During the investigation of aircraft accidents, there are not many such things as investigators competing for aircraft, but not many.

Most plane crashes do not fall so much. In many cases, they can even maintain an almost complete shape of the plane, and it is not difficult to put them back. However, planes like Martha 123 that hit a mountain at high speed and ended up falling to pieces are so difficult to put them together.

However, Zhuo Huan was not kidding.

The next day, the investigation team began to reconstruct the skeleton model of the aircraft.

The aircraft is not a puzzle, and can be pieced together with pieces. The aircraft is in a 3D three-dimensional shape. If you want to piece together a complete plane, you must first build a complete steel bone for it. Just like building a house requires laying a foundation, the investigation team took three days and spent more than 30 investigators and workers to finally build the steel bones of the aircraft.

ATR's technicians also arrived in Schaffhausen at this time to provide technical support to the investigation team: no one knows their own plane better than them.

The grand career of fighting for the plane has slowly unfolded and is destined to be unable to be achieved overnight.

On the other hand, Lina also found more than a hundred passengers who had taken Martha Flight 123 through the airport and airline. She contacted these people online and offered to bear all travel expenses. In the end, more than 30 people agreed to come to Schaffhausen to be interviewed by the investigation team.

In the warehouse of the candy factory, the debris of the plane that once had been placed all over the ground were now all gathered aside, replaced by a huge steel aircraft skeleton. It spans most of the warehouse and occupies the most central position of the warehouse. Dozens of investigators and ATR technicians took the debris and gestured on the skeleton of the plane, finally confirmed, and then pieced together the wreckage.

Lina came to the warehouse, and she found Fucheng in the crowd and waved to him.

Fucheng walked to the warehouse door and Lina said, "Five passengers have arrived. Fu, I want to ask you to interview with me."

Fu Cheng thought for a while: "Don't you call Teacher Zhuo?"

Lina asked in surprise: "Do you think Reid is suitable for such an occasion?"

This was reasonable and well-founded, and Fucheng could not refute it at all. He put down his work and went to the office building of the candy factory with Lina.

Since UAAG bought the candy factory, it has naturally become the investigation headquarters. The two came to the fourth floor, and there were five people sitting in the corridor, including men and women, old and young. Lina walked up and said a few words in German. Then she walked into the office with a young girl.

The gate was closed gently, the girl sat opposite, Fucheng and Lina sat on the other side.

After entering the house, the girl looked around with curious eyes. Not everyone has ever been on a plane, and most people have never had any relationship with air crashes in their entire lives, and they will not come into contact with the plane accident investigation team.

This is a spacious office with various materials and instruments in a mess. A whiteboard inside the house is full of words in red and black markers, and someone's names include Martha Airlines and Martha 123. Next to these words are photos of the two pilots.

Lina turned on the recorder: "Hello, when did you take Martha Flight 380?"

The girl immediately withdrew her gaze and sat straight: "Well, cough, I flew from Berlin to London a month ago..."

One morning, more than a dozen people came one after another.

It was like a passerby in the world. They walked through the door of the office, left some faint impression of Martha 380, and then left in a hurry.

In the evening, all thirty-six people had finished interviews. Fu Cheng sorted out the interview information, and the sound of the chair's feet moving came from his ears. He turned around and looked at Lina standing in front of the whiteboard, looking up at the blonde young man with a bright smile.

Her hands held the recorder tightly, staring at her friend's carefree smile. Hot tears filled her eyes and finally burst out. She suddenly reached out to cover her mouth without letting the crying pass through her fingers.

Fucheng's lips were twitching, and he was about to comfort him, Lina: "Let me be quiet alone, Fu."

Fucheng silently: "Lina, I'm sorry."

Staring at his close friend on the whiteboard, Lina was hoarse and said, "He never told me that his work was so hard. He never said it..." The crying could no longer be suppressed and she vented from her throat.

Lina cried bitterly, and Fucheng walked out of the office with the interview information, leaving her a quiet space.

Inside the door is the woman crying desperately and collapsed, and outside the door is a depressing silence.

