The two pilots sweated like rain, like falling into an ice cave.

They are pilots who have been trained through a long professional flight course, and they have more than five thousand hours of flight time.

They are not machines, and the long, boring flight will certainly kill them from work, but their judgment and expertise will only steadily increase with the number of hours worked.

The rudder is out of order.

Aircraft automatic flight mode malfunction.

These two failures, which could never happen at the same time, just happened.

"Tower, it's an emergency, our plane is out of order. The other pilot and I would never make a mistake, we were flying in a straight line. ”

The pilot's teeth trembled a little, "I have flown more than ten times to Shanghai Airport, and I can guarantee that there is no city in front of us on our route." ”

"This ......"

The ground tower hesitated: "Although the radar and positioning data displayed on the screen in front of me are exactly the same as the scheduled flight route. ”

"But I'm sure you don't joke about the safety of an airplane. ”

The pilot yelled: "Never, I swear, our plane really lost control." ”

The electronic envoy said solemnly: "You first try to identify the true location of the plane, and I will immediately report this matter to the leader." ”

After saying this, the electronic messenger over there turned his head and smiled at the electrocrystal next to him, "Boss, these two stupid humans have finally found out that they are flying the wrong way. ”

"Indeed, flying for so long to find out that even I was a little surprised. Electrocrystal also smiled, he felt that the two pilots should have discovered the problem a long time ago, at least not long after the change of course to Russia.

The electronic gauges in the cockpit of an airplane can trick their eyes, but the few necessary spare mechanical dials above their heads will not.

If you just look up and carefully calculate the data on the mechanical dial, you can see that something is wrong.

It's a pity~

It's like a person who is used to driving an automatic transmission car, and will be very awkward and reluctant when faced with a manual transmission.

There are too many problems in human beings, and laziness and slackness are the most obvious one.

The electronic messenger didn't even pretend to go to the leader, he cut off the call directly.

The two pilots in the cockpit of the plane did not dare to delay any time.

They force themselves to calm down.

They finally thought of the mechanical gauge above their heads, and calculated that they had been flying in a straight line for almost two hours.

At this moment, the two pilots suddenly realized that the electronic instrument cluster in front of them seemed to be controlled.

Calm down!

The panic would only be a waste of time, and the pilot asked his companion to immediately contact the American aviation command department to report the situation and inquire about their real GPS location, and he himself got up from his seat with a sudden.

He grabbed the flight notebook, quickly flipped to a blank page, and drew a quarter circle on it.

It's true that they're used to relying on electronic meters, but that doesn't mean they only rely on electronic meters.

How did humans navigate before the advent of a wide variety of electronic navigation devices?

Airplanes were invented more than 100 years ago, and night aircraft raids during World War II were the most classic tactical means in warfare. At that time, pilots had to ensure GPS, and they even had to ensure radio silence throughout the mission.

The pilot was keeping his eyes firmly on the porthole, and he had to complete a celestial navigation of the star map through an auxiliary stargazing mirror with sextant parameters.

Using those striking stars or other celestial bodies, using the celestial bodies as reference points, it is possible to determine the true course of the aircraft in the air.

First, find the position of the moon.

The moon is used to locate several other important stars, and the shortest distance from the projection point to the observation point in the coordinates of the auxiliary stargazing mirror is determined by taking the location information of the projection point of the celestial body as the center of the circle.

Use the scale inside to measure the altitude angle of the celestial body, and then use the altitude difference method to solve the intersection of two or three circles......

The pilots made some calculations and were finally shocked to find that they were already over Russian territory at this time. Unconsciously, it penetrated nearly thousands of kilometers deep into Russian territory.

"Can't be contacted!" the co-pilot had cold sweat on his forehead, he had just used all the external communication equipment on the plane, but the headset was full of busy electricity.

"Where's the Huaxia Tower?"

"Also...... I couldn't get in touch, just when the other party said that he wanted to report to the leader. ”

"Calm down. The pilot comforted: "Perhaps the enemy has the ability to eavesdrop on our calls, and after learning that the Huaxia Tower was going to report this matter, they immediately interfered with our communication equipment." ”

"Enemy?" the co-pilot was surprised, "isn't this a malfunction?"

"Failure?" the pilot's teeth kept chattering, and he showed a sneering expression, "The failure of the automatic driving may still be fooled by the failure, but the six monitors in front of us are all showing the Huaxia route, how can this be explained?"

"That Huaxia ground tower, I think there is a high probability that the enemy is also impersonating. ”

"Our plane was obviously in Russian airspace, but they said on the radar screen that our position was near Shanghai. ”

"You mean......" Thinking of a possibility, the co-pilot also became violently trembling, and he pointed his finger downward in a trembling manner.

Below, Russia.

"That's right, who else but the Russians are doing it?"

"How else can we explain that we have been flying on Russian territory for several hours and have not received any warning from the Russian Air Force?"

"Is their radar collectively out of order?"

