On July 12, 2016, the FBI finally closed the files on one of its most famous unsolved cases. They called it the NORJAK case — short for Northwest Hijacking — but you probably know it by the name given to the hijacker,
D. B. Cooper. Most people are familiar with the basic facts: that in 1971, a man hijacked an airliner, demanded and received cash and a parachute, and jumped out the plane’s back door over the Pacific Northwest and was never caught or identified. Whether he got away clean, or was killed in the attempt, could never be determined. Even though the D. B. Cooper case continues to capture the public’s imagination, there is a lot of fact and fiction unknown to many fans.
On the afternoon of November 24, 1971, a man who looked mid-40ish, wearing a business suit, walked up to the counter of Northwest Airlines in Portland, Oregon. Using the name Dan Cooper, he bought a $20 one-way ticket to Seattle, Washington. He was the second-to-last person to board the plane, and while waiting for takeoff, he ordered and drank a bourbon and soda — unfortunately spilling half of it. Once airborne, he handed flight attendant Florence Schaffner a note, which said something to the effect of “I have a bomb which I will use if necessary, this is a hijacking, please sit next to me.” She showed it to fellow flight attendant Tina Mucklow and to the pilots. Cooper then asked for the note back, which is why its exact wording is not known.
Schaffner took the empty seat next to him as ordered and he opened a briefcase, and showed her what she described as red sticks with a battery and wires. He then dictated to her the following demands:
Take this down. I want $200,000 by 5:00 PM in cash. Put it in a knapsack. I want two back parachutes and two front parachutes. When we land, I want a fuel truck ready to refuel. No funny stuff, or I’ll do the job.
Schaffner conveyed this information to the pilot. Almost nobody on the plane knew anything unusual was happening; the whole episode was handled discreetly. Cooper added that if these instructions were followed, he would safely release everyone on the plane, except for the flight crew.
The airline agreed and contacted the FBI for assistance making the exchange safely. The FBI collected the money from the Seattle First National Bank. Some FBI records say they used a Recordak high-speed microfilm machine to image the serial numbers of all the bills; other records say the bank had the money on hand with its serial numbers already recorded. The airline got on the phone and collected the four parachutes from local contacts. Two hours later, the exchange had been successful, and the plane taxied for takeoff, fully refueled.
Cooper instructed that the plane was to fly a specific route, from Seattle to Portland, to Medford, to Red Bluff, and then to Reno, all while staying below 10,000 feet and keeping the flaps and landing gear down. The plane was a Boeing 727, featuring the nifty “Airstair” rear access stairway under the tail. Cooper had released two of the flight attendants along with the passengers, but had kept Mucklow on board so she could show him how to operate the Airstair.
Frustrated that the money had not been delivered in a knapsack as he’d requested, Cooper began cannibalizing one of the parachute’s cords to do what Mucklow thought was tying the bundles of money to himself. About a half hour after takeoff, Cooper ordered Mucklow up to the cockpit with the pilots and closed the door, ordering them not to open it. At 8:13pm, over southern Washington, the pilots got a number of warning lights. The Airstair had been lowered, cabin pressure had dropped, and the cabin temperature fell sharply — it was -7ºF outside. Not knowing whether Cooper had jumped or not, they continued on to Reno as ordered and landed, causing a nice display of sparks (but no damage) as the Airstair briefly scraped the runway. After receiving no response from Cooper over the intercom, they chanced to open the door, and found him gone; all that remained were his clip-on tie, and a ton of cigarette butts. Nobody would ever see him again.
