A man took a plane in 1971. 


On November 24, 1971, a man hijacked a plane. 

The plane landed in Seattle. Cooper let the passengers go. He told the crew to refuel the plane. Then, he ordered the plane to fly again. After takeoff, Cooper opened the back door. He jumped out of the plane into the dark woods. 
No one knows who he was. In 1980, some of the money was found by a river. The FBI studied the case for many years. They stopped their main study in 2016. Many people still try to solve the mystery today. 
The story of D.B. Cooper is one of the most famous mysteries in history. 

Cooper’s plan was very specific and bold.

The story of D.B. Cooper is a unique mystery in aviation history. 

Cooper's method involved a very specific set of demands. Shortly after takeoff, he handed a note to flight attendant Florence Schaffner. He whispered that he had a bomb in his briefcase. 

During the flight, Cooper's behavior was noted by the crew. Flight attendant Tina Mucklow acted as a liaison. She described him as not being nervous or cruel. He even offered her a cigarette. However, he became upset when asked about his identity. 

Investigators have searched for clues for many decades. In 1980, a small portion of the money was discovered. 
There are many notable details regarding the hijacker's identity. Witnesses described him as a white male in his mid-forties. He had dark hair and brown eyes. He wore a black or brown business suit and a black raincoat. Interestingly, the name "D.B. Cooper" came from a reporter's error. His true name remains unknown to this day. Some people have been investigated as potential matches. For example, investigators looked at individuals like Richard McCoy, Jr. 

The hijacking had a massive impact on the aviation industry. It prompted immediate and major upgrades to airport security. Before this event, security measures were much less strict. Following the crime, airports began installing metal detectors. Baggage inspection became a mandatory process for all travelers. Authorities also began to scrutinize passengers who paid for tickets with cash on the day of departure. These changes were designed to prevent similar acts of air piracy. The legacy of the hijacking lives on through these safety systems and the enduring mystery of the man in the black raincoat.
