DB Cooper skyjacked plane 47 years ago Saturday

The FBI closed the DB Cooper case in 2016 unsolved.

November 24 marks 47 years since the world’s most infamous skyjacking that happened in our backyard.

On Thanksgiving Eve 1971, a man aboard a Portland to Seattle flight told the stewardess he had a bomb in his suitcase. He demanded $200,000 and four parachutes, which the FBI delivered when the plane landed at Sea-Tac Airport. The plane was refueled at his request and took off for Mexico.

When the plane was airborne again, headed south, the man, who became known as DB Cooper, jumped off the back staircase of the Boeing 727 into the frigid night sky.

In 2009, a band of amateur scientists were selected by the Seattle FBI to look for clues in the cold case.

The FBI closed the case in 2016 unsolved. The bureau was clearly frustrated by the lack of credible leads.

In January 2017, the team’s analysis pointed to Cooper possibly being a Boeing employee.

A year later, a team of filmmakers said they thought they had discovered Cooper's identity based on a letter he was believed to have written to several news outlets. However, that person was already investigated by the FBI in the later 1970's.

The team continues to investigate, even though the FBI is unlikely to re-open the case.
