In the dimly lit room, the air stagnated for a moment.

Fucheng pursed his lips and looked away awkwardly.

The person being watched didn't respond, his eyes stopped for a few seconds on the young man's stiff side face, and a smirk flashed through Zhuo Huan's eyes. He leaned forward and said softly, "What did you see."

Fucheng: "..."

Zhuo Huan: "I'm at a disadvantage."

Fucheng still bowed his head without answering.

Zhuo Huan smiled and stopped molesting the man. He freed up his hands and cracked and typed on the keyboard. While typing, he said: "If you want to really rely on calculations to figure out the specific location of the Roger 318, the possibility is infinitely close to zero."

Fucheng turned his head: "Then you just said you want to figure out where Roger 318 is."

Really interested in this?

This sentence flashed in his mind, Zhuo Huan whispered "Yeah", without turning his head to look at the young man lying next to him, and continued typing: "Calculating where it is, it means calculating its approximate location. How big is the Pacific Ocean, do you know? Without letting Fucheng answer, he continued: "181.34 million square kilometers. Do you know what this concept is? The global land area is about 149 million square kilometers. Even excluding most of the Pacific Ocean... Well, one No matter how an airplane moves with ocean currents, it is impossible to float from Canada to Australia."

"Even in the waters near the west coast of Canada, the NTSB's aircraft salvage range is 5 million square kilometers."

"Half of China is as big as that."

Pressing the "Enter" key, Zhuo Huan turned around and looked at Fucheng: "Can you find an airplane in half of the map of China."

Fucheng: "...impossible."

"Yes, even you know it's impossible."

Fucheng frowned: Even you?

Zhuo Huan didn't seem to realize his own ridiculous words. He moved his neck and lazily said: "So, through calculations, reduce this range. When the range is reduced to only 10,000 square kilometers... it will definitely be found. ."

After a while.

Fucheng: "After announcing the stop of the investigation, have you been doing this alone, Teacher Zhuo."

Zhuo Huan: "Anyone? Of course not. I'm not a professional marine expert, ocean current sports expert, meteorological expert... I have a specialization in the surgical industry, and there are a few people who do this together." He raised his eyebrows, a little surprised: "I I was emailing Robert Gatsby just now. Didn’t you see? You don’t know him?"

Fucheng: "..."

"Should I know?"

His clear and narrow eyes slowly widened. After a while, Zhuo Huan: "Oh, he won the Nobel Prize in Physics in 2006. The supercomputer at the University of California, San Diego is in the hands of his laboratory. All our data After preliminary calculations, he enters it into the supercomputer for final calculations."

Fucheng: "...Hmm."

Zhuo Huan laughed.

Fucheng got up from the bed expressionlessly, picked up the pants that had fallen on the floor, and handed it to someone.

The man lying on the bed didn't mean to take it. Instead, he hooked his mouth: "You didn't wear underwear before you put on your pants?"

Fucheng: "..."

Another email came, and Zhuo Huan immediately looked at the computer. He commanded Fucheng without looking up: "Get a pair of clean underwear from my box. Where is the box... Hmm? Businesque's equation repeats..." He put down his laptop and looked for it in the quilt. I found the mobile phone I didn’t know where I threw it in, and I found out a number and called it out: "Robert, um, it’s me. If you re-derive it, the vortex viscosity parameter in the equation changes when the upwelling density changes and the temperature-heat difference is too large. ..."

Fucheng walked out of the room, went to the living room, and found the suitcase leaning against the corner. He took a pair of clean underwear from the inside. When he returned to the room, Zhuo Huan was naked, leaning against the head of the bed, with the quilt covering his waist casually, and one leg stretched out of the bed. Seeing Fucheng coming in, he stretched out his hand, took the underwear in his hand, then opened the quilt and put it on directly.

"The calculation is abnormal. Consider the problem of eddy viscosity parameters. My suggestion is..."

Putting on the trousers, he took a clean T-shirt from the sofa and put it on roughly.

When Zhuo Huan hung up, it was already five minutes later.

