The night before the test flight, Xu Cang chatted with Chen Guoli for a while, but finally couldn't stand the cold wind outside and went back to the airport hotel. But when he arrived at the corridor of the guest room, he saw a hunched figure standing at the door of his room. When he got closer, he found that it was Bi Lin.
Bi Lin saw Xu Cang coming back and asked with a smile, "Just now I saw you talking to Guo Li outside?"
"Well, I just talked to Teacher Chen about tomorrow's plan." Xu Cang saw that Bi Lin still had something to say, so he opened the door first: "Dean, how about we go into the room and talk?"
Bi Lin nodded: "I have something to tell you, let's go."
The two entered Xu Cang's room. Bi Lin found a chair and sat down. He raised his hand to stop Xu Cang from pouring him some water: "Stop busying yourself. Sit down and talk."
"Oh!" Xu Cang sat down beside the bed and said, "Dean, there is something important that I have to trouble you to come here specially."
Bi Lin pursed his lips. It didn't look like something that was easy to say. However, after hesitating for a moment, Bi Lin still said, "Xu Cang, what did Guo Li say to you just now?"
"Huh?" Xu Cang was stunned, but he didn't hide it: "Instructor Chen said that we might encounter downwash in the subsequent stage of the right turn during the initial climb, so I should be careful."
Bi Lin hummed, "It's the stage of entering the canyon. This year is indeed unusual. Normally, the southwest wind should turn into the north wind at this time."
"Moreover, the southwest wind seems to be particularly strong." Xu Cang added.
"Yes, it is very strong. I told you about the national strength. I asked someone to evaluate it..."
Xu Cang didn't expect that Bi Lin not only knew about this matter, but also made a special assessment. He immediately asked, "What is the result?"
However, Bi Lin did not answer immediately, but said to Xu Cang earnestly: "Xu Cang, tomorrow when you pass the initial climbing stage and enter the canyon area, after you feel the impact of the downdraft, as long as you feel that it will affect the final obstacle crossing, start the other engine immediately."
There was some time between entering the canyon and encountering the last obstacle, allowing the crew to react. At the same time, the altitude was not high, so starting the engine was relatively quick, unlike the high-altitude approach that required several attempts.
However, what Bi Lin said undoubtedly revealed a very serious fact, that is, the downwash jet stream does have the possibility of causing the aircraft to be unable to overcome obstacles.
"Dean, what are the results of the evaluation?"
Bi Lin sighed, "According to the data provided by the Meteorological Bureau, in the past month, there were only about five or six days with winds strong enough to allow a single-engine aircraft to complete the final obstacle clearance. The rest of the time, the winds were too strong, and the downwash formed by the winds would suppress the aircraft and prevent it from ascending. The last obstacle turned out to be the most fatal, which is really ridiculous."
Generally speaking, the initial climb phase in a single-engine situation is the most dangerous, especially before retracting the landing gear. On the contrary, once the aircraft enters a smooth state, the subsequent obstacle threat is not that great. After all, not all places have insurmountable chasms like the Tianshan Mountains.
As long as the aircraft has completed the initial climb and gained a slight altitude, subsequent obstacles will not be a problem.
Even for Qitai Airport, to reach the last obstacle in a smooth state, it is actually sufficient to maintain a climb gradient of about 1.2%.
A 1.2% climb gradient is definitely not a high requirement, even for a single-engine aircraft. At least even for a single-engine aircraft, aircraft can generally maintain a climb gradient of more than 3%.
However, this seemingly not-so-strict requirement became the last straw that broke the camel's back.
"Only five or six days a month?" Xu Cang's face became extremely solemn. This ratio was too high. If there were only five or six days in a month where problems would occur, then Xu Cang would just accept it. After all, many things could not be perfect.
However, the fact is the opposite. There is only a chance of survival for five or six days a month, and the rest of the time he will definitely die. How can Xu Cang accept this?
"Does that mean there is absolutely no chance of survival during the rest of the time?" Xu Cang asked.
