DB Cooper and Eric Ulis
On Thanksgiving Eve 1971, a man calling himself Dan Cooper skyjacked a Northwest Orient flight traveling from Portland to Seattle.
Upon landing in Seattle, Cooper ransomed the passengers for $200,000 and four parachutes. He then directed the jet to take-off and head to Mexico City by way of Reno for a fuel stop.
Approximately 36 minutes after departing Seattle, somewhere just north of Portland, Cooper parachuted out of the back of the jet never to be seen or heard from again.
Eric Ulis is one of the world's leading DB Cooper experts. He has researched, investigated, searched for and extensively written about the case--the only unsolved skyjacking in United States history.
