2. An Unsolved Mystery

On November 24, 1971, in what was perhaps the most sensational aircraft hijacking in aviation history, a man known as D.B. Cooper hijacked a Boeing 727 en route from Portland, Oregon, to Seattle, Washington. After boarding the plane, lighting a cigarette and ordering a bourbon and soda, the sharply dressed Cooper handed a note to his stewardess notifying her that he had a bomb and was hijacking the plane. 

He demanded $200,000 and four parachutes, which he received after the plane’s arrival in Seattle. After the other passengers deplaned, the plane took off again and Cooper ordered the remaining crew to get into the cockpit. When the plane landed in Reno, Cooper and the cash were gone.