Perhaps because he had opened up the topic, Bi Lin answered quickly this time: "In theory, yes. There was actually such a part in the previous single-engine verification of the military transport aircraft. However, the day of that verification was very good, and the southwest wind happened to weaken, so the transport aircraft was not greatly affected, and finally the verification was completed."
This is what Bi Lin and Di Qingquan had said before that the verification results of the military transport aircraft were not ideal. To be honest, the verification results were highly probabilistic and not universal. If it were to happen again, the results would probably be different.
Xu Cang's expression gradually turned gloomy: "Then why did the transport plane pass the verification result?"
Bi Lin's gaze was distant and indifferent, but the complexity contained in it was difficult for Xu Cang to fully appreciate.
"Xu Cang, sometimes human life is more important than Mount Tai, and sometimes it is as light as a feather. Do you understand?"
Xu Cang's face turned pale. Of course he understood what Bi Lin meant, but for someone like Xu Cang who had not experienced that era, there were some concepts that he could not accept.
Xu Cang was more relieved about the wind shear Chen Guoli mentioned. It was indeed a matter of probability. If you were unlucky and encountered severe wind shear, even a plane with two normal engines would not be able to withstand it. There were very few flight procedures in the world that took such uncertainties as wind shear into consideration.
However, the subsequent downwash jet is no longer a matter of probability, but a stable and realistic threat. With only a one-sixth theoretical probability of survival, that is basically a verdict. As long as Qitai Airport encounters a single jet, it is basically a death sentence?
Xu Cang hesitated for a moment, and finally asked: "Can't the design institute modify the program? Don't they know about the existence of the downdraft?"
"Do you think the design institute didn't know about it before?" Bi Lin asked back.
Xu Cang was stunned: "Then why did they design this meaningless program?"
As soon as the words came out, Xu Cang reacted immediately. If it wasn't intentional by the people in the design institute, then there was only one possibility...
"They have no other solution?" Xu Cang asked blankly.
"Xu Cang, there are very few possible airport sites there, and Qitai is a relatively good one. And the design institute can't come up with a better plan."
Bi Lin's words were so heavy, and this kind of thing could not be left to Boeing's design department. Of course, Xu Cang also believed in the ability of the design institute. If they said there was no way, then there was a high probability that Boeing could not do anything either.
"Guoli discovered it himself, so I don't have to explain it to him in detail. I gave him the same instructions before. As soon as you sense the possibility of an insurmountable obstacle, start the engine immediately and terminate the verification. Did he tell you just now?"
"Yes." Xu Cang said, "However, I thought it was his personal opinion just now. I didn't expect that it was your opinion."
Bi Lin sighed and said, "This is an objective limitation that cannot be influenced by human power. Xu Cang, you don't have to worry about it. Tomorrow, your verification only needs to ensure stable obstacle crossing during the initial climbing phase. For subsequent obstacle crossings... just a taste."
"Does that mean we just ignore the problem of the rapids?" Xu Cang asked back.
Bi Lin didn't say anything this time, but his meaning was very clear.
For a moment, the whole room fell into an eerie silence.
Finally, after about a minute, Xu Cang said, "I want to find another way for them to survive."
"Xu Cang, this is a dead end, you can't change anything." Bi Lin said sternly: "I'll say it again, after you complete the initial climb verification, you can tentatively conduct subsequent verifications. Xu Cang, it's OK if you have this intention, but this is not something you can change."
Xu Cang's eyes blinked, and it seemed that his brain was working rapidly. After a moment, he gave his answer: "I want to try."
"Xu Cang!" Bi Lin stood up suddenly: "Some things can be done because they have the possibility of success, but some things cannot be done because they are meaningless."
However, some images were already flashing in Xu Cang's mind: "Maybe, I can really find a way."
…
There is a slightly lower hill not far from Qitai Airport , which is covered with a large amount of snow. Not only can no trees or plants be seen, even the rocks cannot be seen.
