Southwest Airlines check-in counter at Dallas, Texas, November 24, 1971.

A tall, middle-aged white man with brown hair and a cyan suit walked up to the counter and smiled at the conductor: "Hello, I'm Dan Cooper, give me a one-way ticket for Flight 305, I'm going to Los Angeles to see my girlfriend." ”

The conductor took one look at him, noticed that he was dragging a large suitcase, then took the cash and gave him a ticket.

Getting his ticket, Dan Cooper looked at the time, dragged his suitcase to airport security, and boarded the plane with boarding instructions.

The plane did not take off in time because a shipment of gold weighing 120 kilograms was being transported from the Bank of Dallas to be sent to the Los Angeles area to stabilize the foreign trade market in Los Angeles.

The convoy carrying the gold was late, and they encountered a traffic accident on the way, and the convoy changed routes, fearing that it was a deliberate accident caused by someone robbing the gold.

As it turned out, the convoy was right in its fears, and on either side of the crash was a group of cowboys from South Dallas, with guns in their arms, and they had bad intentions toward the gold.

The flight attendant apologized again and again, and many passengers were very dissatisfied, so the crew decided to give everyone some drinks and food to calm the passengers' anger.

Dan Cooper, by contrast, was very calm, and the stewardess came over with a cart, ordered a bourbon with soda, and tipped the stewardess twenty dollars.

In those days, a twenty-dollar tip was a lot, and the flight attendant was delighted and smiled at him.

At three o'clock in the afternoon, the plane was in the air, and Cooper took out his suitcase and began assembling something.

You must know that the American aviation industry is very developed, and many flights are not crowded, and Dan Cooper's location is a hidden corner, and there are no passengers around, so no one can find out what he is doing in time.

Cooper sipped whiskey and assembled something, then he beckoned to the flight attendant.

Because of the previous tip, the flight attendant had a good impression of this generous middle-aged handsome guy, so she smiled and asked, "Sir, is there anything you need help with?" ”

Cooper also showed a pleasant smile: "Yes, ma'am, can you please give me a sticky note?" ”

The stewardess quickly tore off a sticky note and handed it to him, he wrote it on the paper, and the stewardess had some small expectations in her heart, because she felt that she was beautiful and sexy, and passengers often wrote confessions to her.

She was thinking, if this handsome older guy with a generous hand also wrote a confession to himself, should she accept it?

The stewardess was thinking about it, and Cooper finished writing and handed her the note.

Stretching out her slender hand, the stewardess took the note and looked down, and the sweet smile on her face froze: I have a bomb here.

Looking at the contents of this note, the flight attendant was frightened: "Sir, please don't joke......"

Cooper smiled and drank the whiskey in his glass, opened the clothes of the next seat, and a bomb tied together appeared in front of the flight attendant, with intricate wires on it.

The stewardess was about to scream in fright, but Cooper quickly stood up and put his finger on her lips to block her screams, and chuckled: "Go, tell the captain everything here, tell him that I want something from him." ”

With the note, the flight attendant left in a hurry.

Soon, the captain arrived, and he asked calmly and vigilantly: "Sir, what do you need, you can tell me, don't get excited, I will help you get everything done......"

"I'm not excited, I want the two boxes stored in your cab to be brought to me, and prepare four parachutes, don't do anything on them, or we'll all fall into the Rio Grande." Cooper smiled.

The captain's scalp was numb, and he wanted to argue, but Cooper didn't give him a chance, so he directly took out the bomb and said, "Don't waste time, I'm timed on this." ”

Eventually, two large heavy boxes appeared beside Cooper, who checked the contents and nodded, "Contact an airport and we can land." ”

The plane landed at Sufford Airport, the passengers on the plane were quickly evacuated, and the crew members were forced to stay.

A few hours later, at Cooper's request, the plane quickly re-took off and continued in the direction of Los Angeles, but not more than 10,000 feet.

Just after 8 p.m., Cooper closed the crew into the cockpit.

Then, at some point, he opened his parachute with two boxes of gold ingots and jumped off the plane and disappeared into the night.

This is the DB-Cooper plane robbery that shocked the United States for decades, because of the 120 kilograms of gold and the significant impact, the FBI quickly intervened in the case and launched an investigation.

The case was so influential that ten years later, in 1981, Hollywood brought it to the screen and filmed the movie "Eagle Hunting" about the plane robbery.

In the previous decade, a steady stream of books on the case had appeared on the market, such as "The End of the Rainbow", "Aquila", and so on.

Legend has it that Cooper landed in the town of Ariel, Arizona, so every year, Cooper fans gather in front of Ariel's grocery store tavern for a party.

For them, Cooper, who challenged the authority of the government and won, was a hero, and for this was born a festival, the DB-Cooper Festival, which is held every year on November 26.

A few years ago, the F.B.I. announced a moratorium on its active investigation into the hijacking case, but people interested in D.B. Cooper have been rushing to the scene, and all sorts of clues and evidence are confusing, both true and false.

To this day, private investigators continue to say that they have found some clues about Cooper.

Because there had been no major gold transactions on the market for several years, the FBI and the police believed that the gold had not been disposed of.

The 120 kilograms of gold became a treasure trove for many would-be Americans, and the value of the gold added to the mystery and appeal of the case.

Li Du listened to the introduction of the treasure pickers, which made him dumbfounded.

These guys are really living treasures, in Li Du's eyes, they are definitely drama spirits, one by one, they keep adding drama to themselves, as if they were acting in a stage play, showing this case in front of Li Du.

He thought it was ridiculous, because he knew it wasn't true.

Li Du asked: "Then did the FBI think about how Cooper escaped the security check with explosives and boarded the plane?" Also, didn't they suspect the crew members? All of this is the words of the crew members. ”

"Yes," Hans said, "the crew members were investigated, and they were in a lot of trouble at the time. However, there was no evidence of their involvement, and the FBI has since monitored the bank accounts of the crew members at the time and has never found any problems with their accounts. ”
