Search groups are nonetheless searching for the flight’s black box that would assist decide the precise cause for the crash, after evaluation of its knowledge.
However specialists have already pointed to the bizarre nature of the airplane’s final obtainable flight knowledge. The airplane was at a point in its journey when pilots often prep for touchdown, nevertheless it as a substitute plunged immediately down from 29,000ft in lower than two minutes.
John Cox, an aviation security advisor and a former pilot, was quoted as saying by Bloomberg that it was “onerous to get the airplane to do that”.
The Boeing 737-800 has a wonderful security report and has been deployed around the globe because the Nineteen Nineties, a part of the Subsequent Era period. It preceded the 737 Max, which was grounded globally after two lethal crashes in Indonesia and Ethiopia.
Investigators at the moment are eager to know what sets this crash apart from earlier accidents. The investigators will take a look at the climate the airplane encountered, any misery calls made by the pilots in the course of the flight or whether or not there was any technical failure, in line with Bloomberg.

Jeff Guzzetti, the previous accident investigation chief of the US’s Federal Aviation Administration, mentioned the crash was “very odd”.
Specialists mentioned regardless that there have been crashes during which planes started all of the sudden dropping from altitude, main variations set this crash aside.
On 1 June 2009, Air France flight 447 fell extra erratically and slower than the Boeing 737-800, in line with France’s Bureau of Enquiry and Evaluation for Civil Aviation Security. All 228 folks onboard the Airbus A330 had died.
Wang Ya’nan, the chief editor of Beijing-based Aerospace Data, was quoted by the International Occasions as saying that “it could possibly be a really severe technical failure during which the airplane inevitably enters a high-speed descent”.
He, nevertheless, additionally made it clear that the particular trigger can solely be decided after the black field is recovered and analysed.
In one other instance of a sudden airplane plunge, an Atlas Air Worldwide Holdings Inc cargo airplane all of the sudden dove down in 2019, albeit from a a lot decrease altitude.
A report by the US Nationwide Transportation Security Board mentioned the co-pilot was disoriented and pointed the airplane’s nostril in direction of the bottom. The cargo airplane additionally didn’t fall as quickly because the China Japanese Airways one did.

“The very first thing accident investigators are going to have to find out is: was the plane multi function piece when it hit the bottom, or did one thing fall off the aeroplane earlier than it hit the bottom?” Juan Browne, a Boeing 777 pilot and widespread aviation vlogger, informed the South China Morning Submit newspaper.
“The video knowledge to me means that the plane was in a single piece,” he added.
However others are sceptical about leaping to conclusions too quickly. Jean-Paul Troadec, a former director of the French Bureau of Enquiry and Evaluation for Civil Aviation Security, informed AFP the info was “very uncommon” and that it was “far too early” to attract conclusions.
“There’s actually just one factor that may get the plane in that vertical of a descent and hold it there, and that’s the elevator or the stabiliser trim,” Mr Browne defined.
He mentioned that even in such a “devastating impression crater” it was attainable for investigators to find the elevator trim jackscrew – a threaded bolt that controls the place of the trim.
“If you could find the place the nut on the jackscrew was positioned, you may get an thought of what the trim state of the plane was on impression.”
