Chapter 12 Chapter Eleven

Just after 9:20, investigators from the Aichi Police Headquarters arrived at Nishiki Heavy Industries.Earlier, the director of the Xiaomaki Police Sub-bureau had led a large number of police officers to the scene to protect the safety cover.Tang Yuan and the others learned from the chief of the sub-bureau that the gangster who stole the helicopter threatened the government with Xinyang, a prototype of the fast-breeding reactor. Although it is hard to believe, this is an undeniable fact.The elderly director said with a livid face that no matter what, he must look for clues from the scene of Jinzhong Industry.

Criminal Minister Mu Gu came to the scene on behalf of the county police headquarters. He looked very calm in his fifties, and he could display his due calmness at critical moments. The theft of the helicopter of the Self-Defense Forces is indeed a major event, but usually the criminal minister will not go to the scene in person, and the appearance of Kigu also shows the seriousness of the situation. After Kigu arrived at the scene, he immediately went to the meeting room on the second floor of the Welfare Center where relevant personnel from Nishiki Heavy Industry gathered, hoping to establish a command headquarters there.Director Kasamatsu of the Technology Division agreed on the spot.

In several small rooms next to the command headquarters, the police are asking relevant personnel for information.Yuhara and Yamashita were also called into one of the rooms, and Kosaka, the police department of the special search team of the Aichi Prefectural Police Search Section 1, was waiting for them in the room.Kosaka's eyebrows, nose and jaw lines are very sharp. It is reasonable to say that he should be a certain age to be a police officer, but there are no wrinkles on his face at all, but he doesn't feel young. Hairy majesty.When Yu Yuan sat on the chair opposite him, he immediately felt that this terrifying feeling must be able to exert its power when he was facing criminals.

Two young detectives sat on either side of the Takasaka police department. "You should have heard what happened, right?" Kosaka looked at Yuhara and the others and asked. "Yes, I have generally heard about it." Tang Yuan replied. "Very good," Kosaka nodded, "First of all, I would like to convey to you what the police agency explained. Please urgently send personnel who are familiar with the helicopter to the scene, which is the Xinyang Power Plant on the Tsuruga Peninsula. The choice is up to you , But," Kosaka paused for a moment, staring at Yuyuan, "this is also an instruction from the Police Agency, and the wishes of the parties must be confirmed. If the parties refuse, they must not be forced."

It must be because it is currently impossible to predict what will happen next, and it is impossible to ensure personal safety, so I will be specially reminded.Yuhara licked his dry lips and said: "Okay, then I'll go." "No, I'll go." Yamashita also said, "GPS is my specialty." "You'd better stay with your wife, I'll go." Yamashita shook his head frequently. "What happened to Keita, it's impossible for me to stay here, and Machiko will feel uneasy seeing me doing nothing here. Please, let me go." Yuuhara sighed. "Then let's go together. As long as there are two of us, most problems should be solved."

Then, he turned to look at Kosaka and asked: "Is that okay?" "Of course there is no problem, then please two. We will prepare a helicopter, please take a helicopter to go there." After Kosaka finished speaking, he asked his subordinate sitting on his right: "Is the helicopter ready?" The subordinate was not tall, but his eyes were sharp. He glanced at his watch and replied, "It will take about ten minutes." "Ten minutes? How much time do you need to prepare?" Kosaka asked Yuhara and the others. "Just go get the information, five minutes is enough." Tang Yuan replied.

"Okay, then I'll take you five minutes first." Kosaka took out a piece of paper from the inside pocket of his suit and handed it to Yuhara.It was a copy of the threatening letter.The threatening letter, which begins with "everyone concerned," contained shocking content. "How is it?" Kosaka asked after noticing that Yuhara had finished reading. "It's too shocking." This is Tang Yuan's true feelings. Kosaka smiled lightly, instead of softening his expression, it emphasized his majesty even more. "I feel the same way, but have you thought of anything?"

"After reading the threatening letter?" "That's right." Kosaka looked at Yuhara with both eyes, and retracted his pointed chin. "Is there any content or words that allow you to imagine what the gangster looks like?" Tang Yuan listened and read the threatening letter again, but there was no word that made him feel special. "I don't feel anything." "Really?" Kosaka didn't seem too disappointed, and then asked Yamashita: "What about you?" "I don't have any special feelings either," Yamashita said, and couldn't help tilting his head, "It's just..."

