On this day in 1971, an unassuming man wearing a business suit who appeared to be in his mid-40s hijacked and threatened to blow up a Northwest Orient Airlines plane traveling from Portland, Ore., to Seattle if he did not get four parachutes and a $200,000 ransom.

When the plane landed in Seattle, the suspect, known only as Dan Cooper or D.B. Cooper, allowed the passengers and two flight attendants to get off the plane, and the officials handed over the money, in $20 bills, and the parachutes.

This August, a woman reignited the 40-year-old cold case when she claimed her uncle, Lynn Doyle Cooper, was the infamous skyjacker.
