The Boeing 737800 crashed into a field in Wuzhou. The joint investigation of the Chinese and US experts of the incident. Chinese President Xi Jinping said he was shocked

Forty seconds before the crash, the China Eastern Airlines Boeing 737800 tried with all its might to avoid the impact by regaining altitude. It wasn’t enough. Immediately afterwards, the plane carrying 132 people (123 passengers and 9 crew) crashed into the bamboo and tree hills at almost 700 kilometers per hour and broke up south of Wuzhou at 14.22 and 45 seconds local time (7.22 in Italy).

This is one of the details that the Chinese and US investigators need to unravel in order to understand what caused one of the largest catastrophes in the Asian giant’s skies and the first since 2010.

Chinese President Xi Jinping said he was shocked by the incident and called for making every possible effort to organize search and rescue operations, deal with the aftermath, step up investigations into potential civil aviation security risks and ensure the absolute safety of operations to guarantee. China Eastern now the country’s main airline and the world’s sixthlargest scheduled airliner has decided to ground the other 101 Boeing 737800s in the fleet to learn more about the tragedy.

The Boeing 737800 takes off at 13:11 from Kunming to Guangzhou where expected at 15:05. According to the National Meteorological Center at 14.15 at the scene of the accident, the weather is cloudy, but not raining, the temperature is 30 degrees Celsius, the wind is blowing at 19 kilometers per hour, and visibility is 16 kilometers. The aircraft takes off at 2:16 p.m. at a cruising altitude of 8,870 meters and 843 kilometers per hour. But at 14.20 and 59 seconds, the raw data collected by Flightradar24 shows the plane lost over 600 meters in sixteen seconds. The fall continues, steeper and steeper, so much so that the Boeing falls at almost 109 meters per second (to 2,263 meters). Then, gaining altitude for another ten seconds, it reaches 2,621, but then points its nose at the ground again, where it crashes a few seconds later.

what could have happened Insiders urge not to jump to conclusions without evidence. Crucial information can only be provided by the black boxes (one that records the pilots’ audio, the other that stores all flight parameters). On the basis of the values ​​​​collected and the crossing with a video showing the last seconds of the Chinese jet two Boeing 737 pilots consulted by the courier explain that the explanations usually boil down to two in order to approach these variometric speeds go: o a serious technical problem or intentional gesture by someone in the cockpit. The plane does not actually appear to be spiraling as it descends vertically.

In recent years, China has made many strides in aviation safety: According to the Aviation Safety Network, the last fatal accident dates back to 2010, when a Henan Airlines Embraer E190 with 96 people on board crashed, killing 44 people.

China Eastern is one of the most important companies in China and very present in Europe before Covid. Data provided by the Cirium platform shows that the crashed aircraft had been operational since June 22, 2015, clocking up 17,708 hours of operation and 8,734 takeoffs and landings.

The Boeing 737800 not to be confused with its successor, the 737 Max is one of the two most popular aircraft for short and mediumhaul flights (there are over 4,200 worldwide). The other model and direct competitor is the Airbus A320. During this period, 22% of flights will be operated with an A320, 19% with a Boeing 737800. Disasters while driving are also considered rare occurrences, as they are usually controlled on autopilot. Boeing estimates that from 2011 to 2020 only 13% of accidents, or less than one in eight, occurred during this phase.
