aircraft, which was denied.The refueling process was delayed because of a vapor lock in the fuel tanker truck’s pumping mechanism,and Cooper became suspicious; but he allowed a replacement tanker truck to continue the refueling—and a third after the second ran dry.
At approximately 7:40 pm, the 727 took off with only Cooper, pilot Scott, flight attendant Mucklow, copilot Rataczak, and flight engineer H. E. Anderson aboard. Two F-106 fighter aircraft scrambled from nearby McChord Air Force Base followed behind the airliner, one above it and one below, out of Cooper’s view.
A Lockheed T-33 trainer, diverted from an unrelated Air National Guard mission, also shadowed the 727 until it ran low on fuel and turned back near the Oregon–California state line.
After takeoff, Cooper told Mucklow to join the rest of the crew in the cockpit and remain there with the door closed. As she complied, Mucklow observed Cooper tying something around his waist. At approximately 8:00 pm a warning light flashed in the cockpit, indicating that the aft airstair apparatus had been activated. The crew’s offer of assistance via the aircraft’s intercom system was curtly refused. The crew soon noticed a subjective change of air pressure, indicating that the aft door was open.
At approximately 8:13 pm the aircraft’s tail section sustained a sudden upward movement, significant enough to require trimming to bring the plane back to level flight. At approximately 10:15 pm Scott and Rataczak landed the 727, with the aft airstair still deployed, at Reno Airport. FBI agents, state troopers, sheriff’s deputies, and Reno police surrounded the jet, as it had not yet been determined with certainty that Cooper was no longer aboard; but an armed search quickly confirmed that he was gone.
After hijacking an aeroplane and extorting $200,000 from the FBI, DB Cooper coolly made his escape via parachute.
Many suspect he died on the descent. That theory was strengthened in 1980 when an 8-year-old boy stumble open three wads of rotting $20 bills with serial numbers matching the cash given to Cooper.
However, his body was never found leading to countless theories about who he was and what might have happened.
In 2016, when the FBI closed the D.B. Cooper case, Mucklow says she felt sad. She wished they had found the hijacker and charged him. “He was a criminal,” she says, “Who was not only threatening my life, but the lives of all those innocent people on that flight.” At the same time, she understood the decision. “I recognize that it was probably the right thing to do given the amount of time [that has passed] and knowing all the needs of our world today.”
Today, Mucklow is 71 and recently retired, waiting for the Covid-19 pandemic to subside so she can resume volunteering at a soup kitchen, spend time with friends, and go out to eat.
