Before the crash, I called China Eastern Airlines several times and failed to reply. How serious is the damage of this plane? What is the cause of the crash of China Eastern Airlines MU5735? What happened before the crash?

1. As for the first case, when China Eastern Airlines just had an accident, all kinds of people came out and shouted, all of which were losses. Comprehensive news, the domestic crash has ruled out the possibility of shooting down.

2. Hit a bird. The passenger plane began to descend at an altitude of about 9000 meters. At this altitude, there are very few birds that can fly, and the probability is very, very low. If you hit a bird, there are two situations. First, it hits the wing and the engine side. If this is the case, the driver had enough time to point out the problem, make a report and ask for help, but he didn't report it. Second, the bird directly crashed into the cockpit, causing two pilots to be injured, making them unconscious or unable to control the plane, thus the plane was out of control, but the probability of making two pilots unconscious at the same time was very, very small.

3. The probability of human factors is very small. First of all, the captain is the second generation, and his business ability is low-key and solid, while the co-pilot is a five-star captain with 40 years of flying experience. Many of his apprentices are powerful people in the industry, so there should be no problem in manpower control.

The plane is probably out of order. First of all, Boeing 737 has not broken down twice. The latest one was the crash of a 737MAX8 plane from Jakarta to Bangka Penang in lion air, Indonesia on 20 18. When analyzing the cause of the crash, the investigators said that the aircraft (mcas, a mobile augmentation system to prevent stall) failed, and the system repeatedly pushed the aircraft nose down.

5. The weather. Judging from the satellite cloud picture, the weather conditions at that time were not bad, so the possibility of extreme weather was relatively small. But it is also possible that the weather is unpredictable and thunderstorms suddenly appear. It is not impossible for lightning to hit the plane and cause various instruments to fail.

So to sum up, the possibility of aircraft failure is relatively high, and extreme weather is also possible. Of course, it may also be the superposition of multiple factors, leading to tragedy. In the end, it is necessary to find the black box as soon as possible in order to investigate the final reason.

The black box has just been found. The cause of the crash and what happened on the plane at that time will not be known until the black box is decrypted. Maybe it's the mechanical failure of the plane, or maybe it's the weather. Only by decrypting the black box can we know what happened on the plane. Now the recorded black box is being decrypted, and I believe the cause of the plane crash will be announced soon.

What are the functions of the "black box" hidden on the plane when the China Eastern Airlines passenger plane crashed? Why is it so important?

As an important flight data recorder, black box records a lot of important information in the flight process and becomes the key to solve the cause of flight accidents. One of the two flight data recorders was found in the surface soil about 20 meters southeast of the main impact point at the accident site. Next, investigators will continue to search for another flight data recorder.

The official name of the black box is "Flight Information Recording System". A complete black box system is mainly composed of cockpit voice recorder (CVR) and flight data recorder (FDR), which are combined into one. In other words, an airplane has two black boxes with different functions. The cockpit call recorder can record all kinds of calls on the plane. It has multiple sets of audio tracks, which can record the dialogue between pilots and ground control tower, the dialogue between pilots, the broadcasting of pilots and flight attendants to passengers, all kinds of abnormal sounds and all kinds of sounds in the cockpit, and can help investigators analyze the cause of the accident.

The flight data recorder can record all kinds of flight data, including more than 200 kinds of data such as flight attitude and flight trajectory, and there are various sensors on the plane. Flight data recorder, like recorder, must record every detail and provide important data support for air crash analysis.

The black box is not big, only a few kilograms, and the size is only one-third of that of an ordinary drawer. Modern black boxes are resistant to high temperature and high pressure, and can withstand the maximum overload of 1 1ms of 3400G and the high temperature of 1 100/h. After soaking in seawater for several months, the integrity of internal data can still be guaranteed. During World War II, aviation flight recorders began to be loaded on military aircraft. After the war, this technology was applied to civil aircraft, which is the prototype of black box. In modern times, this musical instrument is packaged in a black box, which is the origin of its name.