At this moment, there were two small dots on the hillside moving slowly upwards. When looking closer, they turned out to be two people wrapped tightly.
In addition to wearing thick warm clothes, the two men also carried huge bags on their backs, just like climbers challenging their limits. However, this is not the main peak of Tianshan Mountain, and the altitude is not so high, so it is a bit cold, and walking on the snow is also very difficult, but the risk factor is not great.
Of the two, the one in the black down jacket was walking in front, and the guy in the white down jacket was panting behind him: "Brother Ji, do you think there is something wrong with the hospital? We are surveying and mapping, not mountaineering. This must be exhausting."
The two were surveyors from the National Design Institute. The one in front was called Ji Dong, and the one behind was Wang Wen. Ji Dong was an old employee and had no complaints about this kind of work, but Wang Wen was different. He had just joined the surveying team not long ago, and he couldn't stand this kind of physical work. He kept complaining along the way, which annoyed Ji Dong.
"I'm not asking you to climb Mount Everest, why are you yelling? I don't think you're that tired, and your voice is very loud." Ji Dong said dissatisfiedly.
Originally, Wang Wen should have been more honest as a newcomer after being scolded by the old employee. But Wang Wen was born with social skills and not only did he not stop talking, but he became more excited: "Brother Ji, I heard from the hospital that your family has a large orchard and is very rich. Why do you still come to the surveying team? It's so hard here."
"Can you shut up?" Ji Dong couldn't stand the new guy assigned to him. The surveying team often had to go out on field trips, which involved a lot of things, so there would be situations where the old would guide the new. For example, Wang Wen was assigned to Ji Dong by the team, and he was asked to guide Wang Wen for a period of time.
Ji Dong said, looking up at the mountaintop that was already within reach: "We're almost there, at the top of the mountain..."
"Set up the camera and shoot the planes in the canyon." Wang Wen muttered to himself.
"Stop being so careless. Keep an eye on the camera angle. It must be shot clearly. The video behind is important reference material for the hospital. If it's blurry, forget about getting a permanent job."
"Okay, okay!" Wang Wen agreed dejectedly, "But didn't the hospital say that single-engine flights are not allowed in this canyon? Then what's the point of verifying it?"
Veins popped up on Ji Dong's forehead, and he was too lazy to care about Wang Wen anymore. He climbed up a few more steps and reached the top of the mountain. But just as he reached the top of the mountain, Ji Dong felt a strong wind and his body was almost unstable. Fortunately, the stick in his right hand was stuck in the snow to stabilize his body.
Wang Wen, who followed, was also caught off guard , but Ji Dong was quick-witted and grabbed Wang Wen, thus preventing him from falling down.
Wang Wen bent his body slightly and lowered his center of gravity: "What the hell, the wind is too strong."
Although Wang Wen is a chatterbox, he is still able to do his job when he reaches the top of the mountain. He immediately puts down his backpack and takes out the camera equipment.
"It's that gap!" After Ji Dong got used to the strong wind, he still felt it was okay. It was the gap in the mountains in the distance to the right front.
At this moment, Ji Dong and Wang Wen were at the inner bend of the U-shaped canyon. Ji Dong was pointing to the gap in the outer mountain range. The southwest wind blew and was blocked by the mountains outside the canyon.
Some of them go up along the hillside, then go around the mountain range and form a downrushing rapids on the leeward slope, while some of them rush in directly from the gap in the mountain range.
The gap was like a flood outlet. The violent airflow became even more uncontrollable after being squeezed through the mountain pass, and the area facing the mountain pass would suffer from extremely terrifying wind impacts, so that even from a long distance, Ji Dong could still feel the incredibly strong wind.
"Where is the plane?" Wang Wen set up the tripod and installed the camera on it, his eyes already searching for the plane in the canyon below.
Ji Dong also looked down at the canyon, and soon saw a white-painted plane not far away in the sky: "Over there!"
