Ten days later, Toulouse, France.

This ancient city in southwestern France is a well-deserved aviation center in Europe. Rose-red bricks and tiles dot the streets and alleys of the city, and the South Canal winds through the center of the city, giving rise to thin waves like diamonds.

Toulouse is the headquarters of Airbus, one of the world's three well-known aircraft manufacturers. In addition, the headquarters of ATR is also located here.

After arriving in Toulouse's Space City by car, Fucheng did not go to the city's most famous Airbus headquarters, but went to ATR.

ATR72 is the plane piloted by Martha 123 this time.

Last week, investigators from Fucheng and EASA carefully investigated the weather conditions on the day of the accident and consulted with meteorological experts. The final conclusion is that the thunderclouds 20 kilometers away will never form an undershooting pressure, which will affect the flight of Martha 123.

In addition, as the air traffic controller said, other planes flying from Zurich to Berlin that day also said that the weather was good and there were no strong air currents.

So today, Fucheng and the old Joseph came to the ATR headquarters.

Under the leadership of the technicians, they came to the simulator workshop of the ATR headquarters. This is a huge warehouse with everything from ATR’s most classic ATR42 aircraft to the subsequent ATR72 and 82. It's not that there are many airplane models displayed here, but many flight simulators are installed.

Flight simulators are equipment used by pilots to simulate flight on the ground.

The entire simulator only retains the cockpit part. After the pilot sits in the driving position, he uses the ultra-wide-angle and long-range large screen to simulate real flight. Through the simulator, you can personally feel the turbulence of the aircraft when it encounters airflow, the vibration of the engine, and even the overweight feeling during inertial take-off. Everything is no different from real flight.

Fucheng took the form handed over by the ATR technician, checked the contents of the task checked above, and handed it back to the other party. He said in English: "Okay, just follow the above."

"OK."

Fucheng boarded the plane with the old Joseph.

The two of them sat in the driver's seat and fastened their seat belts. The "aircraft" in the simulator were all parked in the channel building at the beginning, and the pilots needed to drive them to take off.

Just like sitting on a real airplane, Fucheng activates the airplane's power system in accordance with standard procedures. His voice was calm and methodically speaking about the contents of the flight list. On the other side, the old Joseph sitting in the passenger seat is the deputy captain today. He is responsible for confirming procedures and ground radio contact.

Fucheng: "... Flight Martha 123, please take off."

As if someone really responded, after waiting for a while, Fucheng raised his eyes to look at the old Joseph. The two looked at each other and nodded lightly. The next second, Fucheng pressed one hand on the throttle stick and pulled it back. The roar of the engine vibrated in the small cockpit, and the surrounding buildings and vehicles flew back quickly in the large screen in front of them.

When reaching the decision speed, Fucheng held down the accelerator.

"Om—"

The nose of the aircraft rose suddenly, and the scene in front of him suddenly turned into a blue sky and white clouds.

Ten seconds later, Fu Chengcheng said: "The takeoff was successful."

In the co-pilot seat, the old Joseph smiled while reading the manual: "There is no turbulence, it is perfect. If every pilot can take off so smoothly, I think there will be at least half the number of airsick passengers in the cabin. After a pause, he looked at Fucheng, "Fu, what made you decide to conduct a simulated test drive? My view is the same as Reid, the pilot will not be the main reason this time."

Yes, it was Fucheng’s decision to come to the ATR headquarters in France and conduct a test flight this time.

After confirming that the weather was not the cause of the air crash, Fucheng thought for a long time and proposed to Zhuo Huan for a test flight.

At that time, Zhuo Huan was confirming the list of cargo on the plane with investigators.

After half a month’s careful inspection and the scorched goods were sent for testing, the investigation team determined that there were absolutely no flammable and explosive items in these goods, and no bombs were placed.

Holding a pen to sign on the cargo list, Zhuo Huan raised his head as he listened to Fucheng's words. He was a little tired, and his almost non-dormant work gave him a faint blue color. He frowned and looked at Fucheng. Zhuo Huan said, "Do you think... the pilot? Did you hear the cockpit voice record."

Fucheng naturally knew what he was going to say: "Listen. Obviously, the pilot did not show any abnormality before the aircraft system suddenly issued a warning. They did not misuse the flight to cause the flight to roll over."

