The flight attendant informed the pilot of Cooper's demands, and the plane was diverted to Seattle-Tacoma International Airport. After the plane landed, Cooper released the passengers in exchange for the money and parachutes. He then ordered the pilots to fly to Mexico City.
Somewhere between Seattle and Reno, Nevada, Cooper lowered the rear stairs of the plane and jumped out with the money. He has never been seen or heard from since.
The FBI launched a massive manhunt, but Cooper was never found. The case remains one of the greatest unsolved mysteries in American history.
There are many theories about what happened to Cooper after he jumped from the plane. Some believe that he survived the jump and escaped with the money. Others believe that he died in the jump or landed in a remote area and died of exposure.
In 1980, a young boy found a rotting package containing $5,800 of the ransom money on a beach in Washington state. The rest of the money has never been found.
The FBI has investigated over 1,000 suspects in the D.B. Cooper case, but none of the leads have panned out. The case remains open, and the FBI is still seeking information about Cooper's identity and whereabouts.
What happened to D.B. Cooper?
That is the question that has captivated people for decades. There are many theories, but no one knows for sure.
Some believe that Cooper was a professional skydiver who knew exactly what he was doing. They point to the fact that he jumped at night in bad weather, which would have made it difficult to survive.
Others believe that Cooper was a desperate man who was willing to risk everything for a chance at a new life. They point to the fact that he left behind his fingerprints on the plane, which suggests that he didn't think he would be caught.
Still others believe that Cooper was never real at all. They point to the fact that no one saw him board the plane or disembark after the jump.
The truth is, we don't know what happened to D.B. Cooper. And that is what makes his case so fascinating. It is a mystery that may never be solved.
