An unidentified man hijacked a Boeing 727 that was on its way from Seattle , Washington , to Portland , Orgeon on Nov. 24, 1971 .

His demands were that upon landing in Seattle , he wanted four parachutes and $ 200,000 cash.

The hijacker called himself Dan Cooper , but many media reports out of the U.S. mistakenly referred to him as D.B. Cooper and that name stuck.

The FBI kept an open file on the case for 45 years and the case was closed in July 2016 .
