Generally speaking, jet airliners cannot maintain flight at such low speeds.

But Cooper told the crew that he knew very well that the lightweight Boeing 727 airliner could do this;

He also warned pilots not to try to play tricks. He wore a portable altimeter on his wrist that could easily tell if the plane was flying below 10,000 feet.

In addition, Cooper seems to be very familiar with the speed of refueling of passenger planes.

When refueling took more than 15 minutes, he warned that it must be filled up immediately, otherwise the bomb would be detonated.

After the refueling was completed, Cooper negotiated the flight route with the crew and emphasized that there was no need to pressurize the cabin for oxygen.

At 19:46, flight NW305 took to the sky again.

Shortly after the plane took off, he began to equip the parachute. According to Cooper's request, all four crew members entered the cockpit, and the plane also maintained a high altitude and speed.

Just after 20:00, the warning light on the dashboard came on, indicating that the boarding door at the rear of the aircraft was opened.

In other words, someone opened the door of the airplane cabin.

The deafening sound of the engine filled in. It was dark outside and there was a strong wind.

Below is the most rugged terrain in the country: a variety of pine and spruce trees, and even a grand canyon infested by mountain lions and bears.

The captain asked over the cabin phone: How can I help?

Cooper responded simply and simply: "No! These were his last words.

At 20:46, the pilot noticed that the tail of the plane trembled slightly, and then returned to normal.

He marked this location - the Lewis River Basin 25 miles (about 40 kilometers) west of Portland.

At 22:15, the plane landed safely at Reno Airport according to the agreed route.

The anxious crew member walked out of the cockpit after waiting for a few minutes, finally convinced that the nightmare was over: the cabin was empty, and Cooper had already opened the door during the flight and parachuted away.

Federal agents immediately conducted a large-scale search of the area, but found nothing.

The police also announced part of the banknote numbers for the $200,000 ransom, and offered a reward of US$1,000 to the first person to find a banknote. However, these banknotes, which are very common on the market, have disappeared like mud in the sea.

Someone even set up a website for people to check whether the number on their $20 bill is one of them.

Subsequently, the police launched a dragnet search, but found nothing and Cooper left no trace.

When the task force raised 10,000 US dollars, they urgently registered the serial numbers of these banknotes.

However, nine years later, in 1980, an 8-year-old boy accidentally dug up 290 photos in the woods along the Columbia River, and some of them were burned.

After expert appraisal, it was confirmed that the money was part of the ransom, amounting to approximately US$6,000.

Maybe, on that dark and cold night, someone used them to light a bunch of expensive bonfires.

Although the damage was serious, the number was still legible. This was the only appearance of the ransom. The numbers of the other 9,710 banknotes have never been discovered by the public security agencies.

People think this Cooper is as magical as Robin Hood.

Some say he may be living on some beautiful tropical island with money;

Some say he may have lived near Rivera;

Some people also believe that he died during that parachute jump.

However, Cooper's body was never found, and his parachute also disappeared without a trace.

An extensive search by federal and state police turned up nothing.

In DC, the task force discovered that Cooper's name was simply a pseudonym.

But Dan Cooper has begun to spread in this country as D.B. Cooper.

A reporter got the wrong name from a police informant and published it as D.B. Cooper.

Regardless of whether it is correct or not, it sounds very pleasant and full of mystery.

D.B. Cooper gradually became the idol of ugly people.

This is the true story of the legend in the original history.

But in movies and TV shows, DB Cooper is almost magically transformed. Just like in this world right now, the money in DB Cooper’s hand is not 200,000, but 5 million!

A total of 5 million non-consecutive banknotes is a huge amount of money at any time.

As for the whereabouts of this huge sum of money, only two people in the world know, one is Maikou and the other is Gao Bin!

No, I'm afraid only Gao Bin knows the most accurate location, and Maikou only knows a rough idea.

"Man, what are you going to do?" Sucre asked.

"Go back to Ugly Country, go to Utah, and come back as soon as you get the money."

Throughout the Americas, knife music is used as hard currency, so you don’t have to worry about having nowhere to spend the money when you get it back.

Maikou asked:

"Do you have a plan?"

"We've always had a plan, but we can't all go, one of us has to be left to look after the house."

Maikou breathed out:

"Obviously this person is me."

He stayed behind to look after the house, and no one had any objections.

"Well, the main thing is that you can't get involved in our affairs. If something unexpected happens and a few of us are caught, you can still find a way to rescue us if you stay outside."

Maikou nodded:

"I have no objection, just tell me your plan."

...

A week later, Gao Bin took Lincoln and Sucre back to the United States via a secret route, rented a black car at a high price, entered Utah, and went straight to the town where the farm was located.

Lincoln was in charge of driving, while Gao Bin followed his memory and scanned the streets with his eyes.

"Man, where did you get this address?"

"It's been analyzed, Sucre, stop talking nonsense, look for a map and see where Snow Pu Road is."

Sucre took out a paper map and searched inch by inch:

"Found it, Shep Road, 5 kilometers away from our current location, Lincoln, heading east."

"Received."

Utah has a vast territory and is sparsely populated, so there is no problem of traffic jams at all. You can get there in just 5 kilometers on gas.

Driving along Xuepu Road and reaching the intersection, Gao Bin noticed the road sign. This was the intersection of Xuepu Road and Kekesin Road:

"This is it."

After getting off the car and looking around, there was only one house surrounded by big trees in the vast emptiness.

Lincoln and Sucre got out of the car and followed his line of sight:

"That's it?"

"Yes, that's it, we have to make some preparations."

He remembered that the owner of that house was a very coquettish middle-aged woman, and her daughter was very beautiful, but she was a policewoman.

"Let's go, make some preparations, and try to get the money before dark."

The three of them divided their work. Lincoln went to destroy the house's electricity, while Gao Bin and Sucre went to the electric power company.

...

An hour later, Gao Bin drove back in a power company van. He and Sucre had already changed into power company clothes.

Of course, I also made a set for Lincoln, but it looked a little too small when I wore it.

"Let's go."

Gao Bin took the lead and knocked on the door.

After waiting outside for a long time, the door opened, and there was an old woman with big red lips at home.

"Who are you?"

"Madam, good day, we are from the electric power company. The detection system has alarmed. There seems to be a problem with your power supply?"

The woman looked at Gao Bin and the other three. They had simply put on makeup, so at least they wouldn't look like fugitives at first glance.

Their photos are all over the country, and Gao Bin cannot guarantee that the other party has not seen him and others.

"Yes, I didn't expect your service to be so attentive. Come in."

Gao Bin smiled:

"Yes, madam, take us to the basement. The problem should be caused by the aging of the cables buried underground."

"So we still need to dig the ground?"

"Yes, we will work as soon as possible and try to finish it before dark, so we can restore it to its original state."