"Just what? What did you find?" "No, it's not a discovery. I'm just a little concerned about the word 'bee'...the word 'sky bee'?" Yamashita looked at Yu Yuan and asked for his opinion. "It makes sense," Tang Yuan immediately understood, "It's true from what you said." "What do you mean?" Kosaka asked. Yamashita hesitated for a moment and said: "The official name of the stolen helicopter is CH─5XJ, but in order to distinguish it from the pre-modified CH─5XE, we call it 'Big B', the English letter B, which is taken from the name of this project 'B System Project' .”

"I see, so what?" "So, those involved call it 'bee'. Isn't the English word for bee bee? It happens to be the homonym of the English letter B." "It's really interesting." The police department showed sharp eyes, which should be the unique majesty of investigators, "Who knows about this?" "I didn't deliberately treat it as a secret." Yamashita looked at Tang Yuan for help. "It's normal for people related to the plan and people around to know about it," Tang Yuan added. "But the number of people who know is quite limited."

"Yeah...but the gangsters probably just happened to use the word 'bee'." Yuhara said, but Kosaka stopped him with his right hand. "We will judge this matter. Time is running out now, and I will ask the next question. I just heard Director Xiao Gao talk about the general situation of the helicopter being stolen. Could you please explain it in more detail?" "no problem." "This is Erping," Kosaka introduced the tall subordinate sitting on his left side, "He is responsible for computer crimes in the Crime Prevention Division, and he is a freak who graduated from the Department of Electronic Engineering, but I think he can understand your major. Just sent him here on secondment, so even with some expertise there is no problem." "Please take care of me." Er Ping nodded, and Tang Yuan and the others also bowed. "What we want to know is," Kosaka began to ask, "I hope you can tell us, what exactly did the gangster do? What should he do to make the super-large helicopter leave the hangar and fly away by itself." "Okay," Tang Yuan nodded, lowered his eyes for a few seconds, thinking about where to start.Then, he raised his head and looked at Kosaka and Erping's faces at the same time, "From the conclusion, the criminals transformed 'Big B' so that it can be operated by remote control." "Judging from the situation, it seems to be the case, but the question is can it be done easily?" "It can't be done easily." Yuyuan replied immediately, "If it is an ordinary helicopter, it is absolutely impossible. There is a manufacturer in the United States that sells special accessories that can transform decommissioned helicopters into remote control operations. It can't be done in one night. It's just that in the case of 'Big B', it's possible to do it with some kind of manipulation. Because it's a special helicopter." "What's special?" "Traditional helicopters transmit the pilot's control actions to the propeller through a mechanical connection, but the CH─5XJ can convert the pilot's operation content into electronic signals, which are then processed by the computer and converted into the most appropriate signals and sent to the Operate every part of the helicopter. The fly-by-wire flight control system is a very popular technology in fixed-wing aircraft, but in practical helicopters, CH─5XJ is the first example.” "Is this digital?" Er Bottle stopped recording and asked. "certainly." The early models of the F16 fighter used to use analog, but the recent fly-by-wire flight control systems are almost all digital. Kosaka folded his arms. "Is it possible to operate remotely by using this device?" "Just move your hands and feet, and use another method to input the signals that should have been sent by the joystick and so on into the computer." "You make it seem very simple." "It's just saying it with your mouth, but it's another thing to actually do it." "In short, did the criminals move their hands and feet, and let that helicopter fly into the sky in a way that seemed to be operating a toy remote control helicopter?" "No, no matter how powerful it is, it is impossible to achieve this level," Yuyuan shook his head, "The gangsters can only use remote control to drive the helicopter out of the hangar until it takes off. It is not too difficult to move on the ground , but taking off and flying is not as simple as a toy." "So, have other parts been tampered with?" "Yes. It should be said that that is the main part. The criminals should have activated the AFCS program." "AFCS?" "It's short for automatic flight control system, which is a highly automatic pilot device, which can be said to replace the pilot with a computer." "Oh." Kosaka leaned back slightly and smiled. "It's almost like a sci-fi movie." However, his eyes did not smile. "To what extent can it be automated?" Erbo asked. "As long as you enter the program in advance, you can take off automatically, and then you can automatically fly on the designated route. If you enter the program in advance, you can also hover at a certain point after the flight." "Isn't there no need for a pilot?" Kosaka was very surprised. "If it's just cruising, the pilot doesn't have to do almost anything, but landing is another story because it's difficult to do it in an automated way." "But still great." "Only that helicopter in the whole world can do it." Equipped with AFCS──This is the content of the "B System Plan".At the beginning, it was based on the premise of using this new technology that the CH─5XJ of the fly-by-wire flight control system