Xu Xian slowly stretched out his right hand and hung it flat in the air. After waiting for a while, a very fine layer of dust was spread on his fingertips.

"What is this..." Xu Xian muttered to himself. He had never seen such a thing before, especially on a plane at an altitude of 10,000 meters. However, his sixth sense told him that there seemed to be something like this.

Something big happened!

At this time, after getting started, the passengers' dissatisfaction began to pour out like boiling steam that was difficult to suppress. The crew's long-term inaction finally made the passengers' anger that had been accumulated for a long time finally burst out.

Xu Xian did not follow the other passengers to vent his emotions. Acting like this and forcing the crew members in this way had no meaning except adding unnecessary pressure to the crew members.

Of course, Xu Xian didn't think the other passengers were stupid. This was just the normal behavior of ordinary people and a reasonable reaction based on the behavior of the crew.

Now the plane is as smoke-filled as the Genting Palace, and even breathing is difficult. However, no crew member can give a convincing explanation or measures to deal with it. It just flies forward as if nothing happened.

Anyone who touches it will be dissatisfied! This is disrespect for life.

Perhaps because they were too excited, many passengers inhaled more smoke, and there was a burst of coughing. In an instant, the entire cabin seemed to have turned into a respiratory ward of a hospital, and no one could live in it.

Coughing and wheezing sounds.

At this time, an extremely terrifying thought came to Xu Xian's mind. The information about the smell of sulfur was really iconic.

He slowly turned his head and looked out the window. The outside world was as dark as falling into a sea of ​​ink. In the darkness that almost swallowed everything, there was a faint red dot, as if the bloodthirsty eyes of a giant beast were watching.

Looking at this plane, it seems that it can be swallowed up at any time.

This faint red dot is the aircraft’s navigation light!

Navigation lights are a set of signal lights installed on the aircraft for air traffic to detect each other during navigation and to determine the flight direction. It is stipulated that the aircraft should be equipped with navigation lights on both wing tips, and it is stipulated that the left wing tip has a red light and the right wing tip has a green light. Of course

, customarily, there is also a white light above the wingtip of the aircraft's vertical tail.

The flight crew can identify the relative position of the opponent's aircraft and their own through the combination of visually observed lights.

Aircraft navigation lights are different from strobe lights. The navigation lights are always on instead of flashing. However, when Xu Xian looked out through the window, not only was the light very dim, but it also flashed irregularly!

This is one of the manifestations of an aircraft entering the clouds! Due to the obstruction of clouds and fog, the lights dim. At the same time, due to the unevenness of clouds and fog, the lights appear irregular light and dark changes.

No! If you go by Xu Xian's conjecture, what's outside shouldn't be considered clouds, but something even more terrifying, the culprit of everything.

Xu Xian stood up suddenly. He needed to verify the last thing to conform to his conjecture!

He passed through first class and business class and went straight to the front cabin cabin.

In the front cabin cabin, the flight attendant and the second flight attendant were wetting small towels and preparing to distribute them to passengers. The function of wet towels in filtering smoke is much better than dry towels.

"I don't know!" the flight attendant sighed: "The cockpit didn't talk about the flight altitude."

Xu Xian's eyes flashed, and he breathed in increasingly thicker smoke in his nose. He suddenly raised his head and looked directly at the flight attendant: "I want to talk to the cockpit!"

The steward's lips pursed slightly: "Are you flying?" At this time, there was no need to hide it, Xu Xian nodded immediately.

The flight attendant breathed a sigh of relief: "Have you brought your ID?"

Xu Xian: "No! I was traveling for personal reasons and didn't bring my ID."

The flight attendant frowned. She was a little unsure about this situation without documents: "I'll ask for permission to get out of the cockpit."

Under normal circumstances, the flight attendant would never let someone without ID speak to the cockpit. However, now that the passenger seemed to know something, she felt it was necessary to let him communicate with the cockpit.

Moreover, her previous phone call with Chen Qi made her feel that the two people in the cockpit were not that reliable. Many passengers were making noises in the cabin, and their flight attendants were trying their best to comfort them. However, it did not mean that the flight attendants did not want to know.