Fucheng looked up at him: "I have told Lina to let them go first. Let's take a taxi later."

Zhuo Huan was taken aback, he tilted his head and looked at the young man in front of him. "Are you trying to do something with me?"

Fucheng didn't reply to him, but said, "Professor Robert Gatsby, I just checked his information on Google. He is a very powerful physicist."

Zhuo Huan chuckled, "Am I not good?"

After a moment of silence, Fucheng looked at Zhuo Huan: "Teacher Zhuo, can you find it."

The youth's clean and beautiful pupils reflected clear and bright colors. It was quiet and peaceful, but silent, and looked at Zhuo Huan without blinking. Obviously there are many answers, you can find one at random to answer this question. But Zhuo Huan's heart moved slightly, and the youth's expression was calm and composed, but he saw the stubbornness and determination like a stubborn bamboo.

For a long time, Zhuo Huan: "When you look for a lost thing, do you think about finding it all at once?"

Fucheng: "No."

Zhuo Huan stepped barefoot on the carpet and walked to Fucheng's side. He leaned slightly, Fucheng held his breath.

Over the youth, he took away a watch that was on the chair behind Fucheng. It was the piece given to him by the three of Fucheng on his birthday last week.

Standing up straight, after tying the watch, Zhuo Huan stretched out his hand, he lifted Fucheng's chin with his fingers, forcing him to look at himself.

The man's voice was soft and mellow, and he spoke ambiguously and mutely.

"It's like I did a lot of things before I got up to you. These things seem meaningless, none of them can make me get up to you right away... But the result is inevitable. I will get up to you, I Roger 318 will also be found."

With eyes facing each other, Zhuo Huan quietly examined the young man looking up at him, but he could not see any emotions in his calm eyes.

He laughed, let go of his hand holding Fu Cheng's chin, put on his shoes and walked to the bathroom.

Zhuo Huan: "Let the front desk find a car first. I'll be fine soon."

Fucheng: "Yeah."

The moment the door to the bathroom was closed, the young man's original calm expression suddenly cracked. The hand holding the phone trembled slightly, and the roots of the ears were inevitably red. His chest was up and down, but he still tried to maintain a calm look on his face. He panted slightly, and then buried his face in his palm.

Ten minutes later, the two went out together.

When arriving at the investigation headquarters, Lina was watering the flowers.

Zhuo Huan: "When did you buy the flowers?"

Lina smiled softly: "I bought it the first day I came. Reid, it’s the fun of life. In the past, you didn’t have a pair of eyes that found beauty, so you couldn’t see it. I’m very happy that you have such a pair of eyes today. It’s a pity you You can find beauty, but correspondingly, you lose your aesthetics." She pointed to the watch on Zhuo Huan's wrist, "Patek Philippe is not worthy of a T-shirt at all, especially this one on you."

Zhuo Huan didn't care, and took a cup of coffee in hand: "I don't wear it to show you, but to show others."

Lina raised her slender eyebrows. She saw Fucheng also enter the door. She said to Fucheng, "Fuck, Reid said it wasn't for me, but was it for you?"

Fucheng turned his head to look at Zhuo Huan: "Teacher Zhuo, is this a cold joke?"

Zhuo Huan: "You said that it is."

Fucheng: "Oh, that's not funny."

Zhuo Huan glanced at him and said to Lina: "After an hour, inform them of the meeting and officially start the investigation."

Lina: "Okay."

An hour later, GCAA investigated the headquarters and conference room.

Old Joseph stood in front of the large white board and explained the specific details of the 411 air crash to all investigators present. Since everyone has read all the 96 boxes of survey materials, Joseph Sr. spoke very relaxedly, and no one raised any doubts.

After speaking, Lina said: “GCAA contacted NTSB yesterday at noon and told them the situation. As far as I know, NTSB sent someone over this morning and should arrive in Dubai tomorrow. Reid, they brought the information. Coming."

Zhuo Huan: "OK, how is the wreckage of the plane." He looked at Fucheng.

Fucheng and Maiha looked at each other, and the latter brought a large cardboard box from under the table.