Black boxes are usually installed at the tail of aircraft. This position is usually the least damaged in flight accidents. A black box is generally about 50cm long, 20cm wide and weighs 20-30kg.

The crash site of China Eastern Airlines passenger plane was in the forest of tengxian, Wuzhou City. The scenery in the mountains is hard to find. After two days and two nights of carpet search by various forces, I finally found some black boxes. Since the black box records such important information, according to the common people, it should be very hard and strong, and it should be easy to find, just like GPS. But it took two days and two nights to find some of them after searching in many ways.

In the field of international aviation, black box has always been considered as the key to find out the cause of the accident. Under normal circumstances, the black box can continuously send signals to the outside world for up to 30 days. Now, the ultimate throwable black box has been developed. This black box has the function of launching before the crash, and can withstand a certain impact and catch fire after leaving the plane. In addition, it has a floating function, and also has a built-in radio fixed beacon and Beidou satellite positioning beacon, which can accurately locate search and rescue in the first time, greatly improving the efficiency of accident search and rescue and shortening the time of accident investigation.

Why did the China Eastern Airlines crash only confirm the identity of 120 people? Are the other 12 people still alive?

Although everyone has been waiting for the miracle to happen, it's a pity that we didn't see it.

On March 26th, a press conference was held in emergency headquarters, the country where the 3.2 1 "China Eastern Airlines MU5735 plane crashed. At the meeting, it was clearly informed that all the 23 passengers and 9 crew members on the 3.2 1" China Eastern Airlines MU5735 flight had been killed.

Although this result is hard for everyone to accept, it is a reality, and we can only mourn for many victims here. But at present, the identities of 132 victims have not been fully confirmed. As of 26th, only 120 victims have been confirmed. After six days of search and rescue work, the criminal technology department of the public security organ dispatched 220 people to form 29 exploration groups to carry out on-site investigation, search and rescue and inspection, and confirmed the identity of 120 people, including 1 14 passengers and 6 crew members. The identity of these victims can be confirmed by DNA analysis of the wreckage and human tissues collected at the scene, and then comparison.

Then why are there 12 people whose identities cannot be confirmed? This 12 person probably should be at the bottom of the nose, possibly inserted deep underground, so their remains and related tissues have not been found yet, so it is impossible to confirm them specifically. However, with the deepening of the on-site search and rescue work, some wrecks and remains will eventually be found, and it is only a matter of time before the identity of this 12 person is confirmed.

For this 12 unidentified passenger and crew, although everyone hopes that they can miraculously survive, MU5735 fell from a height of more than 8,000 meters and directly drilled into the ground for more than ten or twenty meters. Even the engine and other parts are broken, not to mention the human body. Therefore, although the identity of 12 people has not been confirmed, there is basically no possibility of survival, but it takes time to confirm.

The next step is to appease family members and start related compensation work. As for how much compensation each victim can get in the end, there is no relevant plan at present, and the top priority at present is rescue. In addition, who will bear the final compensation? This can only be concluded after the identification of the plane accident. At present, the cause of the plane crash is still inconclusive, whether it is the fault of the plane, the operational error of the crew, or other emergencies.

Although one of the black boxes has been found at present, and this black box is an engine room recording black box, the analysis time will be longer because of serious damage, and it is estimated that it will take more than half a month to get the final analysis result. Moreover, only one recording black box can not completely restore the process of the plane accident, and it needs to cooperate with the second black box, that is, the flight recorder, in order to get a more accurate judgment. But the second black box has not been found, and search and rescue personnel are searching.

If the second black box can be found in the future and analyzed with the recording black box, it is possible to get the specific cause of the plane crash. However, even if the second black box is found, it is impossible to reach a final conclusion in a short time. After reading the data from these black boxes, the data will be analyzed and compared according to the actual situation in all aspects, and finally the final accident report will be formed, and then the responsibilities of all parties will be determined and compensation will be made according to the accident report.

Before the crash of China Eastern Airlines passenger plane, many calls were made, but there was no reply. How is the investigation of this matter going now?