"Oh? So?"

Looking at the man in front of him, Fucheng raised his head slightly: "I have never said that the pilot is the main cause, but Mr. Zhuo, the curve of the rolling posture is really strange. I want to know...under what circumstances, a civil aviation aircraft The plane can make that kind of magical roll posture."

Qingming's gaze stayed on the young man for a while, and Zhuo Huan looked away: "As you are."

Thus, there was a scene where the old Joseph accompanied Fucheng for a test flight with ATR.

Old Joseph: "What is the first situation of the flight test today..." He looked at the flight test form and exclaimed, "Hydraulic system failure? Wow, young people just dared to try. Although this is a simulator, it comes up immediately. I’m getting older and can’t bear the hydraulic system failure.”

Fucheng did not respond to the joke: "How high is it."

Old Joseph immediately straightened his face: "It's 15,000 feet."

"speed?"

"196 knots."

Fucheng raised his eyes to look at the time. He squinted his eyes slightly and held the rudder tightly with both hands: "Get ready, it's going to start...3, 2, 1..."

"boom"

The plane leaned abruptly to one side, and a huge sense of weightlessness swept through the hearts of the two of them. The human body tells the brain at the first moment that they are weightless! However, in the cockpit, the two excellent pilots did not seem to feel this strong sense of weightlessness. Their bodies were pressed tightly on the seats by the seat belts, but the two looked complacent and did not show fear.

Fucheng sternly said: "What's the speed?"

Old Joseph: "No. 176, it falls very fast!"

"What about the height?"

"13500 feet! Vol, what should I do?"

The plane was still falling. Fucheng, who was controlling the plane, used a calm to extreme voice and gave an order to his deputy captain: "Completely restore the scene of the crash. This plane is now under my control until the moment before it hits the mountain, you All you have to do is to flip through the manual, tell me what to do in this situation, and report real-time data to me. When you finally hit the mountain, you have to start putting crazy and trying to save it."

Old Joseph: "Okay!"

"The altitude is 9,500 feet, and the speed is 179 knots."

"5000 feet, speed 172 knots."

"2500 feet, speed 1...V, we hit a mountain."

In the simulator, the aircraft with a malfunctioning hydraulic system is still planting one end to the ground. Twenty seconds later, it crashed to the ground, and a pitch black appeared on the big screen. In reality, however, Fucheng had already let go of the rudder.

Old Joseph wiped the sweat from his forehead: "It's amazing. I know it's a fake. I'm still a little nervous. It's been a long time since I flew the plane. I was caught off guard by such a scene. We prepared in advance. , But even you failed to save the plane. It was too fast, the altitude was not high, and the ground was covered with mountains. The crash was an inevitable ending."

Soon, the door to the simulator was opened, and ATR technicians sent a report of the flight data.

On the A4 paper, several broken lines of data reflect the aircraft's pitch attitude and roll attitude after a failure of the aircraft's hydraulic system. Fucheng sighed and handed the information to the old Joseph.

five minutes later.

The dark-haired young man's calm voice sounded: "...Masha 123 Aviation, take off is allowed. The target of the second experiment, the wing is broken."

boom! boom! boom!

After repeating the experiment time and time again, Fucheng tried all the reasons for the crash that he could think of, and went to simulate the flight test, hoping to obtain a rolling attitude curve similar to that of Masa 123 Airlines. Unfortunately, he tried seven possible causes of the accident and never got a similar result.

Take off the earphones, unfasten the seat belts, and the two of them leave the simulator.

The entire afternoon of the simulated test flight made old Joseph tired. "We have counted all possible causes of failure as much as possible, and we still haven't gotten satisfactory results. It seems that there is no doubt that this strange and unreasonable rolling attitude is the cause of the crash of the plane."

Fucheng was checking the data of the last test flight, and his eyes stayed for a long time on the undulating but fairly stable curve.

"Vol? Vol? What's the matter?"

The next moment, Rumeng wakes up, Fucheng suddenly turns his head to look at the old Joseph. His eyes burned: "All our actions just now restored the behavior of the two pilots, right, old Joseph."

