The Mystery of D.B. Cooper

A man using the fake name Dan Cooper hijacked a plane in 1971. Media mistakenly

called him D.B. Cooper, which became famous. He was described as calm,

polite, and wearing a suit and sunglasses. He told a flight attendant he had

a bomb. He demanded $200,000 and four parachutes. He let the passengers go after getting

the money in Seattle. He jumped out of the plane with a parachute at night. He was never found,

and the case is still unsolved. He became a famous mystery and part of American pop

culture.