Fucheng closed the door, and he turned around and suddenly stopped.

After a while, Fu Cheng whispered: "Teacher Zhuo, when did you come?"

The sunset passed through the window at the end of the corridor, sprinkled into the room, falling on the concrete floor, radiating a warm and cool glow. The man in a thin coat stood leaning against the wall, his hands in his pockets, his head slightly lowered. He seemed to be eating gum in his mouth, and his lips were undulating due to the chewing movements.

"It's only been five minutes." After a pause, Zhuo Huan looked at him: "How is the interview?"

Fu Cheng was silent for a moment and handed the information in his hand to the other party.

Zhuo Huan took it and glanced roughly. A sneering sound came from his nose. He handed the information back to Fucheng and turned around and left: "Let's go, go back and play the plane."

Fucheng hesitated for a while, but still followed.

Under the glow of light, the two walked side by side and left the quiet corridor.

The data was placed in the database of the investigation headquarters by Fucheng. When the truth was revealed, they would be written into it when the investigation report was written.

Six hours ago, in the office, the girl said this in English—

"I was a little late when I boarded the plane. I just sat down and went to the cabin to explain the usage of seat belts to us. This is a low-cost airline, and of course there are no LED displays like other large aircraft, so this kind of safety reminder has to be said by people. However, this is the first time I have seen a pilot doing this, so I am deeply impressed."

The old man said this in German—

"I was the first to board the plane. Maybe I went a little early. I saw the captain repairing the chair. He was surprised when he saw me and quickly explained to me that the chair was fine, but there was a screw loose and he wanted to twist it."

The boy recalled and said—

"Because I forgot to get something, I returned to the plane. I saw the captain and the deputy captain dismantling the seats. I was so surprised that they helped me find my lost bag. When I left, I turned around and saw them carrying screwdrivers and still dismantling the chairs. Why should I remove the chairs? Are those chairs too old to change?"

In the deadly office, Fucheng looked at the puzzled boy.

“…Yes, because those chairs are too old, they need to be replaced.”

Why remove the chair?

Because after sending off the last round of guests, they will serve as cargo pilots and transport goods.

Therefore, removing the chairs as much as possible can leave more space to load cargo and increase transportation profits. This is the requirement of the airline. After sending guests away every day, remove all of the forty seats and move them into the luggage compartment. Wait until you arrive two hours in advance the next morning and install the seats one by one.

Day after day, repeat the same thing.

This is what Lyon Lorraine and Geral Truffaut do every day.

At 8 o'clock in the evening, everyone was continuing to fight for planes in the warehouse. Lina walked into the warehouse with red eyes. She shouted Gao Yun out and said something. When Gao Yun came back, Fu Cheng asked him: "What did Lina say to you?"

Gao Yun's face was not very good, and he sighed: "Lina told me that EASA headquarters has made a conclusion and issued a certain warning and punishment for Martha Airlines. But there are no other punishments. Since Martha Airlines can cooperate with the bag company and fabricate a Martha flight 123 out of thin air, there must have been legal consultation. Their behavior must be completely legal and no one can sanction them. So Lina just asked me, is it really the only way to do this in the European aviation law... I told her, yes, unfortunately, this is the ending."

Speaking of this, Gao Yun smiled bitterly: "After I immigrated, I sometimes felt that the Western system was very good, and sometimes I felt that it was extremely ridiculous. The law always serves class personnel, and this class is a natural barrier that we will never get through in our lives. If this happened in China, at least Martha Airlines would not be so unscathed, and we would not even find a person who needs to be held responsible."

Fucheng naturally couldn't answer this answer.

Two days later, Su Fei returned to Schaffhausen with the repaired black box data.

"The black box was a little damaged when the plane crashed into a mountain and exploded, but the problem was not serious, so it was basically repaired. When I was at the headquarters of ATR in France, I had separated the flight data and the cockpit call records and divided it into five audio tracks. Let's look at the flight data first, or listen to the call records first?"

Su Fei didn't know that Zhuo Huan had denied the pilot's mistake, the cause of the air crash. It may be the reason, but it is definitely not the main cause.