Old Joseph did not understand what he was trying to say: "Ah, yes. The last operations of the two pilots are recorded in the black box, and the rudder found also proves that the two have always wanted to save the plane. We acted according to their actions. Now, so what?"

Fucheng: "The captain has been trying hard to put, and the deputy captain joined him in the end. But until the end, their efforts were recorded by the black box, admitting that they did it, not necessarily the best but they definitely did not. Wrong operation. But now that we really do what they do, the plane will still crash, but it won't cause such a terrible roll posture..."

The voice stopped, as if seeing the fleeting light in the dark night.

ATR headquarters, the world's top pilots took a deep breath and exhaled slowly. In a firm and unquestionable tone, he said: "If an airplane is improved by its pilot, it still rolls violently in the air with an irresistible force and eventually crashes. That can only prove one reason. ..."

Old Joseph Fu Zhimin: "You mean that the hydraulic system fails and the pilot can't control the aircraft?" He immediately denied, "Impossible. The data on the black box proves that the hydraulic system is definitely not completely ineffective."

"Maybe it's not the hydraulic system."

"Um?"

"No matter how the pilots improve the flight attitude, it is useless, because the terminal of all their actions...the tail, there is a problem."

Old Joseph was stunned.

Fucheng had already taken out his cell phone and called Zhuo Huan. Strangely, he just dialed the phone, and Zhuo Huan was connected the next second. The man's slightly hoarse voice passed through the sound hole, mixed with a murmur of electricity: "Hey."

Fucheng: "Teacher Zhuo, how is the tail wing of Martha 123 put together? I suggest checking its tail immediately. I suspect that there is a problem with the rudder on the tail wing."

There was a moment of silence on the phone.

Fucheng was surprised, and was about to speak when he heard Gao Yun's voice from the other end: "Mr. Zhuo, I didn't find it. Will it still be on the mountain? The plane was really crashed, maybe the tail wing was partially broken. It's possible to fall into a ravine or get stuck in any hole."

His eyes widened slightly, Fucheng's lips moved. He seemed to hear the man's exhalation, traveling thousands of miles, as if in his ears.

Zhuo Huan said to Gao Yun: "No, it's definitely a tail wing failure. Now it is suspected that the tail wing is broken. On the way from Zurich Airport to Schaffhausen, immediately look for the tail wing along the road."

Gao Yun: "Yes!"

Zhuo Huan: "Fucheng."

"……Um?"

Zhuo Huan: "Five minutes ago, after the aircraft was spliced ​​to the tail part, it was found that no suitable debris could be found. Perhaps it was not that the rudder on the tail was malfunctioning, but the aircraft... its tail was off."

Suddenly Fucheng didn't know what to say, there was ten seconds of silence on the phone.

"How did you guess it."

Fucheng was silent, "That strange roll attitude curve. Unless a pilot deliberately wants to crash the plane, he will never allow an airplane to roll like that in the air, as if the pilot did not do it. Any effort is the same."

Zhuo Huan was stunned, this answer was something he didn't expect, this is not his domain.

Almost seeing the dawn of victory, the boulder that was in my heart disappeared. Fucheng walked outside the door with the old Joseph, he said casually: "Perhaps... the pilot's intuition?"

On the other side of the phone, Zhuo Huan curled his mouth, said something softly, and then hung up.

The phone was suddenly hung up, Fucheng was a little surprised, he looked at the blackened mobile phone screen.

Old Joseph: "Reid found that the tail is missing? What's this. It's been a month since the accident happened, and we found out that the tail is missing! If it wasn't for the plane crashed too badly, could such an incredible stupid mistake be made? Suppose? I will make documentaries in the future, such as catastrophes in the air. I don’t want to be interviewed. It’s too shameful."

Fucheng gave a soft "um", he remembered something, and raised his head and said: "Old Joseph, you have worked hard, come with me."

Old Joseph waved his hand and laughed, "I think it's much more interesting than airplanes."

Fucheng stretched out his hand: "Good job!"

Old Joseph gave him a high five: "Good job!"

On November 19, 2020, after a 21-day carpet search, the search team finally found the broken tail of Martha 123 in a mountain col.

It fell from an altitude of 15,000 feet, but did not suffer a crushing impact like other parts of the plane, and it remained almost intact.

