Chapter 1434

“…… The communication module has been physically removed, and the hijackers seem to have no intention of dialogue at the beginning. They have been completely removed, even the standby communication system has been unplugged. And remote control module and automatic driving system... Damn it! "

Squatting in front of the console was a man with a short head and glasses.

His name is fan Sheng. He is an engineer of an aerospace enterprise in Pan Asia.

About a week ago, he went to Tiangong city for an academic conference, but he didn't expect to encounter such a thing on his way home.

But thanks to his presence here, otherwise the bionic man that AI sent to pick him up has been scrapped in the previous battle. I really don't know what to do with the boat.

Looking at fan Sheng, who was sweating, Lu Zhou frowned and asked.

"Can it be repaired?"

"It's impossible to repair it. They didn't even think about how to install these things in the way of violent demolition," said fan Sheng, with a wry smile on his face, raising his arm and wiping his sweat. "Fortunately, they didn't understand the transport ship well enough. I changed the settings of the transmitter on the facility maintenance system to developer mode. Although the channel is a little narrow, if it's just an audio call, it should be OK. "

"Can I use it now?" the boat said at once

"Already I have received a strange communication request here. It should be the Pan Asian fleet that has noticed the abnormality on our side. "

Lu Zhou: "connect them now!"

Fan Sheng quickly nodded his head, and made a few quick taps on the holographic panel with ten fingers.

"OK It's done! "

The light and shadow on the holographic panel changed, and a video call window was soon presented in front of Lu Zhou and fan Sheng.

Although the location of the video window is a snowflake white, we can't see the person standing at the end of the video, but the repeated voice from there can be heard clearly.

“…… This is Pan Asian first fleet, flight n-177. Can you hear me

"If we can hear you, we hope to have a dialogue with you. Whatever you ask, the door of dialogue and peace will always be open..."

Take a deep breath, said the boat.

"This is flight n-177 I'm a passenger on the flight. We've taken control of the flight from the hijackers. "

The opposite side was silent for a while, as if surprised at the news.

The boat waited for two seconds quietly, and a response came from the other end of the communication channel.

Pilot: "can you slow down?"

"Yes We have shut down the main engine, but the automatic navigation module has been removed by the hijackers, and two captains have been executed by the hijackers. "Looking at the channel data displayed on the navigator, the boat said with a headache on its face," you'd better send someone to help us Those hijackers can board this transport ship, you should have a way, right

This time the communication channel was silent for a long time.

Pilot: " Flight n-177, I hope you can keep calm when you hear this news. "

From that heavy tone, the boat had guessed something vaguely, and the mood could not help sinking to the bottom.

Looking at fan Sheng, he was silent for a while and said.

"Tell me."

Pilot: "37 minutes ago, you missed the final deceleration window."

Lu Zhou: "that is to say, we can't come back?"

Pilot: "yes..."

Lu Zhou didn't answer immediately, but took a look at fan Sheng.

"Is that so?"

Fan Sheng's face was pale, his lips trembled and he nodded softly.

“…… There is such a saying. But not really? Should be able to save it! What about your landing craft? At least give us some supplies... "

"The dolphin 230 transport ship has 12 pairs of k-15 electric main engines. In terms of longitudinal acceleration, even if the sentinel level patrol ship of the first Pan Asian fleet starts from the nearest space port without considering the return voyage, it is difficult to achieve the same speed as you in 72 hours. And the rescue window period is only 11 hours. Once you and the Earth Moon system pass by, it will take two weeks at the fastest time, so our air carrier and your flight can complete docking on the orbit 37 million kilometers away from the Earth Moon system. "

Looking at fan Sheng, Lu Zhou continued to ask, "is what he said true?"

Fan Sheng nodded pale.

"The dolphin civil transport ship was designed to facilitate passengers to and from the Earth Moon system and Mars system, so 12 pairs of main engines were installed at the tail If it's just a race, a military transport ship with ammunition and endurance supplies doesn't have to catch up. "

"I'm afraid the air thieves have been preparing for ambush since a week ago..."Just as fan Sheng explained the reason to the ship, Yang Wu stepped forward to pat the navigator on the shoulder in the headquarters of the first Pan Asian fleet, looking at a snow white video window.

"Let me talk to them."

The navigator took a look at the commander and nodded after seeing him, so he gave up his position.

Yang Wu stared at the snow white holographic video window and said in a serious and steady voice.

"This is the headquarters of the first Pan Asian fleet. I'm Yang Wu, military operations consultant."

