In the cabin of Flight 9811, with a loud bang, Xu Cang felt that there seemed to be thousands of pointed needles stirring in his head on both sides, and Xu Cang was sweating profusely.

Since Xu Cang happened to be directly above the pressure relief port, the air pressure changes the most violently, and the physiological reactions it bears are naturally the most serious. Even with Xu Cang's willpower, it is difficult to withstand such pain.

However, Xu Cang did not lose consciousness from beginning to end. He grabbed Xia Shuyue next to him with his left hand: "Open your mouth!"

Now is the most severe moment of pressure change. We must ensure the balance between inside and outside the body as much as possible, otherwise the body will feel very uncomfortable.

Many people feel uncomfortable at the rate of rise during takeoff, not to mention that the current situation is equivalent to instantly changing a person from an air pressure altitude of 8,000 feet to a height of 30,000 feet. How can this human body withstand it?

Xia Shuyue's reaction seemed to be lighter than Xu Cang. She even held Xu Cang's left hand with her backwards: "Brother, I'm fine!"

Xu Cang immediately raised his hand and signaled Xia Shuyue not to speak anymore. At this height, oxygen is extremely scarce.

"Damn it, why haven't the oxygen mask fallen off yet?"

Just as Xia Shuyue's voice fell, the oxygen mask in the cabin fell automatically. The oxygen system in the cabin can be artificially overloaded by the cockpit, and it will automatically start after the cockpit height exceeds a certain value. However, in some extremes

In the case, the oxygen mask in the cockpit does not fall automatically, which requires the cockpit to artificially open the passenger oxygen electric gate.

Therefore, when dealing with the pressure relief of the cabin, even if the cabin oxygen mask has automatically fallen down, the crew members will still manually open the passenger oxygen valve to ensure that all oxygen masks can fall off.

As soon as the oxygen mask fell off, Xu Cang quickly put the oxygen mask on and felt the fresh air flow blowing out of the oxygen mask. Xu Cang's mind became clearer. But the strap of the oxygen mask was tied to his face, making him feel very good.

It feels uncomfortable because his skin on his body is now like tens of millions of needles when he touches it. I don’t know why it is like this.

This is the first time Xu Cang used a passenger oxygen mask as a passenger.

After doing my own things, Xu Cang quickly went to check Xia Shuyue's next to me. I can only say that Xu Cang was worried too much. Xia Shuyue was a flight attendant. During the training, he simulated wearing an oxygen mask that passed the cabin. Xia Shuyue even

More skilled than Xu Cang.

"Brother, I'm fine." Xia Shuyue curled up subconsciously. Due to the damage to the fuselage, the cold air outside the altitude began to affect the cabin. The personnel in the cabin not only had to withstand the discomfort caused by lack of oxygen and pressure difference.

It will also usher in a low temperature below minus twenty degrees Celsius.

Xia Shuyue's right hand couldn't help but hold Xu Cang's arm, as if this would make her feel a little safe. The roar of the wind echoed in her ears was like the roar of death, and the increasingly violent vibration of the fuselage was like a giant beast that was about to be fragile.

The plane can be mastered and can be crushed at any time.

Xu Cang's hands were very cold, as cold as ice, even colder than the air floating around the 30,000 feet high.

Suddenly, a wet drip on the back of Xia Shuyue's hand. She was slightly stunned. When she looked closely, she found a drop of dazzling blood. When she looked up, blood was constantly flowing out of Xu Cang's left ear.

Perhaps it is because the temperature in the cabin is too low now, and the blood flowing out seems extremely sticky.

"Brother, your ears!" Xia Shuyue exclaimed. However, she soon noticed that Xu Cang's attention had never been placed in his bleeding ears. His eyes were staring in the aisle, staring at him tightly.

The front curtain is used to isolate first class and economy class.

"Why is it still rising, why is it still rising!" Xu Cang gritted his teeth, and a trace of blood oozed out of the corners of his mouth. Xu Cang now felt that his flesh had separated, which was a sign of boiling body fluids.

