"What did you say? The grounding point is exactly 2.8 meters away from the central axis, exactly?" Shen Yansi finally showed a hint of shock at this moment: "Are you sure?"

"Team leader, I went to school and know numbers." The leader of the investigation team said helplessly: "Not only me, but two team members also saw it. It's impossible for all three pairs of eyes to see it wrong!"

"Team leader, even the autopilot can't fly so accurately!" The leader of the investigation team really opened his eyes today. Even now, he still can't hide the shock in his heart.

Of course Shen Yansi knew what 2.8 meters meant. Even though he had seen wind and waves, his heart was still filled with waves.

It was almost machine-like precision, so precise that it felt unreal.

The main wheelbase of the 737-800 aircraft is 5.7 meters. If the aircraft really lands on the central axis of the river, then the distance between the two main wheel touchdown points and the central axis should be 2.85 meters. However, Xu Xian's The grounding point of the Xingyou 6233 aircraft controlled was 2.8 meters away from the central axis, and the error was only five centimeters, which is almost negligible.

God-like operation!

"Team leader, if the grounding point of the right main wheel does not crack, thus affecting the direction of the aircraft, the aircraft should be able to pass through the bridge and culvert." Perhaps because he saw something amazing, the leader of the investigation team seemed to be very talkative: "This Is it really controlled by a co-pilot? It’s a miracle, isn’t it, team leader?”

"Okay! The technical team has started the soil analysis of Kunyang Airport? Contact me immediately when you have the results, and go ahead!" Shen Yansi stopped the chattering leader of the investigation team: "By the way, all investigation results are strictly Keep it confidential. You should know the seriousness of the matter this time. If the contents of the investigation are leaked and any unexpected changes occur, we will all be in trouble, remember?"

This incident is the most serious accident in the history of domestic civil aviation in the past 20 years, with nearly 130 people injured, which is a record. If it is not handled well, it will cause an uproar. Therefore, for every detail, the entire The investigation team must strictly guard against it. If some of it is exposed and maliciously interpreted by outsiders, it will be a disaster.

"I know, I know, don't worry, team leader!" the investigation team leader assured. This is also related to his vital interests, and he will definitely be careful.

"It is best to send me all the images of the emergency landing site in video form, and attach an explanation to me. Just tell me the facts and data, without any subjective judgment." Shen Yansi instructed.

"Okay, okay!" the investigation team leader responded repeatedly: "Team leader, I want to ask you one thing. Let me participate in the next in-depth investigation of the co-pilot. I'm really curious about what kind of person he is."

Although the investigation captain was a member of the investigation team, after some on-site investigations, he increasingly discovered that the pilot operating at that time was simply a monster. The key point is that the technical level of this monster was just a rookie who had just entered the first co-pilot position. , it’s really a strange news.

A few blue veins appeared on Shen Yansi's forehead: "Get your position right and don't act crazy all day long."

"Team leader, team leader, if you really don't think about it, just take me with you. Don't let me go out in the field every day." The leader of the investigation team was still chattering.

This investigation team is dedicated to field work and does not need to be responsible for interviews and investigations. Of course, this is the norm. However, this is not a hard and fast rule. If the leader of the investigation team allows it, the team leader cannot temporarily do indoor work. work.

"A bunch of nonsense!" Shen Yansi hung up the phone directly.

When he turned around, Xu Xian was also looking towards him.

"It seems that I underestimated you." Shen Yansi put away his mobile phone and sat back down: "You can't judge a person by his appearance. It is true that talented people have emerged from generation to generation, and each has led the way for hundreds of years."

Xu Xian raised his eyebrows: "Team Leader Shen's words are serious."

"But, isn't there an old saying?" Shen Yansi said with a smile: "Those who drown are all people who know how to swim. Of course, it might just be a coincidence, right? I think you have to start worrying about Dianyun Airport and Kunming now. Yang Airport landing analysis report. If any of these landing analysis shows that there is a sufficient probability of a successful landing, it seems that you should consider preparing to leave this industry forever."

"Of course, I heard that he hit his head and seems to have some amnesia. Maybe he will fail the physical examination later, so there is no need to think so much."

