A man in a suit.
A briefcase bomb.
A ransom demand for $200,000.
And then—he vanished into the storm.

On November 24, 1971, a man calling himself Dan Cooper boarded Northwest Orient Flight 305 from Portland to Seattle. Calm, composed, and oddly polite, he would soon become the center of the only unsolved airplane hijacking in U.S. history.

In this episode of Disturbing History, Brian walks through every twist and contradiction in the D.B. Cooper mystery—from the dramatic mid-air jump into darkness, to the strange discoveries in the wilderness, to the endless stream of suspects and theories that still haunt investigators to this day.

 Was Cooper a rogue intelligence agent?

A Vietnam veteran with nothing to lose?

Or did he disappear with the money and live the rest of his life in quiet victory? One man walked onto a plane.
No one ever saw him again.
But the myth he left behind has never stopped flying.Some legends fade with time.
Others jump into the unknown—and never land.
