Unmasking D.B. Cooper: An AI-Driven Framework for Solving America's Last Great Skyjacking Mystery

By Richard Murch

So the mystery of the highjacker began, and now we have AI to look at all the facts and make some interesting conclusiions

On the afternoon of November 24, 1971, a man in a dark business suit paid cash for a one-way ticket from Portland to Seattle and boarded Northwest Orient Flight 305, a Boeing 727, as Dan Cooper. Airport screening did not yet exist, so he was never asked for identification and left no paper trail beyond the ticket itself.

He carried a briefcase and a paper sack, took a seat toward the rear of the cabin, and ordered a bourbon and soda.

The absence of identification is the case's original wound. Everything investigators know about the man's name is a fiction he supplied, later garbled by the press into the enduring alias - D. B. COOPER.

Roughly midway through the short flight, Cooper passed a note to a flight attendant, told her quietly that he had a bomb, and opened the briefcase to reveal what appeared to be wires and cylinders. His demands were specific and professional: two hundred thousand dollars in twenty-dollar bills, four parachutes, and a fuel truck standing by in Seattle. He wanted the aircraft refueled and flown toward Mexico City.

The request for four parachutes, rather than one, was itself a tactic. It implied that Cooper might force a hostage to jump with him, which discouraged authorities from supplying a sabotaged or non-functional chute. This detail is frequently cited as evidence of planning and composure rather than improvisation.