Schaffhausen, the door of the survey headquarters.

Zhuo Huan led the five UAAG people, standing by the Rhine Falls, waiting for the helicopter to send back the aircraft's tail at the fastest speed.

The helicopter's propeller stirred the air and made a deafening noise. Two steel cables hung a dark metal box under the helicopter and slowly placed it on the ground. Five people from UAAG stepped forward. On the side, the investigator quickly opened the box.

The warm winter sun shines on the tail wing of the airplane.

It has a red pattern on a white background, and that is the emblem of Martha Airlines.

Old Joseph whistled: "Wow, it's so complete. This is probably the most complete part of this plane, right?"

Zhuo Huan squatted down and looked at the tail wing that had several cracks due to the fall from a high altitude. His eyes slid down from the tip, and finally stopped on a few screws at the break of the tail wing.

"It looks very old."

Zhuo Huan raised his eyes and looked at the black-haired young man who also squatted down and looked at the tail wing seriously. He didn't deliberately learn from himself, he just observed the rear wing really intently. After waiting for a long time without waiting for Zhuo Huan's answer, Fu Cheng was a little dazed and raised his head and said, "Ms. Zhuo?"

The Rhine Falls hides this clear sound in the roaring torrents.

After a while, Zhuo Huan raised the corners of his mouth and smiled sarcastically: "Hehe, old? Not just old, but the screw model is wrong, small! Go check it." After speaking, he turned and left, obviously displeased with the result, even I'm not happy to stay one more second.

Gao Yun did not dare to channel: "Small? This screw does not meet the specifications?!" He hurriedly called several investigators, and said solemnly: "Immediately send the tail to the EASA headquarters, especially focusing on the inspection of the screws."

"Yes!"

"Hold on." Before the investigator was about to transport the tail wing, Gao Yun couldn't help but call them. He followed Zhuo Huan's appearance before squatting down to look at the screws: "How can this be seen to be small? Can the naked eye see that the specifications of the screws are incorrect. Is it a human eye microscope..."

Hearing what he said, Lina chuckled, and the old Joseph beside him also laughed.

Su Fei also leaned forward: "I'll take a look, I'll take a look. Oh, how can I see the problem?"

Fucheng stood up and said naturally, "Because he is Zhuo Huan."

Behind him, the man's steps paused for a moment, and Zhuo Huan looked back, his eyes flashed from the young man's thin and thin back. After watching for a while, he turned around again and strode away.

Two days later, the test result of EASA came out.

"The screw used on the tail wing of the Martha 123 flight is a No. 7 screw, which does not meet the specifications. The difference is almost invisible to the naked eye, but it is a smaller model than the original. It seems that there is no doubt that when the aircraft climbs in the air, it is already small. The No. 1 screw suddenly cracked due to long-term work. Therefore, after a few screws were missing, the rear wing could not bear the excessive pulling force and cracked and fell." Gao Yun read the inspection report given by EASA, "This It was the direct cause of Martha 123's accident."

Su Fei raised his hand: "Why are the screws small?"

Old Joseph: "That's another matter. Did the ground maintenance staff get the wrong screws?"

Zhuo Huan: "Then why is it old."

Fucheng looked at Zhuo Huan, he didn't expect the question he asked casually before, Zhuo Huan still remembered.

Gao Yun scratched his head: "Yeah, this is also a problem. Even if the repairer takes the wrong screw type and makes a mistake, he should replace it with a new screw instead of a row of such an old one."

Everyone thought about it again.

"What if these screws were removed from another, older plane?"

Everyone raised their heads and looked at Fucheng together.

Fucheng mused: "A leather bag company that has established cooperation with airlines, flying passenger planes during the day and cargo planes at night, does its best to squeeze the pilots. Their air tickets are sold with the help of Masa Airlines, and their airport access qualification is Masa. From the aviation. You said," he looked at Zhuo Huan, "this leather bag company has only one plane and two pilots. Then naturally they will not have dedicated maintenance personnel."

After a pause, he concluded: "The maintenance of their aircraft is left to others. Now that they have been squeezed to this point, remove the screws from a scrapped old aircraft and use it for waste... Of course."

Zhuo Huan said lightly: "ATR42's tail screw is No. 7."

