"Xiao, I regret it!" Eminem looked sad.

After all the people left, Xiao Peng and they returned to the life of scientific examination again, as if nothing had happened --- the most annoying thing to be famous.

But Eminem has been speechless to the extreme. Why? It's just that the boat is so boring! Just a little space, then a few people, no matter who stayed at sea for half a month, would be crazy.

Xiao Peng, who was not slow, sat on the side of the boat. Look at Kim. They're smart. They're going. Look at you, you fool, and you must stay. I advised you at that time that you would not listen. "

"It's been a lot of work, and this year's Grammy has been very angry. So I want to find a place to relax. Who would have thought it would be like this. " Am said with a bitter face.

Xiao Peng asked curiously, "isn't this relaxing? What does relaxation look like in your eyes? "

Eminem didn't even want to think about it and replied, "beautiful wine."

Xiao Peng curled his mouth: "vulgar, so you can speak with the fierce son, you two a virtue!"

Yang Meng's ears are sharp: "Hey, it's not good people who speak ill of others behind their backs."

Xiao Peng pointed to himself: "do you think I look like a good man?"

"No!" Yang Meng did not want to answer directly.

"What else do you ask?" Xiao Peng asked.

Yang suddenly sighed: "people do not want to face, the world is invincible."

Xiao Peng smiles and changes the topic: "how are the warriors of the four seas?"

Yang Meng shook his head after listening to it: "it's still there to try. Huang Bin says it's luck. Maybe it will be sent back! "

After hearing this, Xiao Peng angrily scolded: "special, we must change the ship! This is not a boat for scientific research! Tell Huang Bin, do your best, anyway, you have found the baby this time! I can't go back home! If you want to do a good job, you must first sharpen your tools. We can't carry out a long-term scientific research project on this ship! I want to go back and transform this ship into a yacht, and then order a comprehensive scientific research ship. What do you think of it? "

The four seas warrior broke down again. This time, there was a problem with power transmission. Huang Bin is a good mechanic, but the "Four Seas warrior" is beyond his ability, so now I feel helpless. Professional personnel are needed to solve the problem, but it seems that the ship is too small.

However, there is no problem for them to go back now, because this time they have really gained something!

In addition to polymetallic nodules, they found a large vein of rutile and monazite in the coastal sands!

Rutile, needless to say, is high-purity titanium dioxide. The content of titanium dioxide in a piece of rutile is more than 95%. The metal titanium extracted from this thing is resistant to high temperature, low temperature and corrosion. However, it is in short supply in China, with an annual output of only several thousand tons. It is one of the fourteen strategic reserves of China that relies heavily on foreign resources! And China's annual demand has reached one million tons!

Although the price of this device is similar to that of copper, it is in great demand, from welding electrodes to high-grade titanium white powder and rocket fuel! For this thing, it's worth mining here!

In addition to rutile, they also found monazite veins, which is more interesting.

In addition to niobium used to make rocket aircraft shells, monazite also contains tantalum for microcircuits, which is needed to make semiconductor chips. More importantly: there are uranium and thorium in it! It's radioactive! They usually find a lot of vein, but they don't need to protect it.

However, in any case, the discovery of these two veins and polymetallic nodule deposits this time is over fulfilled. So even if we return, no one says anything.

Xiao Peng stares for a long time, but he doesn't get the answer from Yang Meng. Looking back, Yang Meng looks up at the sky there.

"What are you looking at? Can't you hear me Xiao Peng asked.

Yang Meng exclaimed, "the people of xingtiao can play!"

"Well? Why do you say that? " Xiao Peng asked.

"It's the first time I've ever seen this jet playing stunt," Yang said

"Ah?" After hearing this, Xiao Peng was confused. Who played stunt on a domestic jet?

He followed Yang Meng's sight and saw that there was an airliner flying in the sky.

It's not surprising to see a plane over the Aleutian Islands.

Many people think that the plane from China to xingtiao is flying directly over the Pacific Ocean. In fact, this is not the case,.

Take Dido to Los Angeles. After taking off, the Chinese plane will first go north, cross Mongolia, bear country, Bering Strait to Alaska, fly into maple leaf country, and then to Los Angeles.

This is because the plane will have many accidents in flight. If it falls into the sea, it is difficult to rescue. Therefore, when flying, it always flies along the land. Even if it is over the sea, it will not be too far away from the land.In addition, the air flow in the Pacific Ocean is very unstable, and there are often bad weather. As a fisherman, Xiao Peng deeply understands this. Flying in such a place is very dangerous.

