The exposure of media public opinion was like a raging fire, and NTSB and GCAA were placed on the grill to roast.

While responding to media reporters' snooping and interviews like a storm, both parties accelerated the experiment progress. Three days later, NTSB and GCAA obtained experimental results almost at the same time.

While looking through the experimental report, Maiha said: "From the fall of the fragments on the flap, the experiment estimated that 80% of the possibility is that the aluminum alloy peeling on the upper surface of the flap is peeling off, and 20% of the possibility is that the flap flap is directly falling off. The Boeing 777 aircraft used by the Ahanghai 411 was just launched for four months when the air crash occurred. The possibility of metal fatigue is extremely low. It is initially suspected that it may be a repair error such as screws."

As soon as he finished speaking, the representative of Ahanghai's side immediately looked calm and said, "Ahanghai has never made any mistakes in repairs. We would rather let an aircraft never take off than have to repair it in a hasty way!"

Maiha looked up at him: "This is just a suspicion. It may not be that Afghanistan made a deliberate mistake. In 1990, British Airways 5390 aircraft accident, British Airways' maintenance department used screws 2 mm smaller than the standard size when repairing the windshield of the aircraft by only the naked eye. In the end, the plane was completely off at a high altitude, and the captain was sucked out of the cockpit. If it was an accidental mistake in maintenance, it was not impossible."

Representative Ah Hang still disagrees with Maha's point of view, but he cannot completely reject the other party's judgment.

The wreckage of the plane has been destroyed more than 20 years ago.

Maiha could not find evidence to prove that Ahang's maintenance was wrong; similarly, Ahang couldn't find evidence to prove that he was not wrong.

At this time, NTSB director Lovens began to report on the experiments on the broken blades of the aircraft engine. He stood up: "After conducting 76 actual aircraft experiments on the Rolls-Royce Trent 800 engine, the following conclusions were drawn."

"First, when the heat resistance reaches 1050°C, at a speed of more than 32 knots, the experimental material can pass through the fuel chamber almost without loss."

"Secondly, the Mohs hardness of this experimental material reaches more than 4, or more than 4.25, which can resist the internal pressure of the engine."

"Third, experimental materials with a ductility of 3.2N/mm can pass through the fan blades of the low-voltage module in front of the aircraft almost without loss under certain circumstances."

Lovens raised his head: "The above are the four-day experimental data and results of NTBS. There are not very few physical materials that meet these properties. However, it is very difficult to reach a relative speed of more than 32 knots and not be shattered by the fan blades of the low-voltage module. My suggestion is to find aircraft that were in the same airspace or higher as the Ahanghai 411. The engine exploded suddenly during the takeoff process. At that time, there were many aircraft that also took off from Dubai in the nearby airspace."

Hearing this, everyone looked at Lovens.

Old Joseph: "You mean, maybe some parts were dropped from other planes, and by that coincidence, it just flew into the engine of the Ahanghai 411?"

Maiha: "The possibility is too low, what a coincidence it is!"

Lovens asked back: "Isn't the air disaster a coincidence that ended up causing it?"

No one can refute his words.

There was silence in the conference room.

Lovens looked up at Zhuo Huan: "Patrick, what do you think."

Zhuo Huan pondered for a long time, and he looked at his member. Old Joseph shook his head at him. Obviously, it was not convincing whether it was the reason for "an airline repair error" of Maiha or the reason for "a part fell from the sky" that Lovens was very unconvincing. He looked at Fucheng again, and Fucheng also looked at him seriously and shook his head gently.

Zhuo Huan withdrew his gaze and tapped his fingers rhythmically on the table: "Let's find the survivor again."

Lovens was stunned: "We have seen Yamira Betty's witness report many times, and she has repeated it to us many times. Do you still need to find her again? She probably can't provide any more clues."

Zhuo Huan: "Look for other survivors who were also on the plane at that time. There were more than 100 survivors. In terms of probability, it should not be the only one who felt the abnormality."

Soon, GCAA investigators searched the accident information and found all the information about the survivor of Ah Hang 411.

However, twenty-three years have passed, and many survivors have passed away for various reasons. There were more than 100 passengers who survived that year, but now only 63 people are left. Half of them are unwilling to recall the scene of the air crash, or because of the sequelae of the accident, they selectively forgot everything that happened during the air crash.

