A NEW Netflix docu-series has examined the decades-old mystery of what happened to a hijacker who stole $200,000 and jumped out of a plane 10,000ft in the air.
DB Cooper: Where Are You?! takes a fresh look at the prime suspects believed to be the robber and explores what could have happened next.
The 1971 case remains the only unsolved airplane hijacking in US history
On November 24, a man - who known as Dan or DB Cooper - threatened to detonate explosives unless he was given $200,000 (£168,000).
The brave crew, from the flight between Portland, Oregon and Seattle, Washington, managed to negotiate the passengers being let off before they took to the skies again with the robber.
Cooper demanded the money in cash, four parachutes and to be flown to Mexico City - but while flying over southwestern Washington, he leapt out of the plane from 10,000ft.
The hijacker was never identified, his whereabouts remain a mystery and most of the cash has never recovered - to this day FBI remain baffled over the exact truth of what happened.
The DB Cooper case has been reexplored in the four-part Netflix doc and now, we look back at the suspects.
Suspect 'hid identity but confessed on deathbed'
With no trace of Cooper's body since, hundreds of theories have emerged over the years - along with a stream of suspects.
Previously, the BBC documentary The Hijacker Who Vanished: The Mystery Of DB Cooper looked at the story of one man called Duane Weber.
His wife, Jo Weber, revealed she was married to him for almost 20 years, until his death in 1995 - but they rarely spoke about his past before they met, in 1978, seven years after the hijacking.
However, on his deathbed he changed Jo's life forever when he said he “wanted to tell her a secret”.

Much to Jo's bewilderment, she claimed he began repeatedly muttering about "jumping out of a plane". She then said he added to her: “I’m Dan Cooper."
"Those were his last words, except I love you," she said.
She began to piece together memories from their marriage, that had meant nothing to her at the time.
They included visiting a river once where some of the money was later found, and seeing her husband disappear for several hours, before returning "dirty" as if he'd been "digging".
She also recalled him throwing a bag in to the water on another occasion and watching it float off, but she had assumed it was trash at the time.
No strong evidence has ever connected Duane to the crime.