was purchased. Yuyuan and Yamashita also sacrificed their families for this, and struggled for five years── "So, the criminals only need to enter the program in advance?" Kosaka asked.Tang Yuan tilted his head slightly and said: "This alone is not enough. The gangster must first drive the helicopter out of the hangar by remote control. This is operated in the standard mode, but for automatic take-off and automatic cruise on the designated route, the mode must be switched to activate AFCS. Another remote control." Kosaka looked at Erping and asked, "Do you understand?" "Understandable." Er Ping nodded and said to Tang Yuan, "But it shouldn't be too difficult." "As long as someone who understands the structure of AFCS should be fine." Tang Yuan replied. "What if it's you?" Kosaka asked, pointing at Yuhara's chest, "If you want to change what you just said, can you do it?" "It should be fine if you want to do it." Tang Yuan replied. "How much time is needed?" "Time...?" Tang Yuan and Yamashita looked at each other and thought for a while. "If the accessories are prepared in advance, it should be completed in three to four hours." Yamashita looked at Yuyuan and asked for his opinion. "Yes, almost this time is enough." "Accessories do you mean?" "The accessories that can input the signal into the computer through the radio, as long as it is prepared in advance, and then it only needs to be installed and wired." "So, the gangster may have reformed last night..." "It's entirely possible," Tang Yuan said. "It should be said that this is the only possibility. If it was rebuilt earlier, the maintenance personnel will find out when it is confirmed." "What about outsiders? Is it possible for outsiders to complete the transformation you just mentioned?" Hearing Kosaka's question, Yuhara and Yamashita looked at each other again. "Even outsiders, as long as they understand the structure of the AFCS used on the 'Big B' in some way, they may be able to do it." "If I tell you this structure, are you confident that you can complete it?" Kosaka asked Erping. The tall scout shook his head. "Although I understand the theory, it involves practical operation. If you don't understand the characteristics of helicopters, for example, if you have driven a helicopter before, I am afraid there is no way." "What do you think?" Kosaka looked at Yuhara. "Indeed, only those who are proficient in flying technology can do it." Tang Yuan replied helplessly. The special search team leader seemed satisfied with his answer, Kosaka nodded vigorously, looked at his watch and said: "It's been a lot of time, please hurry up and prepare for departure." ※※※ After Yuyuan and Yama went down to the Technology Main Building to get the relevant materials of "Big B", they returned to the welfare center again and went to the room where Atsuko and the others were waiting.Duzi put his arms around Gao Yan's shoulders and sat on the iron folding chair.Gao Yan seemed to have finally stopped crying, his eyes were red and swollen, Machiko sat across from them, covered his eyes with a handkerchief, and remained motionless. When Yuhara and the others walked in, Atsuko and Takahiko looked up, and Machiko moved the handkerchief slightly. "Yamashita and I are going to the helicopter soon," Yuhara said to Machiko instead of his wife and children, "We will definitely save Huita back." Machiko looked up at Yuhara, then turned her gaze to her husband. "Hui Tai...is there help?" "We will find a way," Yamashita said, "There will be a way." He took his wife's hand together with the handkerchief, and Machiko was sobbing again with his actions. Tang Yuan looked back at his wife and children, and the mother and son looked at him for help.He squatted down beside Atsuko. "Machiko is counting on you, now I can only rely on you." Atsuko didn't nod, but frowned in fear. "The helicopter is over the nuclear plant, isn't it?" she asked.She probably learned about it from the police officer. "Yeah, so we're leaving now." "Could it fall?" "It won't fall." Tang Yuan glanced at Yamashita and the others and said, "I will go down with Shan, just to prevent the plane from falling." "Is it really okay?" "Yes," Tang Yuan nodded, stroking Gao Yan's head with his right hand, "Mom, please." "Father...please save Huitai, I want to see him quickly and apologize to him..." Gao Yan began to cry again, and Tang Yuan nodded vigorously. When leaving the room and walking in the corridor, Tang Yuan couldn't help but think, should he tell his wife to evacuate as far away as possible just in case?But in front of the Yamashita couple, he couldn't bring up the topic of falling in case. When I came to the first floor of the welfare center, I found that the investigators were all gathered in front of the TV.Yuhara craned his neck and looked at the TV screen through the gap between their heads.The upper body of the female anchorwoman who hosts the evening news show appears on television. "Now we will once again break in the temporary news for everyone. At around 8:00 this morning, a large helicopter of the Self-Defense Forces was stolen from a heavy industry company in Aichi Prefecture. At present, the gangsters use remote control to drive the helicopter in Fukui County. Over the Xinyang Power Plant in Heshi, hovering about 1,000 meters away. The gangsters sent threatening letters to the power plant, the Department of Science and Technology and other units by fax, demanding that all nuclear power plants in the country be abandoned immediately. In addition , a third-grade son of the company’s technicians is currently locked up in the helicopter—”