As we all know, the boiling point of water is directly related to air pressure. The lower the air pressure, the lower the boiling point of water, and vice versa. The air pressure is also related to the height, and at high altitude, the air pressure will also decrease.

This means that at higher altitudes, the lower the boiling point of water will be.

That is, there is an extreme situation, that is, at a certain height, such as a place more than 19 kilometers away from the ground, the boiling point of water drops to the normal body temperature. In this case, the body fluids in the human body will be like

The boiling water boils like a boiling water. It is like blowing a balloon, and the human body will experience uncontrollable swelling and eventually die.

Of course, the altitude of 30,000 feet is less than 19 kilometers, but Xu Cang already felt very uncomfortable. This type of physiological reaction has certain individual differences, such as Xu Cang's overall physical fitness must be excellent

In the summer, the discomfort of the summer is obviously smaller than that of Xu Cang.

The symptoms of boiling body fluids start from the mucosa, such as the nasal mucosa, oral mucosa, etc. Just now, due to the rapid changes in air pressure, the eardrum, which is rich in capillaries, began to bleed, and the bleeding at the corners of his mouth is also the reason. Moreover, as the

With increasing height, the bleeding problem will become more and more serious.

Xu Cang could feel that the plane not only did not descend, but was even climbing slowly. This was simply the most ridiculous thing in the world. What are you doing to climb up? Are you looking for death?

Xu Cang turned his body and opened the blindfold and looked out. It was clear that the sky was clear, but it didn't seem that it could not fall due to weather reasons.

"What the hell are you doing?"

The surroundings were full of passengers' panic and fearful screams. Many people still don't know how to wear an oxygen mask even when the flight attendant had already taught him how to wear an oxygen mask before taking off.

At high altitude, I had difficulty breathing and couldn't wear an oxygen mask, so I was naturally anxious and afraid. I could even hear crying in the cabin.

The messy voice filled Xu Cang's ears, making Xu Cang, who was already worried, even more irritable.

Perhaps the shouting nearby was too tragic, Xia Shuyue asked timidly: "Brother, will I go and help them?"

However, just as Xia Shuyue said, Xu Cang shouted coldly: "No!"

Xu Cang also wants to help others, but he does not have a portable oxygen cylinder. The oxygen mask in the cockpit is connected to the roof, which limits the range of movement of people. At most, a group of people in the next seat can help others to go to

If you help a little further away, you must take off your oxygen mask.

At today's height, just half a minute or half a minute is enough to make an adult lose consciousness. Xu Cang didn't want to rescue himself, but instead became the target of others' rescue.

Moreover, the biggest and most fatal problem now is not the oxygen mask, but the plane!

As long as the plane can descend quickly, many things can be solved. If the plane continues to climb, the entire plane will be dead. You must know that the oxygen in the cabin is not as long as the oxygen in the cockpit, which is only ten minutes. If it encounters it,

The oxygen generator is old, and it is a big deal to say whether it can last enough time.

The situation of the plane is very delicate now. From the vibration of the fuselage and the whistling of the airflow, it is almost certain that the fuselage is damaged. Xu Cang strongly suspects that it is the problem on the other side of the cabin door.

In the case of damage to the body, in order to ensure that the body structure does not exceed the limit, the speed needs to be controlled during emergency descent, that is, maintaining it at a relatively low speed.

In this way, at relatively low speeds, the aircraft cannot maintain a satisfactory descent rate. This means that even if the aircraft starts to descent from now on, it will take more time than the normal emergency descent, let alone this

When the plane is still rising, it also consumes the precious oxygen stock in the cabin.

As time goes by, the chaos in the cabin has begun to evolve into a cry for help. The despair brought by suffocation shows the madness of people to the fullest. Some people who can't wear oxygen masks even cannot even think that even if they don't wear oxygen masks tightly.

, you can also press it on the face. Although the oxygen is leaked, it still has some effect.

There is no way. Many people cannot think rationally when they are afraid.

After waiting for more than ten seconds, the plane's rising posture still did not change at all. Xu Cang looked at the increasingly chaotic cabin and his mood could no longer calm down. The environment could affect people, and Xu Cang could not do that without

The colored green lotus, and he didn't want to put all his hopes in the cockpit in front.

