Chapter 1799: Boeing 747

Time went back five hours.
Island Capital Airport.
"Attention, all passengers, flight 8119 is about to take off. Please follow the order and board the plane from Channel 3."
At this time, it was late at night, and there were not many people in the airport. However, for this busy route, no matter what time it was, it could be full of people, especially the wide-body Boeing that performed the flight mission. The 747 passenger plane is one of the largest passenger planes in human history. It can carry more than 500 people!
Until the appearance of Airbus's A380 passenger plane, it has always been a giant in the civil aviation market, with the largest passenger record lasting 37 years.
Now, more than 500 passengers have entered the airliner in an orderly manner. Inside the airliner, the first thing many people do when sitting on their seats is to put on blindfolds and sleep on the airliner. For them, this is not For a long time, they only need to sleep before they reach their destination.
The banker Yamamoto was sitting by the window. He didn't fall asleep when everyone else was asleep. He turned on his laptop. This kind of computer produced by Hanxin Technology is expensive and only the richest can do it. Owning it, but for bankers, they don’t care about funds. What they care about is efficiency.
They have been very busy recently. The Minister of Finance of the island country has already gone to the Eagle Country. It is said that the island country’s currency will rise. What good is this for the island country? What can the banking sector do to make profits from it? This is something that Yamamoto has been studying recently. At this time, he put his fingers on the keyboard and kept tapping, writing a report.
Just after the passengers in the back got on the plane, the crew in the front cabin was also making final preparations.
In the position of the captain, the pilot is sitting. After this flight, he can be promoted to captain. Therefore, the captain asked him to feel the flight in the captain's position in advance, and the captain Gao Bin Sat on his right.
"Connect the autopilot, we have flown this route many times." Gao Bin said.
Although it was only in the mid-1980s, the development of computers has already been rapid. This type of large passenger aircraft is equipped with autopilot. As long as you fly it once before, you can now use the data to control the aircraft to fly by itself. , So you can make the pilot easier.
In addition to manual control during take-off and landing, the crew is actually quite comfortable in normal flight.
Now, the pilot skillfully moved the switches, all four engines started normally, and the huge passenger plane slid onto the runway, and then left the runway in the dark and flew into the sky.
"At a height of 7,300 meters, we will cross the sky over the island country." The captain said, his eyes glanced out and he could see that the ground below was still brightly lit. This is the island country, prosperous. The island country, their country is so prosperous, even at night, you can see such a beautiful scene.
According to Gao Bin's instructions, the pilot turned a turn and sailed westward, crossing the large tracts of land in the island country. They did not know that the danger was coming little by little.
"Boom, boom." A few clear noises, this noise in the cabin sounded so real.
"What's going on?" Those who are sleeping do not know, but the flight attendants in the cabin are still awake, and the voices they hear come from the tail.
The stewardess glanced back, and suddenly, from behind, there was a terrible air current, like a huge attraction, sucking her in that direction!
"Oh, no!" The flight attendant's voice was loud, and her hand grabbed the armrest on the side seat and shouted loudly: "The cabin is depressurized!"
In the training, they have received these trainings.
The plane is flying at high altitude. Generally speaking, every 12 meters higher, the air pressure will drop by one millimeter of mercury. At the current altitude, the air pressure outside is only 0.2 of the normal atmospheric pressure!
Once there is a leak in the cabin, then, the inside of the cabin is pressurized with normal atmospheric pressure, and the outside is only 0.2, then the air in the cabin will fly outwards gurgling, and this is the feeling now.
As the air in the cabin continues to pour out, the pressure in the cabin will become lower and lower. In this case, people will be unconscious due to lack of oxygen.
If it is an ordinary passenger, it is not a big problem if the captain is unconscious, but if the captains are also unconscious, the plane will be completely hopeless! At the same time, the outside temperature is also very low, or to say, it is around minus fifty degrees. The cabin will soon become cold!
"Oh, it!" Almost at the same time, Captain Gao Bin in front also reacted. He immediately pulled the emergency handle on the side, and then, an oxygen mask fell over each passenger's seat.
"Please wear an oxygen mask!" The stewardess exhausted all her strength before she got into the seat on the side, fixed herself, and started broadcasting to everyone. At this time, things were constantly flying on the plane. Falling towards the back.
The passengers kept exclaiming, and then they saw the oxygen mask in front of them and put them on in a hurry.
"Disconnect the autopilot and control it manually!" Gao Bin shouted, and the mechanic behind also shouted: "The hydraulic pressure is dropping!"
"Don't be afraid, we have four hydraulic systems," the captain said.
"For three of them, the hydraulic pressure is dropping!" Of course the mechanic knew it, but his voice was still full of horror.
The four hydraulic systems are all independent. Now, all three of them are declining, which means that three of them are malfunctioning, and only the last one is left. Will it work?
"We are descending!" the pilot shouted. Almost at the same time he shouted, he was already using his best to hold the control panel in front of him into his arms.
He wanted to pull up the plane, but the plane did not pull up as expected. The plane continued to descend and descend. Moreover, it had already dropped in altitude and its speed became faster and faster. If this continues, they will definitely Crashed.
"The fault is found, it's in the luggage compartment. The hydraulic tubing there has leaked and is leaking hydraulic oil! Damn Boeing!" At this time, the mechanic's curse was for a reason.
In a previous flight, when the Boeing 747 landed, because of improper control by the captain, the tail was scratched and the semi-circular rear cover was damaged. Of course, such damage could not be scrapped, so they asked Boeing to repair it.
According to normal practice, they should replace the entire back cover, but Boeing found it troublesome and did not do that, but replaced a few of them. Moreover, no one knows now that Boeing did not take it seriously, and even failed to use two rows of rivets as required when fixing it. Only one row of rivets was used.
At the beginning, maybe it was all right. After such a long flight, metal fatigue appeared there. It's definitely going to happen, it just depends on who is on it. Right now, it happened to be their crew. Just now, the place where the rivet was fixed broke, and there was a big hole immediately behind, so the pressurized air in the cabin Gushing out instantly, decompression occurred.
Moreover, the back cover flew out after it was broken, and a large piece of vertical tail was torn off, and the hydraulic circuit was broken at the same time!
