Boston is located in the northeastern United States and is the capital of Massachusetts.

When everyone arrived at Logan International Airport, NTSB investigators had been waiting at the airport for a long time. A tall, brown-haired middle-aged man stood in front of the greeting staff. After seeing Zhuo Huan, he smiled and stretched out his hand: "Long time no see, Patrick." Then he walked towards Old Joseph and stretched out his arms: "Hi, my old friend, we meet again."

The two laughed and hugged each other.

Joseph Older: "Lovens, you are responsible for this accident investigation?"

Lovens looked helpless: "I don't want to stay here either, but who did I just happened to be in Boston when the wreckage of American Airlines 4012 was discovered? This is a real bad fate, Patrick also knew that half a year ago, during the Independence Day holiday, an American Airlines Flight 2186 was urgently landed at Logan Airport. Although there were no casualties, it took me four months to find out what happened. Who would have thought that I just handed over the investigation report at the end of last month, and the next day, the wreckage of the plane was salvaged from the Atlantic Ocean."

Hearing this, Fucheng recognized the tall and strong investigator, the one he met when he came to the United States half a year ago.

Old Joseph: "You are so unfortunate. You are on a business trip for half a year and can't go back now."

Zhuo Huan: "What is the reason for that forced landing half a year ago?"

Lovens: "Oh, it's not a big deal, metal fatigue. The reason was quickly found out, but in the future, the responsible party was identified, the airline and Boeing shirked responsibility for each other, and it took a long time to do it."

Several people said while walking outside the airport.

Outside the VIP passage, two luxurious Bentleys were quietly parked on the side of the road. After getting on the bus, UAAG members went to the hotel first and put their luggage down. Soon they went downstairs and took the bus to the port.

American Airlines 4012 crashed 189 nautical miles from the coastline. NTSB directly rented a warehouse at the Boston Port as a temporary investigation headquarters. After arriving at the port, Zhuo Huan and Lovens took a boat to the salvage site, while Fu Cheng and others went to the investigation headquarters.

In mid-December, Boston was squeaking cold winds, and the temperature had already reached zero degrees. The cold and bitter sea breeze blew from Boston Bay to land. The salty, fishy and wet wind could penetrate the thickest cotton coat, almost from the soles of the feet to the heart and lungs.

The sky was getting darker, but at the port, dozens of high wattage lighting lamps were all heading towards the beach, making the bay look like daytime.

There were trembling people standing on the shore. They always gathered together, holding each other's hands tightly, and looking forward to the direction of the sea level with hope. They had red eyes and trembling bodies, but not because of the cold winter.

"After the news of the plane's wreckage was announced five days ago, many families of victims rushed to Boston from all over the place. Yesterday, a burial site was found on the seabed, and the bodies of the victims had been gradually salvaged. These people were waiting to recognize the bodies." After a pause, the young investigator whispered, "It's actually impossible to recognize them. It's been four months."

As soon as he finished speaking, a small salvage boat was turned on and drove quickly from a distance with lights.

After docking, the seafarers carried a body wrapped in white cloth off the boat and sent it to a mortal point placed on the shore. The next moment, the families of the victims gathered on the shore flocked up. However, the investigators did not lift the white cloth on the corpse and let them see the body.

During the four months at the bottom of the sea, all the victims had long been unrecognizable and almost became bones.

If you want to find your family, you can only rely on DNA testing.

The four UAAG stood on the shore, looking at the people who knew it was meaningless but ran around.

"They are not here to recognize the body, they are here to pick him up home."

The voice of the young black-haired man is long and soft in the cold sea breeze.

Lina and old Joseph turned to look at Fucheng.

The sunset slowly sank under the horizon, and on the coast, there were still salvage boats docking, and then a group of families of the victims who were crying and rushing up.

Soon, under the leadership of the investigators, they arrived at the temporary investigation headquarters.

At the same time, on the other side, Zhuo Huan and Lovens arrived at the salvage site 189 nautical miles away by speedboat.

If the Boston Port is brightly lit at this moment, the families of the victims, investigators and reporters surrounded the place. The salvage site is even more spectacular. Large marine cranes gathered on the sea. Small salvage boats are only used to salvage the remains of the victims. The real trouble for the salvage company is the giant 73 meters long and weighing 310 tons.

Airbus A390 passenger plane.

Lovens: "Patrick, if a normal plane crashes into the sea, it will be crushed by huge surface tension and turned into fragments. But it is a coincidence that the American Airlines plane was only broken into two halves underwater. One is 58 meters long and the other is 15 meters."

The person in charge of the salvage company stood aside and nodded, "Yes, although 310 tons are not heavy, the length of 58 meters is easy to cause secondary fracture during salvage. We have tried the traditional floating drum salvage method and floating hanging method before, but the effect is not very good. Mr. Lovens said that he wanted to try not to damage the wreckage of the plane."

Luo Wens looked at Zhuo Huan: "Patrick, we currently plan to use chain salvage method to salvage the aircraft. But this still cannot guarantee that the aircraft will not be damaged secondaryly during the salvage process. So I want to discuss with you first to determine if it is necessary to destroy secondary damage, which part of the aircraft has the least impact?"

Zhuo Huan received the underwater scanned picture handed over by the salvage staff.

His eyes swept through this sonar scan, and finally Zhuo Huan stretched out his hand and drew a dividing line five meters behind the cockpit, which is the first class position of the plane.

"Here, as a break point, priority is given."

Lovens immediately passed the scanned picture: "Follow this picture and continue salvage!"

Ten days before salvage, many bodies of victims were found.

However, from the twelfth day, the traces of the victims became more and more difficult to find. This is the vast Atlantic Ocean, and the remains of many victims had already drifted away with the currents, and I don’t know where to go. In the end, a total of 198 victims were found, only 76 bodies were found.