What exactly happened? So far, even their flight crew knows nothing about the details of the situation. In the few calls she had with the cockpit, the cockpit did not give her a reasonable explanation.

If it wasn't her duty, she really wanted to sternly question the two people in the cockpit.

"I even need to ask for permission to talk to the cockpit? It's not like going in!" Xu Xian said speechlessly. He doesn't have a certificate now. If he needs to ask for permission to enter the cockpit, he can understand. Now, he just wants to talk to the cockpit.

You have to ask for permission even if you say a few words, it’s too careful!

Is it possible that I can kill people through wires?

"Sorry, company regulations..." Before the flight attendant could finish his words, a harsh commotion suddenly broke out in the cabin behind.

The attention of everyone in the cabin was instantly attracted. The safety officer reacted the fastest, lifted the curtain, and ran towards the economy class. He identified that the source of the noise was in the economy class.

Xu Xian's eyes suddenly glanced at the window at the cabin door. Through the window, he saw a faint blue light. At an altitude of 10,000 meters, this strange blue light seemed particularly creepy.

Xu Xian turned his attention to the cabin corridor as if guided. At this time, the curtains between the first class and business class had been opened, and his line of sight was unobstructed. He could directly see the scene in the economy class.

Xu Xian originally thought that the sudden commotion was that passengers in economy class were making trouble again. However, things were different from what he thought. A large number of passengers lined up on both sides, lying on the cabin windows, looking outside.

Vaguely, Xu Xian discerned among the noise that the word that appeared most frequently was...fire!

The hairs all over Xu Xian's body suddenly stood up. He put aside the conversation with the cockpit for the time being and ran quickly to the economy class. He had a bad feeling.

In the cockpit, Chen Qi panicked for a moment after the old instructor fell unconscious. He pushed the old instructor a few more times. After getting no response, his head was buzzing and he suddenly lost his bearings.

His eyes were full of panic, and there was no trace of the calmness of a professional pilot. He usually carried the name of a pilot, but when had he actually done the actual work of a pilot? It was all because of the flattery of the captain and instructors.

Now when the problem arises, the teacher has lost consciousness, and he begins to realize that he really can't do anything. In other words, the little knowledge he has cannot be used in such a panic, and he has lost it.

The thinking ability that a pilot should have.

No matter what happens now, we must make a backup landing. Even if there is no smoke, just because the instructor loses consciousness, it does not meet the minimum crew configuration standards, and we must make a backup landing first.

After having some ideas, Chen Qi felt calm and contacted Shangdu area control: "MAYDAY, MAYDAY, MAYDAY, Shangdu control, Chimelong 5677, there is unexplained smoke in the cabin, the captain is incapacitated, please apply for landing at the nearest location."

In the current situation, the plane was filled with unknown smoke, the captain was unconscious, and the situation was unknown. The highest priority landing sequence was required. Therefore, Chen Qi directly declared an emergency in order to land in the shortest time.

There was nothing wrong with this at first, but what Chen Qi responded to was the sizzling noise of electricity. Among them, there was a vague human voice, but Chen Qi couldn't hear it at all.

Chen Qi thought that Shangdu Control did not hear it, so he repeated it again: "Shangdu Control, Chimelong 5677, there is unexplained smoke in the cabin, the captain is incapacitated, please apply for landing at the nearest location!"

In the Shangdu Regional Control Room, the controller yawned. At seven or eight o'clock, when he has just finished dinner, he is most likely to get sleepy. Moreover, there are only two planes in the area under his jurisdiction, and there is nothing important at all. It is really boring.

tight.

Suddenly, out of the corner of his eye, he saw an aircraft light up on the radar screen, which was a sign that the flight crew was talking. At the same time, intermittent calls sounded in his earphones: "MAY...56

.....original...landing..."

This call was not only extremely noisy, but also very discontinuous, making it difficult to hear clearly.

The controller glanced at the radar screen, which showed the plane's flight number, and proactively asked: "Um, Chimelong 5677, please repeat that, it's causing interference."

Radio communications between the controller and the aircraft are often interfered by different factors, causing the signal to become unstable. It is not uncommon for the signal to be interfered, and the controller does not pay much attention to it.

