Looking from the tip to the root of the nearly seven-meter-long left wing wreckage, there were at first a half-meter long, messy white scratches, followed by a gap of about three meters. And on both sides of this huge gap, along the cracked metal section, like a spider web, black cracks spread out densely, like the wrinkles of cracks in the earth.

If an airplane crashes into the sea, it will inevitably cause breakage and damage to the fuselage.

At first glance, these injuries were very normal, but after Zhuo Huan's reminder, everyone discovered that it was wrong.

The old Joseph has many years of experience in air crash investigations. He tasted something wrong and touched his chin and said: "Reid, what do you mean, this crack is wrong? The plane crashing into the sea is a momentary thing, even if the plane barely keeps flying on the sea. In a few seconds, the moment it fell into the sea, it was destined to be destroyed by the powerful ocean power of the sea. This is a sea crash, not a forced landing on the river. It is impossible to have a Hudson miracle."

The sea is not a river.

In 2009, a US Airways flight 1549, shortly after taking off from LaGuardia Airport in New York, suffered a bird strike and all four engines failed. As a last resort, the plane had to make an emergency landing, and finally the captain chose to make an emergency landing on the Hudson River. The emergency landing was very successful. There were no victims and only a few people were injured.

This crash landing was called the Hudson's miracle.

But if this happened on the sea, the Hudson miracle would never happen.

During the movement of sea water, huge tidal energy, wave energy, ocean current energy, etc. are generated.

There is no difference between a plane landing on steady water and a landing on concrete. Not to mention landing on the rough ocean. The powerful ocean power will tear this aircraft apart, without exception.

Old Joseph: "As far as the fracture surface is concerned, I can't see what is wrong with the naked eye. It is the wing tip entering the water. The farther back, the larger the gap is, which is also in line with common sense. At the same time, there are two sides of the gap. Cracks will grow larger. These are all in line with the fracture toughness of metals. What do you think is wrong?"

However, Old Joseph did not expect that Zhuo Huan did not give an answer immediately after he asked this sentence.

Both Fucheng and Old Joseph looked at him, but Zhuo Huan frowned. He looked at the left-wing fracture for a long time, and finally raised his head: "I can't be sure, but this crack is full of my instinct. Some kind of strange feeling."

Fucheng: "What kind of strange feeling?"

"Should it be like this."

Fucheng looked at him: "Teacher Zhuo?"

Zhuo Huan: "Calculate first."

Investigation headquarters, conference room.

Su Fei: "Is it a human?"

Fucheng: "..."

The punk boy turned his head dissatisfiedly and said: "Brother Fu, you should now add a sentence of'don't look like'."

Fucheng: "..."

After a while, he was expressionless: "It doesn't look like it."

Su Fei nodded and sighed, "I'm afraid this is not a beast in human skin."

Zhuo Huan's tall figure paused slightly, and after a cold snort of contempt, he said without looking up, "Return the room for him and replace it with a standard room."

Obviously she didn't name her, but Lina knew that it must have been told to herself. She smiled slightly and said, "Okay." As she said, she picked up her mobile phone and was about to check out.

Su Fei rushed over in horror, holding the hand she wanted to call, turned her head and said angrily at Zhuo Huan: "Everyone lives in a suite, why should I live in a standard room! It's not you who pay, it's NTSB paying for it!"

After hearing this, Uncle Zhuo didn't lower his head to write the formula calculation. He raised his head and leaned back on the back of the chair, leaving Su Fei with an arrogant chin—not a double chin.

"Just because I am the person in charge of UAAG." Then looked at Lina, "Book him a small hotel on the street."

Su Fei: "It's not going to give people a way to survive!"

Zhuo Huan: "Shit."

The so-called low-mouthed, that's probably the case.

Su Fei burst into tears, regretting that he should not be cheesy in front of Uncle Zhuo. He kept acting like a baby at Lina, begging Lina not to leave his suite: "More than 10,000 a night! I haven't lived enough! I'm half tired every day, and when I go back, I point to lying in my comfortable jacuzzi. Here, you can live a life like this by having a SPA."

Lina smiled gently: "Why do you have to say in front of Reid, silly boy, you are behind him, you can do whatever you want."

Uncle Zhuo: "..."

"Humph."

In fact, Su Fei's mouthiness can't be completely blamed for this incident.

Fucheng quietly looked at a certain man and what was in front of him.

I saw a large conference table with countless A4 papers. A black ink pen is used on each piece of paper, and complicated formulas and calculation processes are written. It is not complicated to measure the fracture data and various physical properties of the left wing of the aircraft. But wanting to discover that little strangeness from it is as difficult as reaching the sky.

First, they didn't know what was wrong with the crack in the left wing of the plane. Then we must consider every aspect.

Could it be the inherent metal fatigue?

Before the plane fell into the water, the left wing broke, just because it fell into the sea and the original fracture was covered by a new one?

Could something have split the left wing of the plane?

For example, when Fucheng flew from New York to Boston half a year ago, the wing of the plane was split by engine debris.

There are many, many unpredictable possibilities.

So in order to find out that little strangeness, Zhuo Huan started a detailed calculation. Since the morning, he has been sitting at the table, and it has been calculated for four full hours. Various physical formulas and mathematical announcements slide out smoothly from the pen, without any sense of stagnation.

