"What are the planes doing?" After about five minutes, Qian Yu finally couldn't help it anymore and looked out the window with a worried look on his face, even though he could clearly only see the air from his position.

"What's wrong?" Gray Plains, who was reading the manual, asked Chiha.

"Don't you feel it?" Qian Yu frowned slightly. "Airplanes have been ...... It's up and down, and it's weird at a speed......"

"It's normal to be in the turbulence," Gray Yuan said after glancing outside. "It's just an airplane after all, and it's nothing with a little ups and downs."

"Even if the speed is as constant as it is now?" Qian Yu nodded the back of his chair. "If you want to deal with turbulence normally, you shouldn't solve it by changing speeds, right?"

"This ......" Gray Yuan realized that something seemed to be wrong, and pressed his face against the window, looking in the direction of the wings behind him. You come to see? I can't see what is above the wing. ”

"Hmm," Qian Yu replied, and then unbuckled his seat belt and came to the front of Gray Plains' seat. "Hmm...... You can't see anything from this angle! ”

The lift of the aircraft uses the elevator at the tail of the aircraft, and it is really difficult to see this in the cabin.

Just then, a bell rang from behind them from the work area. "Passenger 8A calls the flight attendant."

……

In the 8A seat, where they could not see Chiba, the young man put down the JAL manual in his hand and looked at the purser who came over.

"What are you doing?" The young man asked after glancing at the person in front of him, motioning for the purser to come closer. "Are the two captains in front playing?"

"Does that explosion mean that something is wrong?" At this moment, a first-class passenger sitting in the row in front of them seemed to hear their conversation and asked. "It can't be a hole in the back of the plane, right?"

"The DC-10 airliner has three engines," Mademoiselle purser was startled and quickly explained. "Even if you lose Engine 2, you still have the ability to complete this flight, but it may be more troublesome to operate than when you have three engines."

"......" The passenger in front of him nodded and turned back, but the young man's brow was already locked. After a few moments, he unbuckled his seatbelt and motioned for Miss Purser to come with her to the work area.

"What the hell is going on?" The young man glanced around, made sure there was no one nearby, and then questioned the purser. "You should also know very well that if only the No. 2 engine blew up, it would be impossible to pitch and pitch without even turning the direction like this, but doing tricks and feet on the output of the engine."

The purser pondered nervously - she knew exactly who the person in front of her was.

This is also JAL's own person, and he is now on the JAL establishment. Before, she asked if Mu Shuli was still single, because she thought that Mu Shuli might have some unclear relationship with this little junior brother who was also from JAL.

Perhaps, he can help?

"The problem is serious right now," replied the purser after taking a deep breath. "It's not just the No. 2 engine that's the hydraulic system."

"Switch the hydraulics," the young man frowned. "This plane has three hydraulic systems, and you told me that the hydraulic system is not working?"

"None of the three sets work," the purser shook his head. "The two captains have confirmed that it is true that all three sets of hydraulics are unusable."

The ......young man fell silent for a moment before regaining his head.

"Listen to me," the young man's tone was unusually serious. "You go and tell the two captains that there is a flight instructor for a DC-10 airliner, and that he knows how to fly the plane for maneuvers without hydraulics."

When the purser left in a hurry, the young man sighed.

The unusability of the hydraulic system is definitely not comparable to a minor accident of this level of engine damage. Damaged hydraulics meant that the aircraft could not adjust its wings and tail, and normal pilots were unable to perform any lifting and steering work in such situations, and even the most basic take-off and landing was a luxury—landing required at least alignment with the runway, and in the process, the hydraulic system was required to steer the aircraft to complete the task.

This has happened before, when a commercial cargo plane in the Far East was hit by a Soviet-style shoulder-launched surface-to-air missile strike from Azerbaijan shortly after takeoff on its return from Azerbaijan. During the strike, the left wing of the aircraft was damaged, and all three hydraulic systems were leaked on the left wing, causing all hydraulic fluid to leak within minutes, and the aircraft eventually lost control.

However, the plane did not crash in the end, because in the end the pilot used his superb handling skills and rich flying experience to save the plane - as we all know, the output of multiple engines of the aircraft can be controlled separately, and if the output of the engines on both sides of the aircraft is different, the aircraft will deflect to the side with less output, so that the failure of the hydraulic system can be replaced to perform the steering task.

At the same time, the combined speed of both sides also determines the specific lift of the aircraft, and the change of lift can also adjust the flight altitude of the aircraft.

It's rudimentary, but it's at least a way to try after the complete loss of the hydraulic system – the pilots landed 20 minutes after the accident after confirming the viability of a technique that had been a guess in their own hands. In fact, the average pilot had no chance to participate in the pilot experience summary report of that incident, and only the top JAL talent like him was eligible to participate in the report meeting on foreign flights. So...... I'm afraid that he is really the only one in the entire JAL who will take the time to study how to operate this, right?

This time, perhaps in a similar situation, as a flight instructor for the DC-10, he was well aware of the plane's route. Although the DC-10 airliner has three sets of hydraulic lines with completely independent hydraulic systems to prevent damage to the hydraulic system, it ...... There are exceptions, and in order to control a series of mechanisms such as the elevator at the tail of the aircraft, the three sets of hydraulic lines of the DC-10 passenger aircraft will pass directly under the No. 2 engine near the tail of the aircraft. If Engine 2 exploded and destroyed the structure of the aircraft below, it was indeed possible to destroy all three hydraulic lines at once, as was the case with the surface-to-air missile.

Maybe this time it's more troublesome than the accident in the Far East...... After all, it was a cargo plane, and the plane also had damage to the landing gear during the landing process, resulting in a collision and damage to the cargo in the cargo plane. For this fully crewed airliner, this level of damage was enough to cause casualties.

"Captain, they agreed," said the purser, who walked up to him. "Please go to the cabin immediately."

"Got it," he said, taking a deep breath, the expression of the young man in front of him had become extremely calm. "I'll go right over."

With that, Sadaharu Takamori, a flight instructor for JAL DC-10 airliners, walked past the purser.

…………

The infrastructure of this case comes from the history that I deleted — this time from the Sioux City crash, and the 1992 incident in the Far East was elevated, which is the equivalent of the DHL cargo plane attack and the status of JAL 123.

123 and Sioux City have died too many people, so I don't want them to show up here.
