49 Years After D.B. Cooper Vanished Into Thin Air, A Scientist Uncovered A Compelling New Clue

“I have a bomb.” It’s 1971, and those four fearsome words have just been scrawled on a note and handed to flight attendant Flo Schaffner. The man who wrote them – a passenger on Northwest Orient Airlines Flight 305 – also reveals a briefcase seemingly filled with dynamite. Terrified, Schaffner sees no option but to help him secure a ransom of $200,000 and four parachutes. And when the cash is delivered, the thief makes a daring mid-air leap from the plane – never to be seen again. It’s an incredible story, and the jaw-dropping hijack baffled experts and investigators the world over. But now, almost 50 years later, important new evidence has allowed researchers to crack a crucial component of the D.B. Cooper case.
