Juan is an air traffic controller at the Shenhai Hongqiao International Airport Tower.

When he was about to contact Air China flight CA4285, which was about to enter the landing route, he received an answering signal codenamed 7500 from the answering plane of flight CA4285.

"Oh no, CA4285 has been hijacked." Juan, who was familiar with all kinds of response signals, jumped up in surprise and shouted in panic.

As soon as the words were uttered, the air in the entire Tatano office seemed to freeze all at once. Everyone turned their heads and stared at Juan with solemn expressions.

"What, Xiaohu, you say it again."

At this time, Wang Guoping, the commander of the tower, immediately stood up and asked sternly.

"Report to Mr. Wang, I just received a response signal codenamed 7500 from CA4285." Juan said hurriedly.

"Confirmed?" Wang Guoping asked calmly.

"It's confirmed." Juan nodded solemnly.

"." After Wang Guoping cursed in a low voice, he then ordered in a loud voice: "Immediately activate the emergency plan against hijacking." ”

"Yes."

Everyone replied loudly in unison, and then entered their job responsibilities one after another.

********

What they call 7500 is actually a signal from the aircraft's transponder system with a code for the hijacked aircraft.

This transponder is an electronic device that automatically responds to a radio signal when it receives it.

During the flight, the air traffic controller will radio the transponder code assigned to him by guò, for example: "China Eastern Airlines 5101, transponder 0363", and then the pilot will manually enter the transponder code 0363 on the aircraft, and then the air traffic controller's radar screen will correctly display the aircraft's identity information.

The transponder code is a set of 4-digit occimal numbers, which are assigned to the transponder code through guò, and the air traffic controller can distinguish the aircraft.

There are 4096 transponder codes ranging from 0000 to 7777, some of which have specific meanings, such as 7500 for illegal acts (hijacking, etc.), 7600 for communication failures, and 7700 for emergencies.

When the pilot encounters special circumstances during the flight, the response code will be set to the above special code. In the event of a hijacking, the pilot sets the transponder to 7500.

In this way, even if the pilot does not call the ground by radio or other means, the ground controller can determine that the aircraft has been hijacked by the guò transponder signal.

Now Juan, that's what they're all about.

In fact, this is thanks to the fact that CA4285 has a very enjoyable captain with psychogenic zhì. It was he who quickly set the code of the transponder to 7500 the moment the robbers entered the cockpit, and informed the ground of the situation they were facing.

*********

CA4285 was hijacked, and the news was transmitted to the relevant units of the higher authorities at the first time.

The plane was hijacked, which was a big event, so all functional departments moved at the first time.

The Shenhai Municipal Party Committee and Municipal Government were almost like a great enemy, and immediately dispatched a crisis management team led by the mayor to Hongqiao International Airport.

At the same time, two Flying Dragon fighters of the Fourth Air Force of the Southeast Theater Theater, which had received an urgent call for help, urgently took to the air to reconnoiter the enemy's situation from a quiet distance.

**********

A small office made of glass houses in the Hongqiao Airport Tower is crowded with people.

Mayor Xiao Xuequn didn't care about greeting everyone, and asked directly: "What is the specific situation?" ”

"Report to the mayor that the hijacked plane is Air China's CA4285, model Boeing 747, with a total of 189 passengers, including eight crew members. The flight departs from Hotan at 10:40 a.m., stops at Wushi at 12:05 a.m., and departs from Wushi at 12:50 a.m. Half an hour ago, flight controllers at our tower received a hijacked signal from CA4285 codenamed 7500. At the moment we have lost all contact with CA4285 and we do not know anything about the situation on board at this time. The person in charge of the airport gave a brief report.

"Is there a list of passengers on board and their details." At this time, a leader of the National Security Bureau spoke.

"Yes, please take a look at the leaders here." The person in charge of the airport said and sent down a stack of materials that had been prepared for a long time.

"Comrades, the current situation is very serious, how to deal with this matter as a layman will not interfere, the specific is up to you experts to figure out, but I emphasize here that any action you take must ensure the safety of the passengers on board as the first priority. Please keep this in mind. After listening to a brief report, Xiao Xuequn spoke.

After Xiao Xuequn finished speaking, a group of emergency teams composed of elites from the military, police, national security, civil aviation and other departments began their busy work, and they were urgently discussing specific solutions.

The atmosphere was tense and busy.

"Xiao Zhang, come here, go and transfer this person's details to me." The person in charge of the Shenhai City State Security Bureau, who had been looking through the passenger list, said loudly to his secretary not far from him when he saw the three words Jin Haotian.

"Lao Cheng, is there any problem?" Xiao Xuequn couldn't help but ask curiously, and the others also watched him.

"Hehe, maybe things aren't as bad as we thought." Lao Cheng, the person in charge of the Shenhai City National Security Bureau, said with a relaxed face.

"Well, what do you mean?" Everyone asked puzzled.

"Hehe, I'm not sure yet, please allow me to buy a pass first." Lao Cheng smiled mysteriously.

"Hey, when did you sell Guanzi, Lao Cheng." Mayor Xiao Xuequn strongly expressed his dissatisfaction.

