Chen Mo glanced at the position in front of the captain, which was where the plane's air conditioner was located.

According to what Jarvis learned from the ATA system, the plane had reported a problem with the air conditioning system shortly after takeoff, but then lost contact with the ground.

Presumably, the captain fainted when he was checking the air conditioner in the past.

However, I am afraid that things will not be so simple, just the failure of the air conditioning system will never make the entire plane more than 100 people unconscious.

And Chen Mo's abnormality when he opened the cabin door before, as well as the situation of everyone in the cabin, also made him have a certain guess.

Immediately, Chen Mo directly asked Jarvis to connect to the plane's system and check the flight log.

Outside the plane at this time, two F15 fighters were flying on both sides of the passenger plane, one left and one right, through the glass of the cockpit, the two pilots saw Chen Mo who pushed open the hatch and entered the cockpit, and they immediately hurriedly reported to the command center.

"Iron Man just got into the cab! He's trying to find a way to save the plane! ”

The command center was silent for a moment, and then immediately ordered.

"Find a way to contact him, and we can guide him to eliminate the danger!"

At this time, they don't care about pursuing the problem of this Iron Man who appeared out of thin air, and now saving people is the most important thing!

The two pilots immediately sent a communication to the airliner via a public channel.

It's just that after their words came out, even they themselves felt a little awkward.

"Iron Man in the passenger plane, we are the United States Air Force, please reply when you receive it, we can guide you to eliminate the danger!"

Chen Mo also heard the sound of the passenger plane's communicator, but he didn't pay attention to it.

Although he can't fly a plane, he doesn't need to be guided by others, and this problem is just a small scene for him!

It was much easier for him to deal with it himself than to listen to a group of so-called insiders.

Soon, Jarvis showed the anomaly analyzed in front of Chen Mo's eyes.

From the moment of takeoff, the temperature and pressure in the cabin began to drop and soon exceeded the safe values, while the pressurization device, which was supposed to run automatically, was never activated!

This should be the reason why this plane turned into a ghost flight!

The plane itself flies at an altitude of 10,000 meters, the air pressure here is only 0.3 atmospheres, the oxygen content is only 30 percent of the ground, and the temperature is as low as minus 35 degrees.

In order to avoid the "altitude sickness" in the environment of low pressure and lack of oxygen at high altitude, a pressurization system is installed inside the aircraft, so that the aircraft has been flying under heating and pressurization.

However, considering factors such as cost, cabin wall endurance, and human adaptability to air pressure, the cabin usually does not add a standard atmosphere, but about 0.6 atmospheres.

During take-off and landing, the cabin pressure drops from 1 atmosphere before take-off to 0.6 atmospheres during cruising, and then slowly increases to 1 atmosphere during landing.

It is estimated that it is precisely for this reason that the reduction in air pressure did not arouse the captain's vigilance at first, but thought that the air conditioning system was faulty and did not heat up normally, so he would get up and go to the back to check.

But before he could realize that something was wrong, as the flight altitude climbed rapidly, the pressure in the cabin quickly decreased, and the oxygen in the cabin quickly became very thin, and the two pilots passed out in a short time.

Many of the passengers in the cabin behind had fallen into a coma due to lack of oxygen before the oxygen mask popped out, and although others wore masks, the oxygen in the oxygen mask could only last for 12 minutes, which was originally used for a short time in the case of high-altitude loss of pressure, until the plane descended to the high oxygen content airspace.

However, because the pilot and co-pilot were already unconscious at that time, the plane did not descend but continued to climb, and when the oxygen in the oxygen mask ran out, everyone lost consciousness due to lack of oxygen and fell into a coma.

But not everyone passed out!

Just when Chen Mo found the cause of the plane accident and didn't have time to make a move, a somewhat messy footsteps suddenly sounded in the cabin behind him.

Chen Mo couldn't help but turn his head to look, but saw a sturdy figure wearing a male flight attendant's uniform holding on to the seats on both sides of the passage, staggering towards the cockpit.

Chen Mo found that he was holding a small oxygen cylinder in his hand, which should be an emergency backup oxygen cylinder on the plane, he could barely stay awake even when everyone on the plane was unconscious, obviously thanks to this oxygen bottle.

However, Rao is like this, which is enough to surprise Chen Mo, after all, many people in the cabin didn't even react, and fell into a coma unconsciously, and the rest also lost consciousness after the oxygen in the oxygen mask was exhausted, but he was able to hold on to find a spare oxygen cylinder, and it was not easy to persist until now.

And at the same time that the male flight attendant appeared, his information also appeared on the holographic screen in front of Chen Mo's eyes, and after reading it, Chen Mo couldn't help but understand it in his heart.

This flight attendant named Gao Yuan used to be a diver and served in the special forces, and his physical fitness, especially for the anoxic environment, is much stronger than ordinary people, and his sensitivity and vigilance are also higher, so he can stay awake when he is deprived of oxygen in the early stage, and when he realized that the oxygen in the oxygen mask was about to run out, he did not sit still, but took the initiative to abandon the oxygen mask and found a spare oxygen cylinder in the oxygen thin cabin.

However, Chen Mo was not optimistic about whether he could save the plane.

First of all, flying a large airliner is a very specialized job, and the male flight attendant, although he is from the special forces, obviously does not have this skill.

The two captains and co-pilots have fallen into a deep coma at this time, and even if they are now put on oxygen masks, it can only reduce the risk of their death from lack of oxygen, and it is almost impossible to make them wake up, or even fly the plane again.

Moreover, looking at the performance of the male flight attendant, the oxygen that the spare oxygen cylinder can supply is obviously very limited, which can only make him barely awake, and it is very difficult for him to move, if there is no Chen Mo, he may not even be able to open the cockpit door, and can only fall into a coma like everyone else after the oxygen in the spare oxygen cylinder is exhausted.

He was obviously aware of this, so when he finally struggled to get to him, and found the hatch open, he couldn't help but have a look of surprise on his face.