"Yes!" Wang Wen quickly controlled the camera to shoot at the plane, but soon, Wang Wen had a question in his mind: "Brother, something seems wrong."
Ji Dong leaned half of his body weight on the stick, still thinking about taking a break, when he heard Wang Wen's words: "What's wrong?"
Wang Wen said in an uncertain tone: "The plane seems to be descending. How could it descend?"
…
"Why is it descending?" In the tower control room, Zhou Yanping looked at the radar monitoring screen and noticed the abnormality at the first time.
"What?" Wang Li didn't look at the radar screen just now. At this moment, he immediately turned back and looked at the radar screen. Sure enough, the altitude of plane 1533 was slowly decreasing.
Although the rate of descent was very small, it was a very bad sign. No one would think that the crew was actively trying to slow down the descent, unless they were actively seeking death.
Yes, the final climb gradient requirement is very small, and the crew has some margin. But this does not mean that the aircraft can descend. Even if there is some margin, it must not be squandered.
Wang Lifu's face turned ugly when he saw the plane start to drop in altitude. Even with only one engine, the crew must have maintained nearly full thrust. Even under such a premise, the downwash could still suppress the plane so that it could not even maintain a level flight.
This is the power of nature, an irresistible power.
"Is it still not working?" Wang Li turned to look at Bi Lin with an extremely ugly expression: "Mr. Bi, do you want to continue?"
Zhou Yanping didn't know about the downdraft, he just felt that the plane was descending instead of ascending and he could tell there was something wrong. As a single-engine plane, it would naturally climb at all costs, how could it descend? This was too unreasonable.
"Mr. Bi, what is going on?" Zhou Yanping asked curiously.
Yue Sheng and Ma Cheng didn't know how to fly, but that didn't mean they couldn't understand the atmosphere in the control room. The icy feeling that was almost condensed into substance made Yue Sheng and Ma Cheng feel quite uncomfortable.
As the source of the coldness, Bi Lin's face was gloomier than ever. After three or four seconds of silence, he finally let out a breath: "Let Xu Cang restart the engine and verify the termination."
Wang Li sighed somewhat dejectedly. Although he had some fantasies, when it really came to this point, he still felt uncontrollable disappointment.
Wang Li didn't say anything else, but gently patted the tower controller on the shoulder: "Repeat what Mr. Bi said."
The controller nodded and immediately spoke into the microphone: "1533, verification terminated, please restart the engine and climb to a safe altitude."
Even if the downwash jet is violent, if both engines are working together, the downwash jet cannot suppress the aircraft, and it can only escape the terrain threat in a short time.
However, Xu Cang's extremely firm voice soon came from the loudspeaker: "Continue the verification."
Wang Li and Bi Lin were stunned for two seconds, and then Wang Li grabbed the microphone and said, "Xu Cang, right? I'm Wang Li, the station chief of Qitai Airport. Didn't you notice that the plane has descended? You still want to continue?"
If the plane could maintain level flight, Wang Li and Bi Lin might have let Xu Cang continue to try, but the plane had already begun to descend in altitude. Even if the amplitude was small and would not cause a terrain threat for the time being, it would be impossible to climb over the obstacle behind.
"That's right, the verification continues!" Wang Li's response was still Xu Cang's unquestionable words.
In the cockpit, Chen Guoli had one hand on the start switch of engine No. 1. Chen Guoli obeyed the tower's instructions very well. If the tower control asked him to stop the verification, he would stop. If the tower control asked him to restart the engine, he would restart it.
However, Xu Cang's answer made Chen Guoli feel a little at a loss: "Xu Cang, don't you want to restart the engine?"
"I said go ahead, ignore the engine for now." Xu Cang said in a deep voice.
Once the engine is restarted, even if the engine thrust handle is placed at slow speed after starting, it is still different from single-engine. Engine slow speed and engine shutdown are two completely different concepts. Apart from other things, at least when the engine is slow, the tail nozzle is still spraying backwards, and the positive thrust is still generated, although it is quite small.