"I'm sorry to inform you of this, but the possibility of your safe return is very small. Even in the best of circumstances, it will take two weeks for our rescuers to arrive. So we need you to take some necessary self-help measures to avoid the worst. "

“…… If you can control this flight, I hope you can turn on the left steering engine, change the current channel, and avoid direct collision with the space station Tianzhou. "

Lu Zhou: "how many degrees to the left?"

Yang Wu: "if you are not sure, keep the left steering engine running at full power for more than 720 seconds."

720 seconds

Full power turns 720 seconds, which is to avoid the earth directly and plunge into the unmanned deep air.

Lu Zhou: "do you mean to let us give up?"

Yang Wu said in a serious voice: "we have never given up on you, and never meant to let you give up. Just for the safety of Tianzhou and tens of thousands of people on the space station, I hope you can keep enough safe distance from it. We will try our best to rescue you, but we also hope you think about the overall situation. "

"What do you call it?"

"Yang Wu."

"Comrade Yang Wu," gazing at a snowflake in the holographic window, the tone of the land boat gradually sank, "there are more than 200 passengers on the ship, most of them are my compatriots, as well as people from other countries and organizations around the world. I agree with your view that the overall situation is important, but things are far from that. As long as I'm here and I'm alive, I won't allow them to die for nothing. "

Yang Wu: "can you fly a transport ship? What do you want to do? "

The boat smiled faintly.

"The principle is almost the same, but the difference is that the operation becomes more cumbersome. The essence of spaceflight is a mathematical problem, and as long as it is a mathematical problem, there is a solution. "

Yang Wu squinted, stared at a snowflake white holographic screen, and said in a deep voice.

"Who are you?"

"It doesn't matter who I am. I just need your cooperation."

The communication was cut off.

Flight n-177 seems to have made up its mind to gamble on the fate of itself and the Tianzhou, and continue on its way along the established channel.

The command room of the first Pan Asian fleet is surrounded by tense emotions.

Everyone's nerves were stretched to the limit, staring at the flashing green dot on the radar.

"The channel hasn't changed. Flight n-177 is heading for Tianzhou!"

"Collision expected in 11 hours!"

"Aim at them. We can't risk tens of thousands of people on the Tianzhou!"

"They have no chance of surviving If there are any, even 1% - "

" not at all, "said the space technology consultant, looking at the arguer's consulting team, who had not spoken all the time," although the possibility may be smaller than 1%... "

The commander looked at him at once, "what do you say?"

"The catapult effect," continued the space technology consultant, looking at the commander, "although according to the current channel, their remaining fuel can no longer be returned by normal means, if the catapult effect is used, it is not necessarily not."

The army adviser frowned and asked.

"Slingshot effect? Do I remember that was used to speed up the drone? "

"It's not necessarily acceleration. When the planet moves to the right in the horizontal plane, if the aircraft flies over the planet from the left side of the planet at a proper angle, it will be impacted by the right impulse of the planet. In theory, if they skim the earth from a synchronous orbit, they can use the slingshot effect to extend the rescue window as long as the angle of penetration is appropriate. "

Commander: "how long can it be extended?"

"I can't say, shouldn't this kind of thing ask the computer?"

The commander immediately looked at the staff at the front desk and ordered.

"To launch the AI battlefield analysis system, I need to know the success rate of the plan and the possible risks."

The progress bar on the holographic screen flickers slightly.

Soon, the results of the evaluation appeared in front of everyone.

And this result, also let the expression on all faces all coagulate.

"Success rate 2% The probability of collision between the flyby synchronous orbit and the Tianzhou space station is 75% Damn it, it's still under the assumption that there are experienced pilots on flight n-177! ""It's too hard! Too many variables to control! Frankly speaking, the slingshot effect can't control the running speed and direction precisely at all. Even experienced drivers won't regard it as a conventional acceleration and deceleration method! "

"It's just nonsense!"

"They are crazy!"

The commander's face was expressionless, and he clenched his fist. It seemed that he was struggling with something.

Standing nearby, Yang Wu took a silent look at him, only asking.

"Is it worth it?"

A city takes risks for a ship.

Is it really worth it?

……

To be honest, it didn't take much time for the boat to think about whether it was worth it.

As a scholar, there is only one problem he is considering now, and there is the optimal solution in the current situation.

Precise parameters are like vertical stacked blocks. No matter which parameter is adjusted, a little carelessness may lead to extremely serious navigation accidents.

