D.B. Cooper: The Hijacker Who Jumped into the Night and Never Landed
On the afternoon of 24 November 1971, the day before Thanksgiving, a quiet man in a dark suit and black tie bought a ticket under the name Dan Cooper and boarded Northwest Orient Flight 305 from Portland, Oregon, to Seattle. Shortly after takeoff he handed a note to a flight attendant. It said, in essence, that his briefcase held a bomb. When she sat beside him, he opened the case just enough to show wires, red sticks and a battery.
His demands were precise: $200,000 in twenty-dollar bills and four parachutes, to be delivered in Seattle. While the plane circled, authorities gathered the money and photographed the bills to record their serial numbers. On the ground, Cooper released all 36 passengers in exchange for the ransom, kept several crew members aboard, and ordered the Boeing 727 refueled for a flight toward Mexico City — flown low and slow, with the landing gear down, flaps at fifteen degrees, and the rear airstair unlocked.
Somewhere over the rugged forests of southwest Washington, at around 8:13 p.m., the aircraft's tail dipped slightly. Cooper had walked down the aft stairs and jumped into a freezing, rain-lashed night with the money tied to his body. When the plane landed in Reno, the cabin was empty. He was never seen again.
The FBI launched one of the longest manhunts in its history, code-named NORJAK. Over 45 years, agents considered roughly a thousand suspects — army veterans, pilots, con men, a purser named Kenneth Christiansen, a copycat hijacker named Richard McCoy — without ever making the case. Even the name the world knows is an accident: a wire-service error turned "Dan Cooper" into "D.B. Cooper," and the mistake stuck.
Then, in February 1980, the story took its strangest turn. An eight-year-old boy named Brian Ingram, digging a fire pit on a Columbia River sandbar known as Tena Bar, uncovered three decaying bundles of twenty-dollar bills — $5,800 whose serial numbers matched the ransom. Instead of solving the mystery, the find deepened it: later analysis of diatoms, microscopic algae on the bills, suggested the money entered the water months after the November hijacking, not on the night of the jump.
In July 2016 the FBI formally closed its active investigation, leaving the case what it remains today: the only unsolved commercial airliner hijacking in American history. The core questions are untouched by half a century of sleuthing. Did Cooper survive a night jump into a storm, in loafers and a business suit? Who was the polite man in seat 18? And how did $5,800 of his ransom end up in the sand of Tena Bar — miles from the estimated drop zone — while the other $194,200 has never surfaced anywhere on earth?
