Seattle, Roger 318 temporary investigation headquarters.

In the empty and spacious factory, a silver-white Maifei F485 was parked in the center of the factory. Dozens of researchers wearing laboratory suits kept walking up and down to debug the aircraft's basic data. When all the variable elements were ready, Lovens, who was standing in the second floor laboratory, made a gesture of ok to the person below through the floor-to-ceiling window.

Old Joseph, who was standing on the first floor, also returned to him, and then his voice calmed down: "Start the experiment."

With a humming sound, the plane started, and the first experiment of the Maifei f485 automatic cruise system officially began.

In the first three days of the actual aircraft experiment, the investigation headquarters did not actually conduct flight experiments, but conducted "semi-" real aircraft experiments. They simulated the relevant data on the day of the crash of Roger 318, and observed the response measures of the aircraft's autonomous driving system.

Lovens published the results of this "semi-" real-aircraft experiment at a weekly meeting: "According to the specific meteorological data provided by the Russian Meteorological Administration, we conducted a total of twenty-one real-aircraft experiments in the laboratory. The experimental results showed that 19 times, the Maifei F485's autonomous driving system responded to small ocean front waves 30 nautical miles away, and 17 times, the aircraft chose to deviate from a certain distance when the route allowed."

Old Joseph continued his words: "This is an extremely smart plane, and we all know that it will even automatically contact the tower and send yaw permit codes."

Deputy Director Andrew looked at an investigator at NTSB next to him. The latter nodded and said to him: "This kind of yaw code is too short because the yaw distance is too short. According to the latest Faa air traffic control agreement, there is no need to obtain a manual air traffic control permission at all. The computer directly recognizes the yaw permission."

Lovens concluded: "So, based on the simple experimental results, Roger 318 took active right yaw operation because of the distant frontal wave. So far, everything was a reasonable operation of the computer."

Zhuo Huan pondered for a moment: "When will the actual machine experiment be carried out?"

Joseph Old Joseph: "Four days later, according to the US Marine Meteorological Service, four days later, at 2 pm, a frontal wave occurred in the northeast Pacific basin, western Guadalupe Island. The relevant weather was very close to the Rogue 318 air crash five years ago. At that time, we will fly the Maifei F485 and conduct a fully simulated test flight experiment."

Four days later, San Francisco International Airport.

A brand new Mai Fei F485 parked steadily at the starting point of the runway, and the sun shone on it like a sharp sword. The warm sunlight in winter afternoon shines into the cockpit through the dark windshield.

Fucheng sat in the driver's seat, beside him, in the passenger seat, for the first time.

That was a brown-haired American pilot.

This test flight test is too important and no mistake is allowed, because the ocean climate is unpredictable. No one can guarantee that similar frontal waves will appear again. When the US Weather Service detected this frontal wave that was extremely similar to Roger 318, everyone felt that this might be fate and destined by God.

Similar locations, near the North Pacific Ocean.

In a similar climate, small ocean frontal waves formed by collision of two air masses.

If Rogue found 318 nights for one month, they could not find such a great opportunity.

Perhaps in the dark, the 298 souls who were silent at the bottom of the sea for five years also shouted.

Countless people all over the world work together, and they are heading towards that truth.

So there is no mistake.

Fucheng: "Prepare for inspection before taking off."

The deputy captain nodded and turned on the plane's safety manual: "Start pre-take-off check. The navigation lights are turned on, confirm that inertial navigation is turned on..."

After five minutes of boring and repeated safety inspections, the voices of Fucheng and the deputy captain kept ringing in the quiet cockpit.

The deputy captain is named Cad Worth, and is a very outstanding US Air Force pilot and an experienced test pilot.

Fucheng and Kade had a very deep understanding of Maifei f485, but they did not slackew. They carefully checked each step, even if these steps were like adults fiddling with children's toys to them, they did not look down on them.

After the examination, the two looked at each other.

Fucheng Zhending spoke in an orderly manner: "Confirm the takeoff."

The plane started to accelerate on the runway.

Its speed was getting faster and faster. Finally, it buzzed and left the earth smoothly and drove towards the sky. After turning a 180° bend in the air, it turned around and headed westward towards the Pacific basin.

At the same time, hundreds of investigators and labs in the airport laboratory did not waste time.

Lovens: "Real-time monitoring of all flight data."

Joseph Older: "Focus on data related to the aircraft's automatic cruise system."

Zhuo Huan stood in front of the podium, he raised his head and looked at the small green dot on the radar map. Five minutes later, he pressed the communication button calmly.

In the cockpit, the man's cold and calm voice sounded.

“Cruise altitude.”

Fu Cheng tightly held the rudder in his hand, and he looked at the dashboard: "29,000 feet."

Zhuo Huan: "Full turn on the automatic cruise system."

Fucheng: "The automatic cruise system has been turned on."

Zhuo Huan: "You are approaching that frontal wave."

Fucheng: "Yes."

Zhuo Huan: "There are 35 nautical miles left."

After the words fell, there was a long silence.

In the cockpit of Maifei F485, both pilots held their breath and looked at the meteorological map detected on the aircraft's meteorological instrument panel. They were getting closer and closer.

There are still 34 nautical miles.

33 nautical miles.

32 nautical miles...