Without further ado, the three parties cooperated and investigators began to conduct video inquiries on 35 survivors who were willing to provide testimony and recall the air crash.

That night, the survey headquarters and conference room.

Fucheng stood in front of the whiteboard, and he looked at everyone, and finally his eyes met his companions. After nodding, he said, "Then let's review all the happenings. First of all, unfortunately, the black box of the Ahanghai 411 air crash was completely damaged in the explosion after the crash. At the same time, because the nose hit the ground, all three pilots in the cockpit were killed. So no one knows what the plane had experienced when the crash occurred. So in this case, we can only confirm the approximate flight status through interviews with survivors."

This was done twenty-three years ago by NTSB investigators.

There is no black box, no video record, and no pilot. So how do you know what an aircraft that almost exploded to pieces went through before it crashed?

Only ask survivors, piece together the truth from their sporadic memory.

Fucheng continued: "At 10:31 am on July 11, 1998, AirAsia Flight 411 passed the tower and took off from Dubai International Airport and flew to Sydney. Everything went well when the plane took off. It was sunny at Dubai at that time, but a tropical air current was hovering over the east of the airport."

"The aircraft flies smoothly and the communication with the tower is also stable. When it flies near the tropical cyclone, it experiences the inevitable bumps. Afterwards, the NTSB interviewed other pilots in the same airspace and confirmed that this tropical cyclone would only cause bumps at most, but would not affect the normal flight of the flight."

"During the bump, according to the testimony of witness Yamira Betty, she saw a piece of debris flying out of the flap of the right wing of the plane."

Joseph Older, frowned and asked, "How likely is the surface material of the aircraft falling off and causing engine damage?"

Fu Cheng paused, looked at him, his voice calmly: "What do you think."

Old Joseph shrugged and said helplessly: "I'm just kidding."

This is probably less likely than if Emirates went bankrupt today.

Fucheng continued: "After Amira Betty saw the fragments flying out of the flap, she recalled that within three seconds, she heard a bang. The other passengers agreed with her testimony. They all saw the fragments flying out of the flap, but they all heard a huge explosion. Afterwards, it was the explosion of the engine."

"After the explosion, the plane began to move irregularly and violently, and about five minutes later, it crashed into the desert next to the Persian Gulf."

"The above are the memories of all survivors."

After saying that, Fucheng looked at the man sitting in the front.

Zhuo Huan turned his pen with one hand, looked down at the ground, and pondered silently.

After silence, Fucheng said, "Teacher Zhuo, what do you think?"

Zhuo Huan raised his eyes and looked at him. After looking at each other, Zhuo Huan stood up and walked to the whiteboard. Fucheng walked down very naturally and sat in his seat.

Zhuo Huan stood beside the whiteboard, and he glanced at him, raised his pen and pointed at Lovins: "The possibility of foreign flying objects is directly PASS."

Lovens was stunned and said in surprise: "Why? This is also a possibility. Although it sounds a bit absurd. But as far as I know, Dubai International Airport was very busy that day, and took off in five minutes and landed more than 70 planes."

Zhuo Huan's mouth showed a sarcastic smile: "Are you questioning your boss's ability? If there is really an alien flying object that gets into the engine, then no matter what it is cracked due to the explosion, your boss can find it out from the endless sand and press it to death on the chain of evidence. Levi Andrew can even find fan blades that break into such and conduct experiments, and can't find an external material that does not belong to this plane?"

Lovens was speechless.

Zhuo Huan continued: "Ahang's maintenance issue will not be mentioned for now, but only for the final reference. First, we must clarify one problem. The thing that tear apart the fan blades of this Boeing 777 must come from itself."

Fucheng thought for a while, raised his hand and asked, "Does it only come from the engine?"

Zhuo Huan looked at him: "Not necessarily."

Fucheng was silent for a moment and spoke: "Last year, when we investigated the JAL 917 air crash, an invisible culprit appeared. It was electromagnetic waves. If Mr. Andrew, the ace investigator of NTSB, combined with everyone present today, could not find a murderer who could cut the fan blades and flaps at the same time... Could it be that it has disappeared, or it was invisible at the beginning?"

After Fucheng finished speaking, Zhuo Huan was stunned.

At the same time, Joseph, Lovens and others also showed surprise.

There were rustling discussions in the conference room.