The bodies of the two pilots were not found, and only one of the crew members was found.

On December 23, after verifying the structural strength and stiffness many times, the salvage company finally salvaged the wreckage of the American Airlines 4012 aircraft that sank the seabed. The 15-meter-long tail was first salvaged, followed by the 58-meter-long first half.

It took a full 27 hours to salvage it without sleep, and finally, this behemoth appeared on the sea.

The next day, it was sent to the investigation headquarters warehouse located on the edge of the port.

When the wreckage was delivered, Fucheng was looking at the aircraft's maintenance records. He carefully checked every maintenance record of the aircraft in the past three years, from light bulb replacement to engine repairs. The A390 has been in service with American Airlines for four years, and its maintenance records have always been normal and there is no particular concern.

"Your Mocha, Fu."

Fucheng looked up and said, "Thank you, Lina."

Lina smiled and said, "Do you like cherry sauce?"

Fu Cheng was stunned: "Although I don't hate sweets, I don't have any special preferences."

Lina smiled knowingly.

Soon, the romantic and ritual French girl brought a small plate of trunk cake and placed it gently on Fucheng's table. Fucheng was a little surprised, and Lina blinked at him: "On Christmas Eve, I baked the trunk cake with my own hands. Try it, this is very common in France, and I always have to eat it on Christmas Eve."

Then Lina delivered cakes to Su Fei and Old Joseph one by one.

Everyone's cake was not covered with cherry sauce, only Zhuo Huan's cake was covered with cherry sauce.

When the bell rang at twelve o'clock, the investigation headquarters was in the office that belonged to UAAG.

Lina and Joseph, the old, immediately stopped the action in their hands: "MerryChristmas!"

The other three Chinese people who were not deeply moved by Christmas then raised their heads and said very perfunctorily: "MerryChristmas." Of course, the main person with a perfunctory attitude was Mr. Zhuo.

Old Joseph and Lina had long expected such a situation, and they had no choice but to do anything about it. None of them expected that they would spend overtime this year on Christmas.

Old Joseph said to Fucheng: "I always think that I am only 52 years old now, but I am afraid that in less than a year, I will become 82 years old. Is this an industrial injury? Fu?"

Fu Cheng smiled slightly: "You can ask Teacher Zhuo for work-related injury compensation."

Old Joseph shrank his neck: "Don't worry, I'll ask for money from Reid? I might as well think about how to study immortality, as that possibility is even greater!"

Zhuo Huan: "Ha."

Everyone laughed.

The next morning, I investigated the warehouse at the headquarters.

Lovens walked over and looked at Zhuo Huan.

Zhuo Huan was lowering his head and talking to Fucheng. Last night, Fucheng discovered that the accumulator of the plane had been repaired four times in the past three years.

Lovens: "Patrick, the people from American Airlines are here."

Zhuo Huan stopped his voice, and he turned to look at Lovens: "Well, I'll go there right away." Then he continued to say to Fucheng: "The accumulator specifications of the Airbus A390 are different from those of Mai Fei. I don't have much contact, but judging from the latest maintenance record, it's not a big problem, it should be absorbing pressure pulses..."

Fu Cheng nodded while listening: "So you mean, if there is a problem with the accumulator, you can directly look at the entire hydraulic system, look at the small ones from the big ones, and check the gaps in reverse?"

Zhuo Huan smiled, he put his hands in his pockets, said softly, "Let's go and meet the people from American Airlines together."

Fucheng was stunned, but did not object.

Halfway through, Zhuo Huan paused and said to Lovens: "By the way, please help me call Old Joseph too."

When they arrived at the conference room on the second floor, Fucheng followed Zhuo Huan and entered the door together.

As soon as they entered the door, the American Airlines staff immediately stood up and said hello to them. Soon, everyone sat down. Zhuo Huan was too lazy to talk on such occasions, and Fucheng had an inexplicable illusion: Mr. Zhuo brought him here, was it because he was specifically to deal with these American Airlines staff who were crazy about finding topics?

As he was talking, the door to the conference room was opened again.

Lovens walked in first, and the two American Airlines staff stood up and were about to speak, but behind Lovens, Old Joseph also entered the conference room.

Almost in an instant, one of the staff members stood up straight.

"Mr. Joseph!"

Old Joseph was stunned and looked up. He smiled and said, "It's you, I remember you are... Joey?"

The staff member hurried over and half bowed and stretched out his hand: "Long time no see, are you okay?"

Old Joseph patted his hand and laughed: "It's not long. I followed the US Airlines case two years ago. When I returned to the US Airlines headquarters, you forgot it? Oh, maybe you were not here at that time!"

Old Joseph was kind and humorous. Gradually, the staff member named Joey relaxed his serious expression and laughed.

Looking at this scene, Fucheng frowned and noticed a strange sense of dissonance. He thought about it and turned his head to look at Zhuo Huan, but his eyes were stunned the next moment when it touched the other party. Uncle Zhuo leaned on the sofa, chewing gum, and lazily looked down at his phone.

Seeing Fu Cheng's gaze, Mr. Zhuo raised his eyelids and looked at him.

After thinking about it, he took out a piece of chewing gum from his pocket and stuffed it into Fucheng's hand.

Fucheng: "..."

Seeing that Fu Cheng had not looked away, Mr. Zhuo raised his eyebrows, pulled out his coat pocket, and lifted it for Fu Cheng to show it.

Zhuo Huan: "It's really gone."

Fucheng: "..."

Who wants gum!!!

The author has something to say:

Zhuo Anxi: I don’t understand what young people are thinking now, and I always want to get something for nothing. Giving a piece of chewing gum is not enough. I still want two pieces? I’m shameless.
