In November 1971, a man boarded a commercial flight using the name Dan Cooper.

Shortly after takeoff, he handed a note to a flight attendant.

It stated that he had a bomb.

He demanded 200,000 dollars and four parachutes.

His demands were met.

Passengers were released.

The plane took off again.

Sometime during the flight, he lowered the rear staircase and jumped.

He was never seen again.

No confirmed trace of him was ever found.

More than fifty years later, the identity of D. B. Cooper remains unknown.