However, once the engine is turned off, wind resistance will be generated. The difference between the two is huge. If the engine is restarted, even if the vehicle slows down, the subsequent verification will be completely meaningless.
Chen Guoli hesitated for a moment, and indeed fulfilled his previous promise, and he followed Xu Cang's opinion. However, Chen Guoli was not afraid of death, but that did not mean he could accept a meaningless death.
The plane was destined to fail to overcome the last obstacle the moment it descended, so what was the point of the subsequent verification?
"Xu Cang, we can't get over it." Chen Guoli said dimly.
At this moment, Xu Cang increased the speed of the No. 2 engine to its maximum and at the same time intentionally pulled the stick back so that the airspeed was decreasing at an extremely slow rate.
However, the altitude can be maintained at the cost of maximum thrust and slow loss of airspeed. However, this speed-for-altitude option cannot last too long.
At this time, the plane was still flying forward according to the program, but with every second that passed, their chance of survival was squeezed. Restarting the engine took time, and if the decision was made too late, it might not be enough time to wait for the engine to start, or even if it started, it might not be enough to climb to a safe enough altitude.
Xu Cang looked at the mountain in the distance that was getting closer and closer. That was the last mountain blocking them.
Last night, Bi Lin told him that as long as the plane showed signs of descending, the verification should be terminated immediately. At that time, Xu Cang did not say anything, and Bi Lin thought that Xu Cang had acquiesced.
After all, no matter from which angle, this is a suggestion for the safety of the crew, and Xu Cang has no reason to refuse. In addition, this matter cannot be changed by human power.
The thrust of an engine is so great that even if Xu Cang is a god, he cannot double the thrust of the engine. And the downwash is there, and Xu Cang has no ability to eliminate it.
If that’s the case, what else can Xu Cang change?
The simpler the problem, the more impossible it is to change it once you hit a dead end. This is a simple climbing problem. The plane is underpowered and the airflow is suppressed. It just can't go up and can't climb over the mountain. Even gods can't save it.
It was for this reason that Chen Guoli couldn't understand why Xu Cang wanted to continue the verification. He listened to Xu Cang, but that didn't mean he agreed with Xu Cang's approach.
Just as Chen Guoli put forward his idea, an old voice was heard in the cockpit. This time it was not Wang Li, but Bi Lin.
"Xu Cang, some things cannot be forced. If you can't get over it, then you can't get over it. Let's end the verification."
When Chen Guoli heard Bi Lin's voice, his heart moved slightly, and he called out again: "Xu Cang?"
However, at this moment, Xu Cang's lips moved slightly: "No, there is another way. I said that I would find a way out for those who come after me."
Xu Cang's words echoed in the control room, causing Wang Li's face to become grim: "Why is this kid so ungrateful? No means no, doesn't he understand?"
"He even dared to test the prototype of the Trent 1000. What else is he afraid of?" Yue Sheng sneered.
In comparison, Zhou Yanping's face was not very good. From a personal point of view, he still liked it. Now he was worried that Xu Cang was possessed by a demon, so he wanted to complete the verification.
This is just like those pilots who have an overly strong desire to land the plane, and who force the landing regardless of whether the landing meets the standards, ultimately causing a disaster.
Among the three, Ma Cheng was the most indifferent. He didn't really care whether Xu Cang was dead or alive, he just watched the show.
Bi Lin looked at the position of the plane on the radar screen and continued to speak patiently into the microphone: "Xu Cang, don't act on impulse."
However, as soon as Bi Lin finished speaking, Wang Li came over and said, "Do you not understand what I am saying, or do you not understand the current situation? You are now unable to move up, down, left or right. If you do not terminate the verification, what do you want to do?"
Now the plane is surrounded by canyons on both sides, and is suppressed by downdrafts. It is impossible to descend. It is blocked from all directions, so how can it survive?
"Who said I was going to cross the mountain?" Xu Cang's voice suddenly rang out, causing the entire control room to fall silent.