Without accident, they will have 11 hours to fly in geosynchronous orbit and have a great possibility of colliding with the space station Tianzhou.

To be honest, the window period is very short, not to mention the most complicated manual driving.

His calculation must be accurate, not even a small error.

To survive, he must make good use of every division of labor and quality reserve, ignite the side engine at the critical moment, and use the slingshot effect to complete the final deceleration.

Standing beside the boat, fan Sheng, the engineer, said suddenly, with a desperate face.

"I bet we're targeted."

"Aim?"

"We are like a missile now, hitting the Tianzhou straightly," fan Sheng said with a bitter expression on his face. "In their eyes, it must be like this. The orbital defense weapons will respond. If I were them, I would not allow such a thing to happen. "

"I don't rule it out, but I'm sure it won't happen." Looking at fan Sheng, the boat was silent for a while, reaching out and patting him on the shoulder. "Go to the cabin and have a rest. I want to be alone for a while."

Fan Sheng: "can you tell me, what are you going to do?"

Land boat: "slingshot effect."

Fan Sheng opened his mouth and after a long time, a word came out of his throat.

"It's crazy..."

After leaving the cockpit, fan Sheng returned to the cabin, trying to make his expression not too heavy, and silently walked back to his position and sat down.

Professor Leonard sighed and looked sadly at the starry sky outside the cockpit. "Are we dead? Who can give me a get it? "

Fan Sheng: " Not so desperate, but not so good

Eleven hours of waiting is so long.

The eyes of the world are all involved in the flight that is coming from the deep air and out of control.

The orbital residents who had no time to evacuate spontaneously came to the landing window to pray for the approaching spacecraft and their own destiny.

100 kilometers!

10km!

Last mile!

In their pupils, they saw only a dark shadow getting closer and closer, which eventually obscured their vision of the moon.

The expression in people's eyes gradually despaired.

At this distance scale, it is impossible to stop at the current speed.

However

Just then, a miracle happened.

Even if it is infinitely close to the astronomical distance, the huge body of the ship finally does not collide, but passes by the Tianzhou.

The boat in the cockpit slowly breathed a sigh of relief. Looking at the re calculated route on the hologram, the whole person sat in the cockpit.

The impulse obtained from the Earth Moon system made flight n-177 slow down successfully. With the active deceleration system that has been activated, they will be able to join the patrol ships sent by the Pan Asian first fleet in two days at most.

Not two weeks later

Even in the space history, it will be a textbook demonstration and an epic victory!

Think of here, land boat tired face, can't help but raise a smile of relief.

When I return to the earth, I can be proud for a while

In the cabin, nervous Professor Leonard stared out of the window at the towering fortress.

On this astronomical scale, he could even see clearly the orbital residents standing in front of the French windows looking out at them.

On the other side, I saw him and them, and even many people were waving to them excitedly.

This is probably the greatest moment in human history.At least, one!

A man from 100 years ago saved a runaway flight and everyone on it.

And even at the last moment, people still don't give up hope and choose to believe in each other.

"In our time, we usually planned for the worst, even though I was not a pessimist myself..."

He took off his hat and put it in his arms. Yang Wu looked at the commander and said solemnly, "it's your courage that saved more than 200 passengers."

"We also plan for the worst, Comrade Yang from 2050..." Taking a deep breath of cold air, the commander's tight shoulders relaxed at last, and he responded with a slightly relaxed smile, "just by contrast, there are so many people who believe in us."

"Even for the sake of those who trust us, I don't want to let them down."

This disaster will make the Pan Asian people more united.

Although, similar things, he doesn't want to have a second time

On flight n-177.

Cheers and cheers rang out again, and the atmosphere was like a festival.

The spacecraft passing through the synchronous orbit is sailing slowly from the back of the earth to the sun.

Just as overlooking the sunrise, the brightness of the morning light up the blue horizon. In the light of mottled brilliance, the planet is so beautiful, clear clouds and oceans, leading the eyes of all people.

The child in front of the window, looking at the shocking scene outside the window, clutched his hand tightly, like grasping his dream.

He didn't know that he had just experienced the most dangerous moment in his life.

All he knew was that he was born on Mars and saw the most spectacular sunrise in his life.

Looking back excitedly, he looked at his mother.

"Mother, is that the earth?"

The childish milk sound is full of yearning for beautiful things.

The mother sitting next to him smiled and said softly.

"Yes."

"That's where my mother was born..."
