D.B. Cooper: He Hijacked a Plane, Jumped Into a Storm, and No One Ever Found Him

The night before Thanksgiving, 1971. A calm, polite man in a business suit hands a flight attendant a note saying he has a bomb. He asks for $200,000 in twenty-dollar bills and four parachutes, releases all thirty-six passengers once his demands are met, and then, somewhere over the dark forests of southwest Washington, lowers the rear stairs of a Boeing 727 and jumps into freezing rain at 200 miles an hour. He is never seen again. No body, no parachute, no trace. Fifty years later, the FBI has investigated more than a thousand suspects and closed the case unsolved. They call him D.B. Cooper, though that wasn't even the name he gave.

This week on Mugshot Mysteries, Kathryn and Gabriel take a break from the bodies for the only unsolved air piracy case in American history, and have a genuinely good time doing it.

We walk the hijacking minute by minute: the bourbon and the obscure Raleigh cigarettes, the flight attendant who pocketed his note assuming it was his phone number, the briefcase of red cylinders and wires the FBI later suspected was a fake, and the eerie courtesy that defined the whole ordeal, this was a man who offered to order meals for the hungry crew mid-hijacking. We get into the clever details: why he demanded twenties, why four parachutes was a stroke of self-protective genius, and how the 727's rear airstairs (since disabled by a device now literally called the "Cooper vane") made his escape physically possible.

Then we open the floodgates on theories, because that's the fun of this one. The 1980 discovery of $5,800 of the ransom by a boy on the Columbia River, and why those intact rubber bands bother investigators to this day. The leading suspects, the Boeing-savvy Kenneth Christiansen, the copycat hijacker Richard McCoy, and the deathbed confessors, weighed against the physical descriptions and the limits of the evidence. The disgruntled-Boeing-employee theory, the dying-man theory, the intelligence-operative theory, and the genuinely intriguing possibility that Cooper was a woman in disguise, including the Barbara Dayton claim. Along the way we have an honest conversation about why eyewitness memory is so shaky, why America keeps turning outlaws into folk heroes, and how this one stunt changed air travel forever, metal detectors, the end of walk-on-with-anything flying, and fifteen copycat attempts in 1972 alone.

No murder this time. Just the last great American mystery, and two hosts cheerfully refusing to agree on how it ends.

This is D.B. Cooper.