Wang Li glanced at Bi Lin, his eyes full of confusion. He wanted to get an answer from Bi Lin because he had no idea what Xu Cang was talking about.
If we don't climb over the mountain, the plane will crash into it. How will we survive then?
Bi Lin was actually a little unsure, and he asked Xu Cang uncertainly: "Do you mean to return the same way?"
There's a dead end ahead, so why not just go back?
This is a fairly normal way of thinking, but airplanes are different from cars. Cars can move backwards, but airplanes cannot. There is a fundamental difference between the two.
"Return along the original route?" Wang Li probably understood what Bi Lin meant when he heard it.
However, there are many problems with this method, one of which is how should the plane turn around?
Fortunately, when Wang Li was puzzled, Xu Cang admitted it: "That's right, as long as we go in the opposite direction according to the single-engine procedure, we can go directly back to the airport."
"But your landing direction is wrong. How are you going to land with a tailwind of nearly fifty knots? Moreover, you cannot land on Runway 10. Its touchdown area is not strong enough. If you land on it, it will damage the runway." Wang Li said immediately.
Xu Cang's method seemed feasible at first glance, but in fact it had many loopholes. Because the single-engine takeoff procedure was returned from runway 28, the landing runway was actually runway 10.
As a result, the original headwind became a tailwind of nearly 50 knots. Fifty knots of tailwind, still on a slippery short runway, isn't this courting death?
Moreover, the Qitai Airport is very expensive, so in order to save costs, there is no way to strengthen the landing area of ​​Runway 10. According to Qitai's meteorological data over the past decade, Runway 10 is basically not used here. Therefore, from the beginning, Runway 10 does not have the function of landing, and the strength of its landing area is not enough. Once the plane hits it, the runway will be destroyed.
Qitai Airport is a place where it is very difficult to transport maintenance materials, so the progress of maintenance will be very slow. Once Qitai Airport is shut down for a long time, the impact will be relatively large.
Moreover, apart from anything else, there is an extremely fatal problem in Xu Cang's return plan.
"Also, how did you turn back?" Wang Li asked sternly, "The two sides of the canyon are so close to the plane that there is no room for turning. If you dare to turn in the canyon, you will crash into the mountain."
The turning radius of the plane is quite large, and considering the high speed of the plane, the turning radius is not small. However, the horizontal range of the plane is limited to a very small range due to the existence of the canyon, which cannot accommodate the turning of the plane.
Even if Xu Cang turned at a very large slope, it would be of no use at all. The only result would be crashing into the mountain.
"Xu Cang, your idea has actually been demonstrated by the design institute, but the turning radius cannot be eliminated, so this method will not work." Bi Lin said to Xu Cang.
The people in the design institute are not good-for-nothings, and they have considered almost all possibilities. Even the unconventional method of returning along the program has been demonstrated by the design institute, which shows how far they have been pushed.
Wang Li saw that the plane was not far from the last mountain, and he was anxious: "Xu Cang, there is not much time now. No means no. Let me tell you this, there is a mountain pass in front of you, and the design institute has also verified it. You can't enter that mountain. Behind it is the main range of Tianshan Mountain, with many peaks. Once you enter, you can't get out. Don't even think about relying on sticking to the right side of the canyon. After friction with the ground, the updraft on the right side of the hillside is already very weak and can't lift the plane. Moreover, although the mountain range on the right is lower than the left, the situation is more complicated. If you get too close, you will hit the mountain if you are not careful."
Wang Li seemed really anxious, and he told all the side doors that the design institute had previously demonstrated. Before the plane reached the last hill, it would pass through a gap in the mountain range.
If they really reach a dead end, some pilots might want to go through the gap to bypass the last mountain. But in fact, the real horror is behind the mountain pass. Behind it is the main range of Tianshan Mountain. Going there is just a temporary solution and a dead end.