Xu Xian felt nervous. The leader of the investigation team, who seemed kind and friendly at first, seemed not as easy to deal with as he seemed.

"Of course I believe in the fairness of the bureau." Xu Xian smiled and said, "Is there anything else you want to ask?"

Shen Yansi waved to the note-taker, who understood and handed the record of the conversation to Shen Yansi. Shen Yansi took it, glanced at the record of the conversation, compared it with the originally expected question items, and found that After almost a while, he said, "No, that's it for today. Thank you for your hard work!"

Xu Xian nodded: "Okay, I won't give it away!"

After saying that, Xu Xian slowly closed his eyes and rested his mind, and ignored Shen Yansi.

Shen Yansi smiled. He was indeed a young man! His aggressive attitude just now must have made Xu Xian unhappy.

...

Air Traffic Management Dianyun Airport Branch, Safety Supervision Division.

"So this happened when you two were changing shifts?" The director of the Safety Supervision Department knocked on the table. In front of him, two tower controllers stood obediently.

One of them was Zheng Sheng, the tower controller who commanded Star Tour 6233 that day, and the other was Lin Yuan, the tower controller on the shift ahead of Zheng Sheng.

"Director, this matter has nothing to do with me!" Lin Yuan said very innocently: "The incident happened after I changed shifts. I was no longer in the control room at that time."

The director of the Safety Supervision Department glanced at Zheng Sheng: "Really? Lin Yuan didn't lie?"

Zheng Sheng nodded: "Yeah, Lin Yuan had already left at that time, and I was responsible for the entire command of Star Tour 6233. The surveillance video in the control room should have been recorded."

At that time, Zheng Sheng came to pick up Lin Yuan's shift, and the two of them chatted casually for a few words and then separated. After Lin Yuan left, something happened to Xingyu 6233. In the whole incident, the tower controller in front was indeed not involved at all.

"Were you commanding the whole process?" The director of the Safety Supervision Department grabbed a stack of paper materials at hand and threw them directly at Zheng Sheng: "This is the radio communication record of the Star Tour 6233 incident. Take a look at what's there. Problem?"

Zheng Sheng picked up the papers scattered on the ground one by one. Just as the director of the Safety Supervision Department said, the entire Star Tour 6233 incident was printed on the control and the crew's dialogue. He compared it paragraph by paragraph.

The incident did not last long, and there were not many conversation records. In addition, the incident had only happened not long ago, so Zheng Sheng's memory was still quite clear, so there was no doubt about the comparison process.

After a while, Zheng Sheng confirmed: "Director, this is no problem."

"No problem, that's good, otherwise I will blame a good person." The director of the Safety Supervision Department suddenly said: "The Southwest Air Traffic Control Bureau is run by your family, right?"

"Huh?" Zheng Sheng didn't understand what the director of the Safety Supervision Department meant.

The director of the Safety Supervision Department smiled and said: "It turns out not to be the case! Then why do we have the entire Air Traffic Control Bureau to take the blame for the mistake you made?"

Zheng Sheng's heart trembled: "Director, are you referring to the emergency landing permit on the Kunyang River?"

"You know!" The director of the Safety Supervision Department sneered: "Do you know how much pressure there is on the General Administration now? More than 130 people were injured, and more than 30 people were seriously injured. The last time there were such heavy casualties, there were still more.

Thirty-six years later, a major event that happens once in thirty-six years has happened to us. Have you forgotten how miserable the Northeast Bureau was after the air crash thirty-six years ago? Didn't the seniors tell you? Do you want to

Is the Southwest Bureau making the same mistake again?"

The air crash thirty-six years ago was the most serious accident in domestic history. Although no one died in the Kunyang River emergency landing incident, there were too many injured and the impact was huge. As the directly involved Dianyun Airport control,

The airport management branch is also afraid of getting involved in this dispute.

"Director, isn't this different?" Zheng Sheng was also told that he felt guilty. The main reason was that the plane crash thirty-six years ago was too deep into his bones, and the director of the Safety Supervision Department actually reported this emergency landing in Kunyang River.

The incident is similar to the air crash thirty-six years ago. This shows how serious the Kunyang River emergency landing incident was.