The two pilots could not imagine what the enemy had used to control the entire plane without their knowledge, and even the electronic instruments were hijacked by them.

But this did not prevent them from confirming that the enemy must be from Russia only by the Russian air defense radar without any reaction.

This is no ordinary commercial flight, and in the cabin is a high-ranking director of the Social Administration, and several representatives of the Ministry of Commerce. If there is any conspiracy in this, it must be directed at Mr. Director.

The two pilots decided to seize control of the plane first, and as long as the control was snatched, they would be able to follow the astronomical navigation and drive the plane to China.

It doesn't matter if the autonomous driving fails, and the fly-by-wire operating system is ineffective.

The two pilots wanted to kiss the designers and thank them for retaining the clunky and inefficient mechanical operation that had existed for hundreds of years.

Although it is only the most basic ascent, descent, and left and right steering, at night, it is a luxury to rely on these functions to land on the runway.

But as long as it reaches China, Russia's electronic hijacking of this plane will inevitably fail.

Starting the mechanical operation is somewhat complicated, and it is necessary to carry out multiple sets of fully manual operation schemes, and even have to disassemble a baffle under the foot and connect the hydraulic pipe of the linkage mechanical tie rod to the rudder.

With their lives threatened, it took the two pilots less than a minute to complete the entire operation.

"Sit tight. The pilot yelled.

The rudder shifts seven degrees to the left, which is the extreme offset angle that the Boeing 747 can achieve at high speeds. Above seven degrees, the plane could roll over or break its wings.

In purely mechanical driving mode, all electronic aids fail. If you change to a novice pilot, it is likely that because of nervousness, or subconsciously thinking that the auxiliary equipment is still working, no matter how much the rudder is offset, the auxiliary equipment will lock at a safe angle, resulting in the destruction of the aircraft.

At seven degrees, the Boeing 747 will shake sharply and the center of gravity will shift rapidly.

Next Second......

Nothing happened in the next second!

The pilot was completely stunned, and his left foot on the rudder was at a loss.

They've switched to mechanical driving mode, why......

Because it is the 21st century, even if there is a pure mechanical control system, it is impossible for this system to be free of any electronic control chips or mechanical auxiliary components.

It is impossible to say that the pilot stepped on the rudder, the rudder drove the lever, and then the tail dozens of meters away from the cockpit also drove the deflection.

At a speed of 800 kilometers per hour, even if the tail is deflected by one degree, the wind resistance pressure it is subjected to cannot be shaken by human power.

Therefore, it needs to be connected to the rudder with a hydraulic pipe, which is then connected to an independent mechanical hydraulic pump, which provides sufficient hydraulic power to drive the tail to deflection.

Even the hydraulic system of a car needs to be controlled by electronic chips, not to mention an aircraft that is more than ten times more complicated?

The only difference is that the hydraulics on the plane have backup electronic chips, and there is a backup of one burned out. Now the two chips, as well as the hydraulic pump, have been disconnected from power by the electrocrystal.

The two pilots also realized that there was a problem in one link, and they wanted to notify the pilot to go for maintenance.

They shouted into the headsets for a long time before they realized that not only were external communications disrupted, but even the plane's internal communication system was completely attacked.

Without saying a word, the co-pilot stood up and pulled the passage hatch, and then ......

Belch......

The hatch is locked, and a red plaque that says "stopsuddenly" appears on the doorguard.

Since the 2001 crash into the World Trade Center, all airliners have replaced the isolation door that connects the cockpit to the outside world, replaced it with bulletproof materials, and added a locking function. In the event of an emergency, the pilot has the right to lock the isolation door from the inside without notifying the crew.

Once the message "stopsuddenly" appears on the door, outsiders can no longer open the door, not even the pilot.

This is to prevent someone in the cabin from threatening the pilot with a crew or passengers, after all, the human heart is full of uncertainty.

Only after the plane has landed, the ground technician with special equipment can open the maintenance window from below.

"Is it ......?"

"Among those passengers, are there Russian agents?" the pilot thought of a terrifying possibility.

Someone should be inside and out.

With this conjecture, he immediately thought of the reporters who carried a lot of reporting equipment.

If someone has special electronic equipment in it, the security check may not be able to check it out.

With this conjecture, the two pilots did not dare to rashly slam the door to attract the attention of the outside crew members. The enemy can control even six information displays, which makes it theoretically easier to control the surveillance screen.

It seems to be a peaceful cabin surveillance screen, who knows what the situation is now?

The two pilots hurriedly dug through the aircraft equipment maintenance manual, trying to find a solution in the cockpit to regain control.

But!

At the moment when they just opened the manual, the Boeing 747, which had been flying smoothly, suddenly sank.

Faintly, the two pilots could still hear the sound of the announcement coming in from outside the hatch.

"Dear Mr. Director, and all media representatives, the destination of our flight, Shanghai International Airport, is about to arrive. Please fasten your seatbelts......"

The co-pilot was pale, his teeth were shutting like a woodpecker, "This...... This, who is this...... Talking?"