Fucheng Road: "The Emirates Airline 411 crash was an accident 23 years ago. The wreckage of its aircraft was almost shattered due to a violent explosion. Therefore, GCAA did not keep the wreckage of the aircraft intact, only the engine. Part of it is what you can see now. This is the only thing left from the engine on the right side. After the explosion...it only has so much left."

Inside the box is a transparent rectangular glass frame, inside which is placed a black metal object measuring 50 cm in length and width and 30 cm in height. It was scorched all over, and it burst out of shape. Even Zhuo Huan looked at it for a minute, but couldn't recognize which part of the engine it belonged to.

Maiha said: "Arab Airlines is the best airline in our country. The 411 air crash is the most tragic and serious accident since their establishment. Emirates has assured me that they will fully support the reinvestigation of the accident. They also want to do so. Know the truth." After a pause, he added, "This full support includes financial support."

Zhuo Huan raised an eyebrow: "Including a Boeing 777 for research?"

Maiha was stunned: "This, this...I'm not sure about this. But I can contact the person in charge over there and ask him if it's okay."

Zhuo Huan: "Then you can contact me now."

Maiha: "Huh?" He thought Zhuo Huan was joking.

Zhuo Huan: "Does the full support not include giving a Boeing 777?"

Only then did Maiha know that Uncle Zhuo was serious about asking for a Boeing 777 from Emirates. He had a complicated expression, nodded, and stood up: "I'm going to call over there."

Everyone present: "..."

As if he didn’t think there was anything wrong with asking for an airplane worth more than 100 million yuan in one mouth, Zhuo Huan stood up, walked to the whiteboard, and wrote a word——

"Shards".

"The NTSB people haven't arrived yet, and the Boeing 777 provided by Emirates hasn't come..."

Everyone: "..."

Are you so sure that Emirates will give you a Boeing 777 for casual research!

Who gives you the confidence!

Zhuo Huan continued: "First of all, we must determine the order of time. It is this piece of slap-sized fragment on the right flap that flew out of the fuselage first; then, the fan blade suddenly broke in the low pressure cavity of the right engine. . Or at least, these two things can happen at the same time, but it is absolutely impossible. The latter happened first."

"Then the problem is..."

"Under what circumstances, a Boeing 777 that has only been put into use for one year, there will be damage to the metal material on the upper surface of the aircraft's flaps."

"This is the answer you need to find out."

"Okay, the meeting is over."

Zhuo Huan announced the mission, and everyone in the investigation headquarters began to study this issue.

Su Fei thought about it for a long time, and suddenly said: "I thought about it."

Everyone in UAAG looked at him together.

The punk boy is no longer as rebellious and individual as when he first met. He took off the three studs from his ears, leaving only a black skull. At this moment, he touched the black skull on the earlobe, coughed, and said: "Previously declare that I am still young, I am a minor, and I am inexperienced! I just made a guess, don't laugh if I am wrong!"

Everyone: "Don't laugh at you."

Su Fei was energetic and excited: "The simplest answer to this question is that the repair is wrong!"

Fucheng frowned slightly.

Su Fei said: "Last year's Masa Airlines 123 crash, was it because the aircraft was repaired and the screwdriver of the wrong size was used, which eventually caused the aircraft to fly in mid-air and the tail suddenly dropped? Sorry, Lina, I didn't mean to mention it. This incident makes you sad, I will give you an example."

Lina shook her head: "It's okay."

Old Joseph smiled slightly and touched his chin: "The answer you said is actually the most likely."

Su Fei's eyes lit up: "Really!"

Old Joseph: "In 1989, United Airlines 232 air crash, a DC-10 plane from Denver to Chicago crashed in Sioux City. The cause of the accident was that the engine fan blades suddenly broke, cutting the aircraft tail and all the hydraulic systems on the plane. …Oh, the break of the fan blade is not a repair error, but a defect at the beginning of the manufacturing. But you said that the repair error caused the metal material on the surface of the aircraft to peel off, which is very likely."