"What's the difference? You didn't give us the emergency landing permission?" the director of the Supervision Department snorted.

Until now, Zheng Sheng still doesn't think there is anything wrong with him: "There is nothing we can do about this!"

"Okay, okay! That bastard Fang Yuan is also responsible for this matter." The director of the Supervision Department gritted his teeth and said: "Forget it, fortunately we are only involved. Even if there is a problem, it is only a minor responsibility.

Fortunately! Fortunately!"

By this time, everyone wanted to distance themselves from the crash landing incident.

Fang Yuan was the duty supervisor who should have been present that day, and the responsibility for this dereliction of duty cannot be escaped.

"You two sit down and compare the communication recordings later. If you have any questions, I'll ask you in person. Lin Yuan, you were the one who was in contact before the plane took off, right?" asked the director of the Supervision Department.

Lin Yuan quickly agreed: "That's right, Director! I changed shifts after I gave the takeoff permission. The tower frequency during the taxiing phase was all communicated to me."

"Okay, then don't leave yet. You can leave after we pass the ground stage." The director of the Supervision Department said, "This is all routine work, so don't panic, kid."

Hearing this, Lin Yuan instantly relaxed and said with a smile: "It should, it should. Director, if you have any questions, just ask."

Lin Yuan did not doubt the words of the director of the Supervision Department. If there was anything to ask during the ground stage, it was just a formality. It would only take five or six sentences in total. If there were no surprises, it would probably be done within ten minutes.

.

Their regulatory responsibilities are not big to begin with. As long as there are no problems with today's questioning, there is no need to worry about it later.

The Director of the Supervision Office stood up. After sitting for a long time, his back felt a little sore. He stretched and pressed the play button, and a sound immediately sounded in the room.

"Tower, Xingyou 6233, in front of F1."

"Star Travel 6233, can enter runway 21 via F1, correct sea pressure 1011."

...

"Xingyou 6233, surface wind 040/01, runway 21, ready to take off."

"Runway 21, ready for takeoff, Star Travel 6233."

The Director of the Supervision Department paced back and forth in the room, stretching his muscles. When he heard the crew's response to take-off permission, the Director of the Supervision Department smiled and said: "Lin Yuan, it seems you can leave?"

Lin Yuan was also overjoyed: "Thank you, Director."

After saying that, he was ready to get up and leave.

But just when Lin Yuanjiang was about to get up, the crew's voice came from the playback device: "Star Travel 6233, then we will turn right to heading 230."

Not long after, Lin Yuan quickly replied: "Okay!"

The director of the Supervision Department stopped suddenly. Lin Yuan stood up as soon as he pressed down, and said in a cold voice: "What does it mean to turn right to heading 230?"

"That's right. The clearance at that time was to turn right to heading 230 after takeoff." Lin Yuan replied immediately.

In fact, Xu Xian went without saying this. However, Xu Xian was out of habit and took the initiative to contact the control tower when he turned right.

Lin Yuan was already preparing to change shifts at that time. He casually confirmed Xu Xian's words and started to change shifts with Zheng Sheng.

The director of the Supervision Department's face darkened slightly: "Why turn right? Isn't it said that right turns after takeoff are not allowed as much as possible?"

There are such tall buildings near the airport. The flight procedures at the airport must not be the same as before, otherwise it will definitely affect flight safety.

Therefore, after the Xinfeng Building reached a certain height, the airport modified some flight procedures and imposed additional requirements for control.

One of the points is that for aircraft taking off from runway 21/22, unless there are special circumstances, the command is not allowed to turn right after takeoff. That is to prevent power system failure after turning right and the Xinfeng Building becoming an obstacle when the aircraft wants to return.

If for special reasons it is necessary to direct the aircraft to turn right after takeoff, the flight path must not be greater than 240 degrees. The Bureau has verified that as long as the flight path after takeoff is not greater than 240 degrees, even if it is to return to Yunnan Airport, Xinfeng Building will not become a

Obstacles to return.

"Takeoff on Runway 22 is affected, so we need to turn right first," Lin Yuan said.

"Who gave the release?" The director of the Supervision Department said in a cold voice: "Isn't it the release frequency?"