The rising air current mentioned by Wang Li is the downdraft rushing down from the left hillside. After reaching the bottom of the valley, it is compressed by the terrain and must develop upwards along the right hillside.
This is easier to understand.
Since the plane cannot rise, why not use the updraft to help itself?
But in fact, as Wang Li said, due to the friction of the terrain, the airflow energy was reduced too much, and it was completely ineffective and could not lift the plane.
Wang Li said so much just to tell Xu Cang that the Design Institute has taken into consideration all the conventional, unconventional, orthodox and unconventional options.
If you say no, then it’s no!
In fact, even Zhou Yanping felt that the situation was hopeless, and he couldn't help but advise: "Xu Cang, forget it, no one will blame you."
However, just as Zhou Yanping finished speaking, Xu Cang's somewhat desolate voice rang out from the loudspeaker: "Dean, I saw the two people on the hill on the right. Did you arrange it? You still expect me to find the way, right?"
At this point, Bi Lin sighed. Yes, Ji Dong and Wang Wen were the ones he arranged on the top of the mountain. His plan was that if Xu Cang could really cross the top of the mountain under the rushing rapids, then the things Ji Dong and Wang Wen filmed would definitely be of great reference value. After all, no matter how sophisticated the digital images are, the video always gives people a more intuitive feeling.
But little did he know that as soon as Xu Cang's plane encountered the downwash, it was directly pressed down and began to descend, which immediately put an end to Bi Lin's idea of ​​continuing the verification.
It's too strong. The downwash is too strong and it is impossible to change it with human power.
"Yes, but I am willing to accept the reality now. Come back, safety is the most important thing." Bi Lin sighed.
However, what responded to Bi Lin was Xu Cang's extremely firm voice, which seemed more unshakable than the Tianshan Mountain!
"I, Xu Cang, am a person who will go down in history. Let's start from now. From today on, everyone who flies past here will chant my name!"
"Dean, just wait and see how I find a way out for future generations."
Bi Lin's eyes, which had been half closed, suddenly opened, and a sharp light burst out of them. At this moment, Yue Sheng could even feel that the temperature in the entire control room had dropped by several degrees.
This is the spirit and energy of the people who have come all the way from that era!
Obviously, Xu Cang's repeated rejections had made Bi Lin really angry.
However, suddenly, an extremely shocked voice rang out from the frozen control room: "How...how is this possible?"
That was Zhou Yanping's voice, but his voice was trembling and exuded incredible amazement.
"What's wrong?"
Wang Li looked at Zhou Yanping, who was staring blankly at the radar screen, and he followed Zhou Yanping's gaze. After a moment, Wang Li took a breath of cold air, and his right hand, which was supporting the console, couldn't stop shaking.
Seeing Bi Lin getting angry, Yue Sheng initially tried to persuade him. But suddenly, Yue Sheng discovered that there was no more anger on Bi Lin's face, only astonishment and surprise, and even his pupils were shaking.
Following Bi Lin's gaze towards the radar screen, Yue Sheng was a little puzzled. Not only Bi Lin, but also Wang Li and Zhou Yanpin were like sculptures. The muscles on their faces kept twitching, and it seemed as if their spirits had left their bodies.
"What?"
Yue Sheng looked at the radar screen. He could roughly understand what was on it, but he couldn't understand why Bi Lin and the others reacted so strongly.
“Huh!”
Suddenly, Yue Sheng's mind moved, and he seemed to have grasped something, but it was like a dream, not real.
"No, no, no!"
Suddenly, an idea that made Yue Sheng feel confused and frightened flashed through his mind. The idea was so unreasonable that Yue Sheng was terrified.
Yue Sheng's eyes were fixed on the light spot on the radar screen that represented the aircraft signal.
Time passed second by second. You could hear a pin drop in the control room. Only the barely audible sound of breathing indicated that time had not stopped.
But during that time that was still flowing, the light spot of the plane signal... stopped moving!
It just stayed there, weird and scary!
It's like the plane is hovering in the air!