China Eastern Airlines MU5735 passenger plane was repeatedly called by air traffic controllers and other captains before it crashed, and finally fell vertically from a height of 10,000 meters into the depths of the mountains near Mo _ Village, Nanzhen Town, tengxian City, Wuzhou City, Guangxi Province, attracting the attention of the whole country! China Eastern Airlines MU5735 can be said to be an unprecedented air crash! After all, China Eastern Airlines MU5735 fell vertically from a height of 10,000 meters, and there is no precedent in the world! Because the air crash has attracted much attention, the relevant departments immediately set up an investigation working group after receiving the news of the crash of China Eastern Airlines passenger plane MU5735, which is responsible for the investigation and follow-up support of the MU5735 catastrophic air crash!

After the fire rescue workers entered the scene of the plane crash, the accident investigation team also began to investigate! The investigation began to sort out and study the maintenance data of China Eastern Airlines MU5735 before take-off, and initially determined that China Eastern Airlines MU5735 was seaworthy after take-off, and the whole flight was normal before the accident, regardless of the weather or the state of the aircraft! Before the accident, the captain and the air traffic controller could maintain normal contact, indicating that the accident occurred in about two minutes! The key to the investigation of the MU5735 accident lies in what happened in this "two minutes of death".

black box

After entering the incident, search and rescue personnel searched and rescued day and night. After unremitting efforts, they finally found the black box of MU5735 recording voice! Now this black box has been repaired and decoded by Beijing and other relevant departments. It can be said that the progress of the investigation will advance by leaps and bounds if the black box is found! There is still a black box that has not been found. I believe that after finding another black box, combined with some data of the wreckage of MU5735 and the information of the two black boxes has been completely cracked, the "two minutes of death" can finally be restored. What happened?

think

The MU5735 air crash has attracted much attention. I believe that the investigation of this matter will be gradually promoted under strict circumstances! I finally figured out the truth about MU5735 crash!

Before the crash of China Eastern Airlines passenger plane, it called many times and did not reply. I believe that the captain was passive at that time!

Before the crash, I called China Eastern Airlines several times and failed to reply. How serious is the damage of this plane?

Before the crash, I called China Eastern Airlines several times and failed to reply. How serious is the damage of this plane? The plane could not be completely inserted into the land, so it had to hit a big hole, and then its body was compressed by gravity, especially at the front end, and the people in the plane were crushed to death by gravity. With the fire burning for a few seconds, it will soon burn out. Except for some large pieces of metal left on the surface, other objects will burn to ashes and become black smoke, which will be scattered around with the rising smoke. As for the debris of the aircraft wreckage found, it was ejected by the impact force when it fell. Generally, there is a certain distance from the landing point so as not to be melted. China Eastern Airlines Flight 737 was like a silver stick that went straight into the ground. The place where it crashed was the soft soil between two mountains. It is estimated that it exploded after falling into the soil, so we can only find the remains of the victims at the origin of the explosion disintegration, because it takes a long time to dig deeply and carefully! We must find the black box as soon as possible to understand the cause of the plane crash! May the deceased rest in peace and have a good journey!

We can't find the fuselage because the fuselage hangs directly at high speed, and people and other things are pushed to the tail of the fuselage by the relativity of speed. When the fuselage directly hits the ground, it will produce the relativity of self-weight and speed and drill into the ground. This is the first wave. Based on the relativity principle of self-weight and speed of instantaneous impact, all the weight of the fuselage and tail will once again produce a second wave of closed extrusion from top to bottom, and then the fuel consumed at last and the spark generated by impact will explode instantly. Starting from this thinking logic, almost everyone will be pushed. If it doesn't disintegrate vertically in mid-air or explode due to impact, then the lucky one may still be possible! According to the online video, the plane fell almost vertically and then exploded. Falling at an altitude of more than 8,000 meters, the speed is as high as several hundred kilometers. In addition, the fuel on the plane exploded, and the central temperature should have reached the gasification level.