It's been long enough, he has been waiting for a long enough time. Even if the crew members in the cockpit react slowly and the program execution is a bit slow, they will start to make an emergency decline at any time. If it weren't for some, Xu Cang would have predicted

An unexpected strange problem is that there is a problem with the crew in the cockpit!

Someone has an accident!

Suddenly, Xu Cang's heart thumped wildly and he thought of a very bad possibility. If his body reacted so obviously, then if you reasonably infer, why would the pilot in the cockpit not have the same or even more serious body?

What about the reaction?

But if it is just a physiological reaction, it will not be completely disabled. That is to say, the body of the flight crew has an unexpectedly dangerous situation. Then, it is worth thinking about whether there is still a single one in the cockpit now.

Are people who are conscious enough to control the plane?

Or, the plane is now unmanned.

When Xu Cang thought of this possibility, he was shocked. This was not impossible, but extremely possible. As long as he was a pilot, if he had a little consciousness, he would never let a plane that relieves pressure continue to rise.

of.

"No! You can't stay here anymore." Xu Cang was not a style of waiting for death. Thinking of the possibility that both people in the cockpit are now disabled, this idea spread uncontrollably as soon as it appeared and could not be eliminated.

His brain kept turning, and suddenly he began to untire his seat belt. When Xia Shuyue next to him saw Xu Cang being untied, she immediately grabbed Xu Cang's hand: "Brother, what are you going to do? Didn't you just now?

I'm going to leave."

Xu Cang grabbed Xia Shuyue's hand with his back hand. He lowered his body and leaned close to Xia Shuyue, deliberately pressing his voice: "Shuyue, listen well. I suspect that the person in the cockpit in front is no longer able to do it, and the plane is still there.

Keep going up, if we continue like this, we don’t want to live, so I have to go ahead.”

Xu Cang whispered so quietly, for fear that people around him would hear it. If the people around him heard that the people in the cockpit were disabled, wouldn’t the already chaotic cabin be overturned?

"How could this happen?" Xia Shuyue recovered quickly after a brief shock. After experiencing the 9211 incident, Xia Shuyue's psychological quality is indeed very comparable. However, this does not mean that Xia Shuyue agreed.

Xu Cang's approach was still quite worried: "But, why did you go there? You can't breathe at all without an oxygen mask. Moreover, the cockpit is locked. Even if there is a problem inside, how can you get in?

You know the door, and the bomb may not be able to blow up."

It can be seen that Xu Cang was also quite nervous. His decision below would undoubtedly bring him great danger, but he had to try it.

"If I remember correctly, there should be emergency supplies on the front luggage rack in the first class cabin, and there should be portable oxygen cylinders inside. With the portable oxygen cylinder, I can move freely. As for the cockpit door." Xu

Cang's eyes flashed with brilliance: "The security officer knew the password of the cockpit door, and I can convince him to let the security officer open the cabin door!"

The cockpit door can also be opened with a password, but only the captain and aviation safety officer on the entire plane know it, and the company will change the cockpit password every once in a while to ensure absolute safety.

"You can open the cockpit by password and only if the cabin door is accidentally locked. It is a violation of safety rules for opening the door to you, and he will not open it for you." As a flight attendant, Xia Shuyue also knows the cockpit.

entry and exit regulations.

As the only guarantee for the cockpit, the cockpit door is absolutely not allowed to be opened at will. If it is to be opened, strict steps and procedures are required.

There are extremely strict restrictions on opening the cockpit door by the aviation safety officer. It is impossible for Xu Cang to agree to open it alone. Once something goes wrong, the aviation safety officer will bear unimaginable punishment.

If this plane belongs to Blue Sky Airlines, there may be a little chance. But the problem is that the plane and the crew members on the plane are all from Muhua Airlines, and they don’t have many people to Blue Sky Airlines.

If there is a deep bond, then this last possibility will be eliminated.

Of course, Xu Cang knew it was difficult to convince the aviation safety officer, but he had to give it a try.
