Finding DB Cooper: Chasing the Last Lead in America's only Unsolved skyjacking

The day before Thanksgiving in 1971, a man wearing a business suit and carrying a briefcase boarded a Northwest Orient flight in Portland, bound for Seattle. Claiming to have a bomb, the skyjacker held the passengers and crew for $200,000 ransom while demanding four parachutes. After getting his money and parachutes in Seattle, the Boeing 727 took off, going south to Reno. About a half an hour later, the mysterious hijacker jumped out the back of the aircraft, and disappeared forever. "Norjak" as the FBI would later label it, would become the only unsolved skyjacking in American history. Almost forty years later, new evidence was uncovered when the case was finally opened up to a select group of amateur sleuths. Now, their findings have confirmed one of the scores of stories surrounding the hijacking. Join in the race to find out who D.B Cooper was, following up on the Last Lead in one of America's great unsolved mysteries.
