The Boeing plane's route is slowly heading north.

However, all the electronic instruments in the cockpit "faithfully" told the two pilots that they were flying in the direction of Huaxia.

"Flight E7004 Hear Listen to Answer......"

"Number E7004 received. The pilot lazily answered.

"You are about to enter the airspace of China, and I am the aviation liaison officer who will contact you this time......

The electronic messenger who had just finished imitating the Japanese ground tower began to imitate the Huaxia tower again, and repeated the call of the liaison officer of the original tower before.

After a while, the pilot thought that he had established contact with the Huaxia Tower, and told the news of entering Huaxia airspace to Mr. Director through the radio.

The plane is still in autopilot mode.

The dark night sky obscured their field of vision, and if they had the ability to see at night, they would suddenly find that around their plane, there were five small aircraft and an astonishing "alien" flying machine.

Electrocrystals have quietly reduced the speed of the Boeing to 800 kilometers per hour, which is the maximum speed of the Nighthawk aircraft.

The Lord battleship flew at a height of 100 meters below, at an angle of 30 degrees to the Boeing aircraft.

A Nighthawk aircraft equipped with a small anti-aircraft radar flies ahead, at which point the radar is turned on, firmly locking onto the Boeing aircraft.

On the radar screen, the silhouette of the Boeing plane, which was originally clearly visible, actually disappeared from the fuselage part, leaving only two wings.

The image was transmitted to the electrocrystal, and the electrocrystalline began to adjust the angle of the Nighthawk aircraft to minimize the radar reflection of the Boeing aircraft.

There is often more than one surface-to-air radar, especially in coastal areas, where there are not only civil aviation radars, but also military radars that are not located.

Fortunately, the electrocrystalline can calculate the approximate orientation of the radar through the working parameters of the sound-absorbing steel stealth material on the surface of the lord battleship when irradiated by electromagnetic waves, and adjust the flight angle at any time.

Whether it's a satellite signal, a radio signal, or a radar detection signal.

They are both a manifestation of electromagnetic waves, differing only in frequency and power.

When energized, the sound-absorbing steel can swallow up any electromagnetic waves that shine on its surface. Then the electrocrystalline only needs to pass through a number of peak detectors connected to the sound-absorbing steel to determine which angle and which direction the electromagnetic wave is the most intense.

Radar signal transmitters are high-power radio transmitting devices. Most of the world's anti-aircraft radars operate at frequencies between 5~15 GHz.

Radio electromagnetic waves and satellite signals, both below 1 GHz.

With this data, it becomes very easy to locate the approximate location of the radar.

The electrocrystal is also sure to make this Boeing 747 completely invisible.

……

In the face of overwhelming science and technology, the anti-aircraft radar on Qizhou Island is even more powerless than a bat with its ears blocked.

A lord warship, five Nighthawks, and a Boeing 747, in a dense zigzag formation, roared past it at an altitude of 9,000 meters.

Half an hour later, the flight formation crossed the territorial waters of South Korea.

In the cockpit of the Boeing plane, the lazy pilot who was lying in the business seat returned to his seat.

Because according to the voyage and time, in another twenty minutes they will fly to Shanghai and can enter the landing procedure.

The pilot put on a headset and said, "Flight No. E7004 calls the tower." ”

"The tower received, please speak. ”

"We are about to arrive in Shanghai, please send us the real-time weather data over the pre-landing airport. ”

The electronic messenger answered, then tapped on the keyboard, and casually sent a copy of the weather information that barely matched the landing situation.

"Number E7004, you are expected to enter the landing procedure in twenty minutes, now please check the condition of the aircraft. ”

"Understood!" the two pilots sat up straight and began to check the data on the electronic instruments.

It's nighttime, and landing an aircraft at night needs to be accompanied by a lot of instrumentation data. In addition, the real-time updated airport weather data shows that the wind speed over Shanghai International Airport is 7 knots. At this wind speed, if the huge 747 wants to land, it can only choose the runway with the positive and negative winds.

Shanghai International Airport has four runways, and in theory, no matter which direction the wind blows, the plane can find a suitable runway for its own landing.

But now it's night, and in the cabin there are Mr. Director and a group of reporters, and the two pilots have to make sure that the plane lands very smoothly.

"Altimeter is normal. ”

"The auto-trim system is working. ”

"The light-assisted landing system is working. ”

"Control system ...... normal"

After confirming that the landing system of the aircraft was fine, the two pilots reported to the tower liaison officer that the plane was in normal condition and met the landing standards.

The tower liaison officer was suddenly startled and shouted: "Wait~"

"What...... What's the matter?" the two pilots were frightened.

"There are emergencies. ”

Several of the electronic emissaries in the lord's warship began to exchange heads and ears, and some Chinese terms that they did not understand kept popping out of their mouths, creating an atmosphere of chaotic communication.

After about ten seconds, the electronic messenger in charge of communicating with them put on the headset and said urgently: "A Boeing 737 plane that was about to take off just now had an abnormal lock in its wheels. ”

"Now the captain of that plane has carried out the engine emergency shutdown procedure. ”

"Now that runway 2 where you are going to land has been temporarily shut down, the ground crew has to urgently troubleshoot and tow the plane off the runway. ”

"You go into circling mode first, wait for the ground crew to complete the emergency repairs and then correct the route. ”

As soon as the news came out, the two pilots of the Boeing 747 immediately scolded their mother.

What is this called?

They very much wanted to greet the ground staff at Shanghai Airport and the two pilots who were paralyzed on the runway.

Abnormal lock of the wheels?

If this ridiculous fault is on them, they will have to take off their uniforms, okay?