At this time, Lao Cheng's secretary walked over quickly with the computer in his hand, and said with a look of joy: "Director, it's really him." ”

"Really." Hearing this, Lao Cheng couldn't help but be overjoyed, snatched the computer and quickly looked at the information on it, then straightened up, and everyone looked at the screen in surprise and laughed very surely, "Okay, everyone don't be busy, with this kid on it, those robbers don't want to succeed." ”

"Hey, what's going on with Lao Cheng? Who is this Jin Haotian, and does he really have the ability to solve this matter? You know, he's just one person, so can't there be only one robber? Xiao Xuequn asked very puzzled.

"Jin Haotian? Mr. Kim's son-in-law? As soon as the words fell, a soldier next to him who was wearing a military uniform and looking at the rank of major general on his shoulder couldn't help but ask with a hint of surprise.

"Hehe, who else but him, if someone else I need to be so happy." Lao Cheng of the National Security Bureau said with a smile and gave a definite answer.

"Haha, if it's really him, then I can go home and wash and sleep." After listening to Lao Cheng's words, the major general couldn't help but say very relaxed.

"Hey, I'll say two, which language are you talking about, why can't I understand it, who is this Jin Haotian, and who is this Jin boss?" Xiao Xuequn protested with some dissatisfaction.

"Hahaha. Mayor Xiao, how many bosses does our military have? The Major General did not answer the rhetorical question.

"What's up, Commander-in-Chief Kim? So this Jin Haotian is the son of Commander-in-Chief Kim? Xiao Xuequn suddenly reacted and asked in surprise.

"Yes, yes." The major general, the old god, dragged a sentence of words.

"In this way, he is the grandson of Li Lao." Xiao Xuequn asked again.

"Hehe, Mayor Xiao, what you're asking is too novel, isn't Mr. Jin's son the grandson of Mr. Li." The Major General said teasingly.

"Is that the one who made Li Lao make a reward of 10 billion to hunt down the leaders involved in the island country last time?" Xiao Xuequn asked again.

"Haha, Lao Xiao, have you done your job well?" Lao Cheng of the National Security Bureau couldn't help but ridicule.

"To your sister's head, I said that the two of you drank at noon, since you know that the grandson of Mr. Jin's son-in-law, Mr. Li, is also on this plane, and he still doesn't pay attention to it so much, if something bad happens, who can afford it from you and me." Thinking that Li Lao was able to do such a thing as openly offering a reward of 10 billion yuan in order to avenge him, Xiao Xuequn couldn't help but feel afraid for a while, if this kid really died in this hijacking incident this time, then as the leader of the leading group of this anti-hijacking incident, he would definitely not be able to eat and walk around, and his life would end here. That Li Lao started a fire, and there are really few people in this country who can suppress it.

"Haha, why do you have to take care of it." The major general smiled heartily, and then said comfortingly: "Old Xiao relax, it's okay." You will have good news in the future, our young master Jin is not a gentleman who is not diligent in his limbs and does not distinguish between grains and grains, he has great skills. And I also tell you that if even he can't solve this matter, then our military really can't find someone who can solve it. ”

"That's right, it's the same on our side of national security. Don't worry, Mayor Xiao, this kid's ability is beyond our imagination, as long as he seizes the opportunity, those hijackers will only have the share of the king of Hades. Lao Cheng of the National Security Bureau also spoke.

"I said, where did you get all this confidence?" Xiao Xuequn asked speechlessly.

"Haha, Lao Xiao, you have also seen the skills of our Flying Dragon Special Combat Team in the Southeast Theater, what do you think of their level?" The Major General asked with a smile. "Strong is very strong, worthy of being the elite of the elite." Xiao Xuequn immediately replied, he had seen this Flying Dragon Special Combat Team more than once, and each time they used their exquisite skills and excellent military skills to conquer the big mayor.

"Then do you know that those young men of the Flying Dragon are all disciples and grandchildren of this kid." The major general said with a smile.

"What? Really? Xiao Xuequn couldn't believe his ears.

"Hehe, when did my old Wu tell a lie?" The major general said dissatisfied.

"What's going on?" Xiao Xuequn asked curiously.

"Hehe, a lot of things here involve military secrets, so I can't tell you in detail, but there is one thing I can tell you, ten years ago, this kid was the most elite special soldier in my Southeast Theater, no one, rich experience in actual combat, and countless enemies." Major General Wu said seriously.

"Rich experience in actual combat, killing countless enemies?" Suddenly, Xiao Xuequn suddenly had a realization in his heart, and he glanced at Major General Wu with a complicated expression and stopped speaking.

Major General Wu's words just now gave him too much information. And he knows this Major General Wu very well, this is a person who has one thing to say and seeks truth from facts, and he will definitely not talk nonsense just because Jin Haotian is a yagnate.

And in this case, both Major General Wu and Director Cheng of Guoan are so calm, which is enough to show that this Jin Yanei is a person with great ability, at least his ability is to conquer these two.

Thinking of this, his heart couldn't help but let go a lot.

At this time, there was a disturbance on the tower outside, and everyone's faces couldn't help but change greatly, and they hurriedly ran out.