As if directing a grand and elegant symphony, every time he raised his hand, he stripped the symbols from the score, and put them on the paper in a cruel gesture that could not be rejected. In this way, it gathers into a majestic theoretical symphony.

No wonder this man can participate in the World Physics Congress.

This thought suddenly flashed in his mind. Before Fucheng recovered, he heard Zhuo Huan say: "Pour me a cup of coffee."

Suddenly sober, Fucheng glanced around. I don't know when, Lina has left the meeting room, Su Fei of course also followed her, begging her not to change the room for herself.

It seemed to be taken for granted that the black-haired young man stood up, walked to the pantry, poured a cup of coffee, and handed it to Zhuo Huan.

"Thank you." He lifted his head slightly, and stared at the hand holding the coffee cup. Realizing that this is not Lina, Zhuo Huan raised his head and looked at Fucheng. With his eyes facing each other for a long time, Zhuo Huan raised his eyebrows and said, "You won't go?"

Fucheng pulled a chair and sat down: "It just happens to read some materials. Will it bother you, Teacher Zhuo?"

He fixedly looked at the young man in front of him, his gaze stopped for a moment on those beautiful eyebrows.

Zhuo Huan smiled: "No."

Although he has always had no distractions when he works, he has never been disturbed by the outside world.

But it’s not a bad thing to have a good-looking person by your side, at least it can purify the air and be pleasing to the eyes.

This sitting took a whole day.

Fucheng rubbed his sore shoulder, raised his head, and found that Zhuo Huan was still calculating the fracture data of the left wing of the plane.

He casually took a piece of waste paper that was crumpled by Zhuo Huan and threw it into the paper basket, opened it and looked at it.

"...Griffith energy relationship?"

"you know?"

Fucheng looked up: "Well, I've seen it somewhere before. I should have seen it in theory class before."

Flying an airplane is not driving a car. Pilots not only have to learn how to fly an airplane, they also have to learn a variety of theoretical knowledge. From the most basic aerodynamics, electronic and electrical principles, to ergonomics, meteorology... everything.

Of course, it certainly does not include the fracture mechanics of metals.

Which pilot will have nothing to do and run to learn what to do if the plane is broken. In such a situation, it is more practical to learn how to skydive first.

Zhuo Huan lowered his head to calculate, while faintly said: "It was calculated on the assumption that the aircraft had metal fatigue, but the answer is wrong. Its left wing did not break in a static state, not brittle fracture, but plastic deformation."

Fucheng smiled slightly.

...Pretend to understand.

Fucheng: "Teacher Zhuo, do you have any clues?"

Zhuo Huan: "What do you think?"

Fucheng: "Do you want coffee?"

"Um."

I went to pour another cup of coffee, and when Fucheng returned to the meeting room, Zhuo Huan had already stood up. He was holding a piece of draft paper, standing under the bright incandescent lamp, raising his hands, looking at the contents of the paper through the light.

The bright light illuminates the white paper transparently. It passes through the thin paper and shines on the cold and handsome face of the man. Zhuo Huan narrowed his eyes slightly, his thin lips moved, and let out a deep sigh.

At this moment, he turned his head and saw Fucheng standing by the door.

Like the spring breeze blowing over the steep ice field, the confident and proud rays of light converged into the starlight in his eyes. He raised his chin towards Fucheng, waved the scratch paper in his hand, and the paper made a crisp sound in the air.

"Oh, I found it."

Fucheng looked at the man in front of him, his lips opened, but he didn't say a word.

After a while.

Fucheng: "Congratulations."

Hearing that the investigation had made new progress, Lowens immediately went upstairs to the conference room.

As soon as he entered the room, he looked at Zhuo Huan anxiously: "Patrick, did you find any new clues?"

Zhuo Huan raised his eyes and glanced at him: "Don't worry, sit down."

Lowens hurriedly pulled a chair.

Lina has input all the data calculated by Zhuo Huan into the computer and projected it on the screen.

Zhuo Huan stood up and started to explain what was on the screen.

"According to the deformation and compression rate of the metal, when the American Airlines 4012 enters the water, the surface tension of the ocean is destroyed, and a reverse force is applied to the body of the fuselage..." The voice stopped abruptly, looking at Su Fei and others. Unknown expression and Lina's polite smile, Uncle Zhuo suddenly felt the cold from the heights, sighed in his heart, skipped the process, and said: "All in all, for preliminary calculations, except for the acceleration of gravity and the airspeed of the aircraft itself, it is beautiful. When Hang 4012 crashed, the aircraft was accelerating and rushed into the sea. Moreover, the acceleration reached at least 7m/s."

As soon as this sentence came out, there was a sudden silence in the conference room.

Old Joseph opened his mouth and said, "You mean, this plane...is actively accelerating into the sea?"

Uncle Zhuo raised his eyebrows: "I think I made it very clear."

The crowd was in an uproar.

Su Fei also felt incredible: "I speeded up into the sea, meaning that the pilot kidnapped the plane and committed suicide?!"

Zhuo Huan cast his gaze and was about to speak. Fucheng's voice rang in front of him: "Teacher Zhuo didn't mean that, but it's a possibility. What is currently known is that when the plane rushed into the sea...The state of almost maximum acceleration."

The author has something to say:

Zhuo Anxi: Fucheng stayed beside me, purifying the air.so, Fucheng = air purifier.

Fu Chengcheng: Huh.