"We're a special plane, you know who's in the cabin, and we have priority landing. The pilot slapped the dashboard and shouted, "No matter what, you have to find a way to tow the plane off the runway." ”

The emissary shrugged his shoulders, "I'm sorry this isn't a situation I can control, now that the airspace over the airport is saturated, you guys are circling over the sea." ”

"I applied for an airspace at an altitude of 9,000 meters, and you can hover for a maximum of fifteen minutes. ”

The two pilots turned off their headsets, and there was another crackling greeting.

It takes at least two minutes for the plane to circle in a circle.

Due to unexpected circumstances, it is not uncommon to have to hover over the airport and wait for landing, where the airspace is so tight that planes can usually only enter and hover for two minutes. In this process, it is obvious that the attitude of the aircraft will be offset, and the inertia will change left and right.

This feeling will of course be uncomfortable for passengers, and commercial airlines don't take passenger feelings into account, and they certainly can't.

Fortunately, the liaison gave them a fifteen-minute circling distance.

If the hovering time exceeds 12 minutes, the passenger will not be aware of the change in inertial offset.

The tower is the boss, and the two pilots can only reluctantly enter the hovering mode.

Switch out of autopilot, reroute the flight, and then enter autopilot mode again.

The two pilots noticed that the plane was beginning to deflect to the left, and then continued to complain.

Unbeknownst to them, this course change was the last time the Electrocrystals adjusted their flight path and began to fly towards their final destination.

By this time, the Boeing 747 was already flying along the territorial waters of Russia.

Two thousand kilometers from the final destination, which is called Yamsk.

It is one of Russia's only two ballistic missile test sites left since the collapse of the Soviet Union.

In addition, Dianjing also inquired from several international news websites to find rumors that do not guarantee the authenticity. It is rumored that the Yamsk missile test base is likely to test-fire a new ballistic missile in the near future.

Two thousand kilometers, two and a half hours of flight.

That is, the time to circle twelve times.

……

What they thought was the end of the first lap of the circle, the pilot complainingly asked the tower, what is the situation at runway 2 now?

"The situation is a bit complicated, the ground crew has just checked the wheels and found that it was a system failure that caused the wheels to lock up automatically, and they may have to contact the Boeing technicians. ”

Wheel lock-up, which means that the tractor cannot take the aircraft off the runway and must be unlocked.

On the second lap, the pilot continued to complain and asked if it was possible to land on the other three runways.

The tower liaison said that the wind over the airport has strengthened a bit, and the crosswind has a serious impact. The Boeing 747 is a large aircraft with weaker resistance to crosswinds, and currently only runway 2 is qualified.

In the third and fourth circles, the tower liaison said that Boeing's technicians in Shanghai had arrived and believed that the problem would be solved soon.

The pilot said: "Do you think that our plane has just been refueled from the New Thousand Islands Airport, and the remaining fuel of the plane can fly for three hours." That's why you deliberately let us hover and wait for landing?"

"How so, sir?" the e-messenger reassured, "Once the runway opens, I guarantee you are the first flight to land." ”

Lap 5......

The co-pilot looked out of the porthole boredly.

It was pitch black outside the porthole, and occasionally a cluster of lights could be seen drifting slowly in the deepest part of the night.

It was a freighter sailing at sea.

In the sixth lap, the director of the bureau, who was resting in the first class cabin, asked the flight attendant to ask the pilot why the plane had not landed.

After explaining the reason, Director Nenan Bohn was slightly dissatisfied, but he didn't continue to say anything.

Just when the pilot was communicating with the ground tower, mixed with thick fire, the co-pilot suddenly sighed, "I just seem to have seen land." ”

"Land?" the pilot turned his head sideways to look out of the porthole, "I can't see anything." ”

"I can't be 100% sure, but it really looks like there's a small town light flashing. ”

The pilot, who was already in a bad mood, immediately frowned.

There is no reason to see a village on land.

The aircraft automatically circles over the sea, and even if there is no human operation, the autopilot mode can ensure that the path of the aircraft is consistent every time it circles.

Autopilot, only flying more steadily than the pilot, the route is more precise.

But whether it is inertial navigation or GPS positioning map, there is no shadow of land.

"Twelve minutes later we'll pass over the position again, and we'll observe together. ”

The co-pilot nodded.

Twelve minutes passed quickly, and the two pilots looked down intently.

It was still pitch black below, and there was no shadow of the town's lights.

The co-pilot muttered, "Maybe it's a mistake......"

"You...... That's right. The pilot was stunned, and he pointed to the end of his vision. There, there was a faint orange-yellow dot of light.

It was not the light that any giant ship could emit, and the pilot with excellent eyesight could accurately judge that the point of light was clearly the light emitted by a city.

At this time, the Boeing 747 aircraft was heading towards that point of light.

With a fixed reference, the two pilots realized to their horror that the plane was now flying out of a straight course!

"Switch to manual driving right away. The pilot roared, and immediately reported to the ground tower, "Tower tower, please upload the radar path map of our aircraft immediately." ”

"You ...... What do you want a radar path map for?" said something strange in the voice of the tower liaison officer.

The pilot yelled: "There is a problem with our autopilot mode, the plane is now flying in a straight line. ”

"No!" the tower liaison said in a confused tone, "the radar map shows that you've been circling. ”

"Also, the GPS map is fine, could you be mistaken?"

"It can't be. ”

The pilot began to deflect the rudder, but the rudder shifted fifteen degrees to the right, but the direction of the plane did not move at all.

"This ......"

The two pilots glanced at each other, and then sweat rained down like a cave in ice.
