China Eastern Airlines flight MU5735 with 132 people on board lost contact and crashed over Teng County, Wuzhou, Guangxi. An industry insider in mainland China said that flight accidents in the cruising state are extremely rare in aviation history. The plane had completely disintegrated, and a loud explosion had been heard before, according to villager witnesses.
Data from flight data service company Frequent Flyer shows that flight MU5735 had been sailing at an altitude of about 8,869 meters after takeoff, when it suddenly descended and was lost.
According to the data from “Frequent flyer”, flight MU5735 took off from Kunming Airport at 1:15 p.m. and was cruising at an altitude of about 8,869 meters until 2:19 p.m., when the plane suddenly dropped from the cruising altitude while flying at a speed of 845 kilometers per hour, and then lost contact with the ground two minutes later.
Wang Yanan, editor-in-chief of Aviation Knowledge magazine, told the Global Times that there are many claims and it is difficult to make a judgment on the cause of the accident based on the available information. It is possible that the aircraft lost power at cruising altitude and the pilot was unable to control the aircraft itself, causing the aircraft to enter into a high-speed descent, thus causing the accident, which means there was a very serious technical failure.
However, Wang Yanan stressed that it is an extremely abnormal phenomenon if the plane suddenly fell. As for the specific cause of the accident, the black box is to be found to make a judgment.
According to the analysis of aviation professionals, the Boeing 737 is a twin-engine aircraft, even if all the two engines failed at the same time, it is impossible to fall at this speed, the aircraft can also fly a distance by gliding.
According to the villagers involved in the rescue of the scene, the aircraft involved in the accident had completely disintegrated, and a huge explosion had been heard before. Against the villagers’ corroboration and data analysis, the probability indicates that the plane had disintegrated in the air before landing and finally touched the ground in free fall, and the fire at the scene also aptly illustrates this point.
It should be noted that the Boeing 737-800 aircraft is only 6 years old, and the model is not the Boeing 737MAX, which has been suspended by the Civil Aviation Administration of the mainland after 2 crashes in a row with Lion Air Indonesia and Sophia Airlines. The Boeing 737-800 belongs to the third generation Boeing 737, a narrow-body mainline airliner that is currently equipped in large numbers by Chinese domestic and foreign airlines, and has been used more frequently after the Boeing 737MAX was grounded.
According to mainland Chinese industry insiders, flight accidents in cruise conditions are extremely rare in aviation history. A sudden and rapid fall from an altitude of 8,869 meters in a short period of time. Many aviation industry insiders say that it has completely exceeded professional knowledge.
Some analysts believe that what could cause the airplane to disintegrate in the air is not possible except for external energy and internal energy damage to the structure, external is well understood, but in such a safe place as mainland China, it can be completely ruled out, internal damage is most likely to come from the baggage or other aspects, but in the mainland Chinese domestic airports known for strict, can also be basically ruled out.
Finally, the only possible factor is the aircraft cabin airtight structure damage, resulting in pressurization rupture, of course, for the most direct cause, but also need to judge by looking for aircraft wreckage, waiting for specific official news.
The latest rescue information from Wuzhou, Guangxi, shows that the wreckage and debris of the airliner have been found, but the remains of the victims have not been found.
It was previously reported that China Eastern Airlines, which is under the pressure of tens of billions of losses due to the ongoing pandemic situation, has said that it will reduce operating pressure by strictly controlling “maintenance costs and reducing costs”. It’s unknown if this accident is related to this, and a further official investigation is needed. Source