Su Fei was encouraged, and nodded: "I think it makes more sense to hear what you said. You see, the chronological order of things is like this. First, the metal surface of the flap peeled off, and then it didn't fly away. Well, actually! It didn't really fly away, it flew under the plane and got caught in the engine!"

Old Joseph applauded: "Then is this piece of debris that split the blades of the airplane's low-pressure fan, and finally caused an air crash?"

Su Fei: "Yes!"

Fucheng said helplessly: "Don't tease him, old Joseph."

Old Joseph laughed loudly.

Su Fei: "......???"

Su Fei is a computer major, and no one knows why he is a Turing Award nominee involved in the investigation of aircraft accidents, and he has such a deep research on black boxes. But there is no doubt that he doesn't know much about the aircraft itself, and most of his knowledge has been learned and sold in the past six months.

Fucheng explained: "The Sucheng air crash was caused by broken fan blades and cut off the tail. But your guess is not good. The low-pressure fan can fly out of the engine, but nothing can fly into the engine and cut its low-pressure fan. Because it is passing by the engine. It must have been burned to ashes when the fuel cavity of the engine was burned." The voice stopped, Fucheng concluded: "In short, the fragments peeling off the flaps are absolutely impossible to cause the engine fan blades to break."

Su Fei: "..."

The punk boy turned his head and glared at old Joseph: "You laugh at me on purpose!"

The old Joseph was extremely innocent.

Fucheng: "In fact, Su Fei's guess is indeed the most probable cause."

Everyone looked at him together.

Fucheng pondered for a while, and said: "The most likely reason for the peeling of the outer surface of an aircraft is of course the quality of the aircraft itself. For example, manufacturing defects such as the Sioux City air crash, or the Marks and Spencer Airlines flight 123, used the wrong way for maintenance. Screw. The former is a manufacturing problem of Boeing, and the latter is a maintenance problem of Arab Airlines. Well, it is definitely not a maintenance problem of Arab Airlines, it may only be a manufacturing problem of Boeing."

Su Fei was surprised: "Why is it not the maintenance problem of Emirates?"

Before Fucheng spoke, Lina smiled first: "Su Fei, do you know the top ten safest airlines in the world?"

Su Fei shook his head.

Lina: "Emirates ranks in the top three. Aircraft accidents are inevitable. No one dares to say that accidents will not happen. It is absolutely impossible to eliminate air crashes. But reducing the probability of air crashes is not impossible. Money is good. thing."

Fucheng nodded: "All civil aviation pilots in the world know that the happiest pilot in the world is the Emirates pilot. Do you know what the average age of the aircraft is?"

A cold male voice sounded not far away from everyone: "How much?"

Unexpectedly, Zhuo Huan would also be interested in this, Fucheng was stunned, then turned to look at him: "55 months."

Zhuo Huan was stunned.

Old Joseph directly blew his whistle.

Su Fei: "Fuck, 55 months? 4 years and 7 months?!"

Fucheng nodded: "Well, it's 4 years and 7 months. First of all, it is absolutely impossible for Arab Airlines to have second-hand aircraft. They will not buy obsolete aircraft from any other airlines. All the aircraft they use are from Boeing. , Maifei, Airbus directly ordered. There are no small planes, all are big planes. Secondly, an average of only 4 years and 7 months between when an aircraft enters the Emirates apron and when it is sold by Emirates. Aircraft. Of course, the service life of the aircraft is more than 55 months. It can be used for ten, twenty, or even thirty years without any problem. But there is no doubt that the new aircraft will always be more trustworthy than the old aircraft’s safety index."

Su Fei: "I understand. So, they are willing to spend money to eliminate an aircraft every four years. Arab Airlines must be willing to spend a lot of money to repair the aircraft. It is absolutely impossible to be greedy for cheap... How much money will it cost? The evil capitalist!"