It should be 30 nautical miles, but it did not wait 30 nautical miles. When the plane was 31 nautical miles away from the front wave, Fucheng's eyes sterned and he quickly turned on the communicator: "The aircraft's autonomous driving system has begun to turn automatically."

The next moment, Zhuo Huan calmly said: "Wait for three minutes."

Fucheng and Kade: "Yes."

Three minutes was when the two deputy captains on Roger 318 ignored the time when the plane turned automatically to the right. Because of abdominal pain, the deputy captain David didn't care about looking at the dashboard; because of the sudden abdominal pain of his companion, the other deputy captain William was unable to find the plane turning at the first time. And they finally found that the plane was turning and decided to operate, and a total of 2 minutes and 57 seconds passed.

Time passed minute by minute, and when the plane had quietly turned a 35° turn right, Cade turned his head and looked at Fucheng: "Discover the turn."

Fucheng immediately reached out: "Switch off the aircraft's automatic cruise system."

"Pu"

With a crisp sound, Fucheng and Kade were staring at the aircraft dashboard.

This second became extremely long in their eyes.

Fucheng seemed to hear his heart thumping and beating slowly in his chest. He didn't know what he wanted to see, and he easily turned off the automatic cruise system? Then the experiment was over. He and Cade were not at all dangerous, and they could easily take over the plane.

However, the automatic cruise system cannot be turned off, which is what happened to Roger 318, Qi Zhifeng, David and William.

They should choose to turn off the automatic cruise system as soon as possible.

This is common sense, a basic common sense. The most basic common sense that any pilot should know even if he has not graduated from the Flight Academy.

Can the automatic cruise system be simply turned off? Or is it really malfunctioning?

A second later, Zhuo Huan looked at the data transmitted by the plane. At the same time, Fucheng's calm voice came from the communication sound: "Confirm to turn off the automatic cruise system and start manual driving."

Closed his eyes, Zhuo Huan sighed softly.

On March 16, 2022, the test flight experiment ended.

Zhuo Huan glanced at hundreds of investigators in the conference room and said: "Experimental evidence has confirmed that Roger 318 was confirmed on the day of crashing. Because he encountered the ocean front wave, the aircraft's autonomous driving system directly chose to sail to the right."

Deputy Director Andrew nodded slightly, and said, "This should be the direct cause of the air crash."

Lovens: "During the test flight, the pilot easily turned off the automatic cruise system, so the design reasons of the aircraft were ruled out. Then there are only two possibilities left. The first is the pilot's handling error. They have the opportunity to save the aircraft. Before the aircraft completely loses control, they have about 30 seconds to save it, while turning off the autonomous driving system only takes 1 second. The second possibility is the plane parts failure."

Zhuo Huan looked at Lawrence: "Have you found the other two black boxes?"

Lawrence: "I have retrieved a black box and now I've sent it to Mai Fei's headquarters in Los Angeles to analyze the data."

Zhuo Huan: "When can I catch the plane?"

Lawrence's face changed slightly. He silently said helplessly: "Give me another month and a half."

Zhuo Huan looked at him steadily.

Lawrence pursed his lips and sighed, "Reid, this is not something that can be solved by working overtime or spending money. I have arranged for someone to customize a giant tank that can accommodate a plane. If you want a broken plane, I can fish it up in seven days. But if you want a complete Rogge 318... give me a month and a half."

Zhuo Huan glanced at him deeply and nodded.

Lawrence breathed a sigh of relief.

Zhuo Huan looked at Old Joseph: "Where is Su Fei?"

Old Joseph smiled and said, "Of course he followed him to Los Angeles. By the way, let me tell you something before flying."

"Um?"

"Reid, seven days, he will definitely bring you the black box and the data inside it intact."

***

Los Angeles International Airport.

The investigators at ntsb walked in front with a heavy box. The punk teenagers followed them and came to the underground parking lot together.

The staff of Maifei Laboratory have been waiting there for a long time.

Su Fei, the person who came to pick them up, actually knew him. He saw the blonde Mai Fei, director of the public relations department, and raised his eyebrows.

When Johnny saw them, he immediately walked over with a smile on his face: "Please come with me, Mai Fei's laboratory is ready, I'll wait for you to go." As he said that, he looked down at Su Fei and smiled: "Long time no see, Mr. Su."

"It's not long, it's more than half a year?" Su Fei thought for a while: "Last time we came here, it seems that you were not the one who came to pick us up."

Johnny smiled slightly: "Last time I was on a business trip in Europe, and this time I was in Los Angeles, so I'm here."

Su Fei thought for a moment, but felt that there was no problem. He looked at the box held by the NTSB investigator, thought about the black box inside, and remembered the test flight test that Fucheng went to San Francisco two days ago.

The punk boy muttered, "Are you really going to find out the truth?"

Just like fate.

The test flight experiment was successfully carried out with the right time, place and people. It also achieved very satisfactory results.

It's like fate.

Lawrence's salvage company found one of the two remaining black boxes in the deep sea silt 15 nautical miles away from the plane's wreckage. This black box was even more complete than the first one found. Su Fei knew at the first glance that at most seven days, he would be able to parse the data in this black box, and it would not even take less than seven days.

Moreover, this is installed at the rear of the aircraft, the main black box that records almost all the control data of the aircraft.
Chapter completed!