If the signal is interfered, just ask again. It's not a big deal.

However, what the controller asked about Chimelong 5677 fell into Chen Qi's ears, which was almost meaningless electrical noise.

Chen Qi repeated it again, but when it was transmitted to the controller, there was another intermittent and unstable signal.

"Chimlong 5677, there is still a problem with the signal. Please try another transmitter." The controller said.

If there is a problem with the continuous communication signal, the controller will usually ask the flight crew to try changing the transmitter. On the aircraft, there are a total of three different transmitters, and it is rare that all three transmitters have poor signals.

However, to Chen Qi, the controller's words sounded like a continuous noise of electricity. However, this time it was a little quieter, and he heard one or two Chinese characters that seemed to be present or absent.

However, even so, it is still meaningless.

"What the hell?" Chen Qi just wondered if he didn't look at the almanac when he went out today? The captain can't be counted on, and the flight attendant is useless. Now the contact person has banned applying for priority landing rights. It seems that the whole world is against him.

At this time, Chen Qi showed that his professional skills were not solid. Let alone whether the flight attendant is useful or not, there are corresponding procedures for the captain to be disabled and unable to contact control in an emergency. Chen Qi is now feeling sorry for himself.

It only shows that his own foundation is too weak.

And this kind of unexplained smoke is still unclear. No matter it is the engine fire alarm, APU fire alarm, cargo compartment fire alarm or wheel well fire alarm, there is no warning. However, even in the absence of fire alarm warning, the entire cabin is filled with

There was smoke that was almost visible to the naked eye, and he didn't know where the smoke came from.

The funniest thing is that the captain was choked by the smoke, which is the most ridiculous thing in the world.

"Shangdu Control, Chimelong 5677, how many of you will listen to my signal?" Chen Qi did not give up and continued to call Shangdu Regional Control.

Once again, the low-quality communication of the Chimelong flight made the controller a little annoyed: "Chimlong 5677, this transmitter is not good either, let's get another one."

Not long after, the communication signal of Chimelong Airlines was still extremely poor. At this time, the controller could no longer bear it and contacted another flight to ask it to help convey: "Blue Sky 9883, tell Chimelong 5677

Wait. There is a problem with his transmitter. Ask him to replace it quickly."

When encountering such persistent poor communication signals, it is quite common to use other aircraft as relay stations.

The crew of Lantian 9883 was very cooperative and immediately conveyed the request of Shangdu Control in an obedient manner: "Chimlong 5677, Shangdu wants you to change your transmitter. The signal of your current transmitter is not good."

As a result, the crew of Lantian 9883 waited for a long time, but there was no response.

"Shangdu, do you think there is a problem with the communication system of Chimelong 5677?" At this time, even if he was slow, he could tell that there seemed to be something wrong with Chimelong 5677.

When Shangdu Controller spoke, he spoke to all channels. Therefore, if Shangdu kept asking Chimelong 5677 to replace the transmitter a few times, the crew of Lantian 9883 also heard it. The controller said it so many times, but Chimelong’s crew still maintained the

As for the communication quality, either Chimelong's crew couldn't hear the control voice, or all three transmitters of Chimelong's aircraft were out of service. Regardless of the reason, it didn't seem to be a good thing.

Moreover, not only could the control department not call anyone, even when I called him, there was no response from Chimelong, which was really weird.

The controller in Shangdu felt that there was something wrong, but he didn't pay too much attention to it. Maybe in some areas with very strong electromagnetic interference, the radio communication signal just didn't work. It would be fine if you left that area.

If there is really a communication problem, he should be able to see the special code indicating the unit hangs up.

"Blue Sky 9883, contact Changfeng 134.65." Shang Duzhuang said.

"Changfeng 164.65, Blue Sky 9883." Blue Sky Airlines' crew replied. Suddenly, they added: "The air quality over there is not good today. When we were flying at low altitude, we smelled some peculiar smell in the cabin."

The flight altitude of Blue Sky 9883 this time was not high, only six thousand meters. Compared with the altitude of long-distance cruising, it is indeed not high.