Zhuo Huan looked at Fucheng with sharp eyes: "Reason."

Reason, the reason why this view was suddenly raised.

Fucheng looked back at him seriously and gave the answer: "I just think that if I was investigating a top-notch, perfect airplane air crash, its low-pressure fan blade located in front of its tailbone suddenly broke, and afterwards so many people searched together, they could not find the culprit. Then... when you rule out all impossible situations, no matter how unbelievable the rest, it is true." The voice stopped, Fucheng seemed to want to say something, but he shut his mouth and didn't speak again.

Zhuo Huan's gaze stayed on him for a few seconds, then he looked at everyone sitting at the table and said, "It is not impossible for the invisible murderer. The next investigation should be started from this aspect."

***

In UAAG's office, everyone began to discuss the possible causes of the accident.

Su Fei said without hesitation: "Electromagnetic waves. JAL 917 was affected by the aurora, which caused electromagnetic disorders in the aircraft's MCD magnetic chip detector, and finally affected the aircraft's telex system."

Fu Cheng shook his head: "It can't be electromagnetic waves. Electromagnetic waves may cause engine abnormality, but they will never let the skin of the aircraft flap fall off." After a pause, he added: "The flap is definitely caused by an objective and visible physical cause."

"Your words are inconsistent."

Everyone turned their heads and looked at the man sitting by the window.

Zhuo Huan stood up while chewing gum, and pulled his chair between everyone with a calm expression.

Lina was a little surprised: “Reid?”

Mr. Zhuo sat down on the chair casually, raised his legs, and looked at Fucheng: "Your proposal is the invisible murderer. But you also said that the fall of the flap fragments is a physical effect visible to the naked eye."

Fucheng's lips moved.

Old Joseph came up with a reason: "Maybe, these two things really have no connection, it's just a coincidence? The fall of the flap fragments may be due to the repair error of Ahwan, or it may be an extremely rare material break. To put it simply, it's just that Amira Betty misread it, or... all of this was made up. She didn't see any flap peeling, she just didn't want to be deported, so she made up this lie."

The office suddenly became quiet.

After a long time, Zhuo Huan sneered: "This is the last possibility."

Su Fei: "That's not electromagnetic waves, what is it?"

Joseph Older thought for a moment: "When investigating the 917 air crash last year, we once said that the 2008 British Airways 38 air crash was ice slag blocking the oil pipeline, which eventually led to the engine shutdown. Of course, this accident happened in Dubai in the summer, and ice was absolutely impossible. But is it possible... the culprit was water?"

Fucheng shook his head: "Water, even ice, cannot be cut through the fan blades of the aircraft engine."

Although Lina cannot insert these topics, she is full of love for the planes. Otherwise, she would not have resigned from the United Nations and came to UAAG. She poured a cup of coffee for everyone and said with a smile: "Don't worry, twenty-three years have passed, and these days are not bad."

Su Fei: "The invisible murderer is not water, not electromagnetic waves... is it the temperature? The extremely high temperature?"

Zhuo Huan glanced at him and sneered in his nose: "It's just that you can talk nonsense? How high is the temperature that exceeds 1000℃? Oh, the fuel chamber of a Trent 800 engine can reach a high temperature of 1000℃ by itself."

Su Fei: "..."

"Then what can I think! If it wants to be invisible, it also needs to be able to damage the fan inside the aircraft and the flaps outside the aircraft at the same time! Does this thing have three heads and six arms? Then why does it only attack the right wing and the right engine? Do you look down on the left engine?"

Fucheng was suddenly stunned, and he said in surprise: "No, it is not that it does not attack the left wing and the left engine, it is that its influence range is only on the right."

Old Joseph also suddenly came to his senses, and he quickly said to Lina: "Lina, can you help me print a 3D structure diagram of the Boeing 777?"

Lina smiled gently and said, "Of course."

But Zhuo Huan said, "It's too slow."

Everyone looked at him in surprise.

Zhuo Huan turned sideways, stretched out his hand to take a blank piece of paper from his desk. He held a pen and quickly drew a smooth curve on the white paper. Then, another curve spread on the white paper at an extremely fast speed. The black ink kept smudged on the white paper, as if there was no need to think. In just thirty seconds, a hollow Boeing 777 appeared on the white paper.
To be continued...