Fucheng looked at him in surprise.

Zhuo Huan: "I didn't say that these screws must have been removed from an ATR42. It's just that, for ATR series aircraft, only No. 42 screws are used. Mr. Gao, this is what EASA needs to check. Check that leather bag company and check what it is."

All the spearheads were directed at the mysterious leather bag company. Now that the investigation has reached the final stage, only the last step remains.

The moon is in the middle of the sky, and the rapids are turbulent.

Lina walked out the gate of the candy factory and saw her friend standing in front of the Rhine Falls. She walked up and wanted to say "Don't smoke Reid", but when she approached, she was surprised to find that her friend did not smoke!

Zhuo Huan put his hands in the pockets of the windbreaker, looking down at the snow-white foam formed by the waterfall falling from the height.

"I have been in a much better mood recently. I don't think Geral wants his friend to be immersed in painful memories." Lina took out a piece of gum from the bag and handed it over: "But Reid, you don't even smoke. Surprising. Want a piece of gum?"

Zhuo Huan reached out and took it: "Thank you."

"What are you looking at?" Lina followed his gaze, but all she could see was water. "Is there anything special about this waterfall?"

"I'm thinking about one thing."

"Um?"

The air was silent, and no one spoke for a long time.

Lina asked again: "Reid?"

Zhuo Huan chewed the gum with a calm voice. He blew a bubble of gum and chewed it back slowly. Then, in a very light tone, he said casually: "Fusi seems to have a crush on me."

Lina: "..."

"Puff hahaha."

Zhuo Huan frowned slightly and glanced at his friend.

funny?

Lina laughed like this for the first time since losing her friend two months ago. She couldn't help it, even the image of a lady was gone. Finally, she trembled and smiled: "Reid, don't make me laugh. Although I said I will not continue to be sad, but you don't have to... don't have to hahahahaha..."

It doesn't have to be the case.

Zhuo Huan let out a soft voice.

Lina finally stopped laughing: "Are you serious?"

Uncle Zhuo chewed gum, blew a bubble, and ignored her.

Lina tried to be serious: "Ahem, I have to tell you something, Reid. Every member of UAAG I regard them as family members and my most important partners. Therefore, after you decided on the list of members, I quietly investigated. Every one of them. Don't worry, it's just a little information that has probably been investigated, and they haven't violated any of their rights of freedom."

"So?" Uncle Zhuo raised his eyelids.

"It stands to reason that I will not investigate Fu's family situation, let alone his romantic relationship. But because he was a top student since he was a child, the only time he recorded on his file was in high school, so I took a curious look. Do you know the reason for remembering?"

Uncle Zhuo blows bubbles.

"When I was in the third year of high school, I had a love relationship, and the object was the school flower of that school. Near the college entrance examination in China, he fought for his girlfriend and other classmates, so he was remembered." Suddenly, Lina suddenly couldn't bear it. Hit the handsome and proud face of his friend: "After the college entrance examination, the two broke up. As far as I know, he likes that girl very much. So..."

"Reid, Fu is not gay."

"Snapped"

The chewing gum bubble was suddenly blown and stuck to his lips.

"Ah."

Uncle Zhuo let out a disdainful hum from his nose, chewing gum, and turned around and walked into the investigation headquarters.

The author has something to say:

Zhuo Anxi: What I want to say next, don't be afraid!

Lina: Don't worry, Mr. Zhuo, I have received professional training and I will definitely not be afraid.

Zhuo Anxi: Fucheng has a high probability of crushing me! [Fuchengcheng: Meow meow? ? ? 】

Lina: Puff.

Zhuo Anxi:? why are you laughing?

Lina: Mr. Zhuo, I think of something happy.

Zhuo Anxi: What's happy?

Lina: I have a friend who is so narcissistic hahahahahahahahahahahahahahahahaha...

For the convenience of reading, I have handed over all the air crashes in Europe to EASA. I won't write anything like AAIB, so that you don't feel dizzy at all abbreviations. In addition, this article sets up McFlys in the air, alongside Boeing and Airbus, the world's three largest aircraft manufacturers.

The prototype of this crash is MINX27100 flight and JAL flight 123. If you are interested, you can search the documentary to see~