Zhuo Huan stood beside the big screen: "Look at the flight data."

Su Fei: "OK!"

The punk boy's fingers pounded on the keyboard, and soon, the complete flight data curve was projected onto the large screen.

The flight data curve of the aircraft's black box includes multiple parameters such as the pitch attitude, rolling attitude, and lateral overload of the aircraft. The ATR72 is an old aircraft produced in the 1980s, so its black box records very few parameters, with only 11 records.

If it is a movie, the investigator will carefully check from the first second of the black box record to find out whether an abnormality has occurred. However, this is reality.

Almost the next second when the flight data curve is projected onto the large screen, four or five sounds sound at the same time—

“Rolling posture?!”

Fu Cheng stood up and walked to the big screen. He looked at the rolling posture data carefully. After a while, he turned to look at Zhuo Huan: "I have never seen such rolling data. In fact, even when military fighter jets perform exercises, they rarely do such high-risk rolling actions. It is absolutely impossible for civil aviation passenger planes to make such rolling actions artificially."

Gao Yun immediately asked a question: "Yesterday, the investigator and I had completely checked the right engine and confirmed that there was no abnormality in the right engine. Now the black box data is also clearly displayed. It is not an engine problem, and the engine is intact until the crashed engine is intact. So what is going on with this strange rolling posture?"

Zhuo Huan rubbed his chin, and his voice was deep: "Is there something wrong with the hydraulic system?"

The ATR-72 uses a traditional hydraulic system.

The pilot controls the aircraft through a hydraulic system. The hydraulic system is equal to the airplane's blood vessels, which transports blood (the pilot's instructions) to every cell in the aircraft. If there is a problem with the hydraulic system, the pilot will not be able to control the aircraft at all, and the crash is an unavoidable ending.

Fucheng suddenly thought, "Will it be a special downward airflow? According to the weather on the day of the crash of Martha 123, there were thunder clouds twenty kilometers east of Zurich Airport. Although the route of Martha 123 does not pass through the thunder clouds, perhaps due to special reasons, it affected the flight of the plane?"

Gao Yun followed Fucheng's words: "You mean that once the downward airflow affects the rolling posture of the aircraft, the aircraft overturns. First, because the aircraft has just taken off and the altitude is not enough, the pilots have no time to adjust; second, these two pilots are indeed too young, have insufficient experience, and have average flight skills. Coupled with long-term work, they are tired of driving and cannot respond well, and are in a hurry, which leads to the plane crashing into the mountain?"

Fucheng turned his head and looked at Zhuo Huan: "Teacher Zhuo, what do you think?"

Zhuo Huan stood in front of the big screen, his eyes fixed on the plane's rolling data curve.

After a long time, he said, "There are many possibilities. Fucheng, if you go to check the weather and weather information of that day, you must determine whether the thunder clouds on that day have caused downward airflow and whether it can affect the flight of the plane twenty kilometers away."

Fucheng nodded: "Okay."

"As for the others..."

Gao Yun and others suddenly became nervous.

Zhuo Huan: "Put the plane first."

Everyone: "..."

As if he didn't notice the resentful sight behind him that was almost condensed into substance, Mr. Zhuo was very calm and said to Su Fei: "Listen to the cabin call record."

The office, which was originally a little noisy, suddenly became quiet because of this sentence.

Everyone held their breath and waited to hear what the two pilots had said before the crash and what warnings the plane had given.

More than ten minutes later, Zhuo Huan closed his eyes and announced calmly: "The cabin call record has no effective reference and is not needed as investigation data for the time being."

No one questioned his words, because during the thirteen-minute conversation, the two pilots said almost meaningful words. Apart from the final near-desperate shouting and the crazy roar that wanted to correct the plane's posture back to level, and was helpless, there were only a sound of "NO".

No, no, no...

The last words of each victim of an air crash are always surprisingly similar.

There is no memory of the past, nor a rational analysis of the cause of the accident. When the clouds and mists break open, they see the mountain wall that is so close, and all they can think of and blurt out is this sound of no sound.
To be continued...