Xiao Peng looks at the airliner in the sky, hey, he is really playing stunt flying as Yang Meng said.

Well, it's a bit of an exaggeration to call it aerobatics, but the plane's attitude is really weird - first the nose dive down for a while, then the plane pulls up for a while, then from the dive for a while, and then for a while......

Yang Meng was confused: "what is the pilot brother doing? Do you think there's too much oil on the plane? "

Xiao Peng can't understand it either. After watching for a long time, he can't think of a reason.

Hearing the excitement, Qian congcongcong ran out of the cabin to have a look: "I said, this plane won't fall down, will it?"

Xiao Peng gave him a look: "can you judge something good? The whole big crow's mouth

Qian congcongcong shrugged and said, "can I be blamed for this? I'll tell you, you know the Boeing 737max that fell off in the air force of Egypt, don't you? In fact, I almost took that plane at that time. I'm afraid to think about it now. "

Some time ago, a Boeing 737max crashed in siabeba. No one survived. It was a brand-new aircraft only four months ago. There is also a Chinese girl on the plane.

After the incident, people think of a two-month Boeing 737max crash in Indonesia last year, only to find that this is a very terrible aircraft with fatal safety defects, so countries around the world began to stop flying this type of aircraft.

This is a tragedy in itself, but it caused a stir on the Internet in China. The reason is that the girl has a lot of money in her family.

As a result, there are all kinds of sour words, such as "a thousand miles to send X life back" and so on.

Is this what people say? Is Dutchman from the orphanage? No parental education?

In the eyes of these dirty people, as long as they are richer than me, they will die! Red eye disease to the people on this really can't say anything. Besides, let's not say whether they have foreign boyfriends. If they do, it's none of your business?

In the eyes of some people (let's call them people for the time being), it's funny that Chinese men seek foreign women to win honor for their country, while Chinese women look for foreign men for money and Diao. Isn't that funny?

Yang Meng said with a smile: "it's impossible. Boeing 737max is grounded all over the world. How can you still see that thing now?"

Xiao Peng was stunned. He thought about it carefully and looked up at the sky: "fuck! You're really right. This is a Boeing 737max. What's star country? Boeing's hometown! All the other countries in the world have grounded this plane, except for StarCraft! People say their plane is safe! "

"How do you know this is Boeing 737max?" Yang Meng asked

"Don't you see the two big engines? It's out of proportion! " Xiao Peng took a cool breath: "Mengzi, you go to get the telescope, I rely on it. How can I look more and more like something is wrong? Is MCAs sick again? "

The Boeing 737 has been on sale for more than 50 years since it was launched. It is one of the most successful narrow body civil aircraft in the history of civil aviation in the world. Up to now, it has developed 14 models.

And the problem is this fourteenth model - Boeing 737max8.

Compared with the previous model, the biggest feature of Boeing 737max8 is the replacement of two leap-1b engines. This engine saves 15% fuel and has more powerful horsepower than its predecessor! Make max8 the farthest plane in Boeing 737 series.

However, because of the replacement of the engine, it is easy to make the wing produce a higher angle of attack. To put it simply, the plane will look up when it flies. If you look up too much, the aircraft will lose its speed, which is what we call stall.

In other words, the higher the aircraft head is, the more likely it is to lose lift and fall off!

Boeing's designers did not take this into account, so they designed a mobile feature enhancement system, which is commonly known as MCAS. This system looks very high-end. In other words, it is similar to the autopilot system on cars. If the vehicle is deviated from the lane during the driving process, the autopilot system will correct the front end, while the MCAS system will be correct. When the aircraft head is too high, the aircraft nose is forced down!

but after all, this is an automatic control system, just like the automatic driving system of an automobile. If the sensor works normally, then the automatic driving is normal, but what if the sensor is apart from the fault?

The same is true for the MCAs system, which has an angle of attack detector. If the detector fails, the MCAs system will push down the nose of a normal flying aircraft and eventually cause an air crash.

After the Boeing 737max crashed in Indonesia, it was for this reason that the black box investigation was carried out. The air crash of air Egypt should be similar.

So the plane is now grounded around the world, and only StarCraft can see it.Yang Meng looked up and suddenly turned over and slapped Qian congcongcong on the head.

"Pain, Mengzi, why do you hit me?"

Yang Meng pointed to the sky: "you crow mouth, let you say it! There's something wrong with the plane! "