Fucheng: "Nor can you say that. If you are a complete capitalist, you will not be willing to spend so much money on buying and repairing airplanes. For example, American Airlines and JAL, if there is a maintenance problem with the airplane, there are two options-buy a new one. Parts, continue to repair. They will definitely choose the latter. Because the former costs millions or even tens of millions of dollars, the latter is a hundred times cheaper. But it’s different from Emirates. Similarly, when I was with Donghua Airlines, Donghua Airlines is also like this."

Old Joseph glanced at him and couldn't help but agree: "Although I used to be a pilot of American Airlines, I agree with you. Your Chinese airlines are really willing to repair planes, and they are generally very young. , It’s not much longer than the Emirates. It’s very famous in the industry."

Fucheng smiled and said: "Therefore, there are very few air crashes in China. Because in China, the lives are greater than the sky. I would rather spend tens of millions of dollars than an air crash. There are many reasons behind this, but in any case , Its ending is good, and China’s aircraft is very safe."

Returning to the subject, Old Joseph coughed and stopped teasing Su Fei. "If only the material on the outer surface of the flaps is peeling off, I believe it may be a Boeing manufacturing problem. If it is only a broken engine blade, I also believe it may be a Rolls-Royce manufacturing problem. But now the two are happening together..."

Everyone fell into contemplation again.

Fucheng turned his head quickly: "Teacher Zhuo, do you have any ideas?"

Zhuo Huan sat by the window, chewing gum, and stared at the three-dimensional structure of Boeing 777 on the computer screen. Suddenly by someone's name, he raised his head and looked at Fucheng.

The eyes of the two met in the air.

Zhuo Huan turned the pen in his finger and smiled casually: "The four of you, I am alone... Now, you ask me?"

Lina raised her hand and smiled and said, "I don't count, I don't understand anything, non-staff."

Su Fei quickly pulled the chair and sat back: "Don't count me, I'm a minor, I'm still a child!"

Zhuo Huan raised an eyebrow, but he still didn't answer directly. Instead, he asked Fucheng: "What do you think?"

Fucheng thought for a long time, and said seriously: "Two things, only one happened, and there are many reasons. But the two happened at the same time, I think...the cause of the flap surface breakage and the engine fan blade breakage, It must be the same one."

Old Joseph's eyes lit up: "The same thing split the outer surface of the plane and the engine? In 2000, the Air France 4590 crashed. A supersonic Concorde just took off and the left engine caught fire and finally crashed. After the investigation of the accident It was discovered that the previous plane dropped a long strip of metal part and left it on the runway. It severed Air France’s tires, and the tyre fragments cut the fuel tank and cables, which eventually led to a fire..." Just finished speaking, Lao Joseph himself was stunned for the first time. He shook his head: "No, Emirates 411 suddenly caught fire in the air, and it has nothing to do with the previous plane."

Fucheng: "In fact, before the 411 took off, the runway was inspected in detail, and there was no residual foreign matter."

Old Joseph smiled bitterly: "And I can't think of a foreign object that can pass through the fuel cavity of a Boeing 777 and cut its fan blades."

"Oh, then think about it."

Everyone turned around and looked at the man sitting by the window.

Zhuo Huan lowered his eyelids and scanned the three-dimensional structure of the Boeing 777 on the computer screen.

"Go contact Rolls Royce."

Obviously he didn't call his name, but Lina knew he was calling herself. She smiled and stood up: "Okay. What do you want me to contact them for?"

Zhuo Huan raised his head: "Let them provide a Trent 800 engine for experimentation."

Lina pretended to be surprised: "Just say, will they give it?"

As if he heard something funny, Zhuo Huan's lips curled up: "Twenty-three years ago, I suffered a big loss and was wronged by Boeing and NTSB for product quality problems... You said, will they give it now? "

Lina smiled and said, "Reid, you are really a bad guy."

Zhuo Huan: "Oh, I'm bad, there are still people who like it." As he said, he faintly swept towards Fucheng.

Fucheng leaned back in his chair and looked at him calmly.

The author has something to say:

Zhuo Anxi: In order to go to Fucheng, I also paid a lot, did a lot of things, and worked hard.

Fu Chengcheng: ......You are mad at me in this regard, you have been working hard.
