This directly contradicts what was stated at the news conference, ie, no contact with ATC to indicate any problems?

Exactly Dean, I think it is somebody trying to stir by spreading fake news...

Dirk I think it's like covid news, or Ukraine news, who is to tell which is fake news?

Aerodynamically, the engine out theory makes a certain amount of sense.

Yes...unless...the Chinese authorities are trying to cover up their ATC incompetence and don’t want it to be known that there was communication prior to the dive.
I’m not one for conspiracy theories, but I’m starting to distrust government statements of any sort!

Looking at the speed / altitude graph shown on page 1 of this thread there is no decay in the speed, as to how accurate flight radar is over China I don't know but if the graph is correct it would rule out a stall.

Airline business Weekly briefing article

Clamour for China Eastern crash theories is at odds with reality

Few incidents prompt greater focus on the airline industry than a fatal crash.
Following the tragic loss of a China Eastern Airlines Boeing 737-800 on Monday, the scrutiny – informed or otherwise – has been intense, in general reporting and particularly on social media.

The internet is awash with theories regarding the cause of the crash, notably including those carelessly based on imagery from a computer reconstruction of an incident that happened 25 years earlier.

During such times, the commentators worth listening to tend to be those urging people to wait for further evidence to emerge.

So far, aside from flight-tracking data, the few fresh details released via official channels include acknowledgements of failed attempts by air traffic control to contact the aircraft as the incident occurred and of the damaged cockpit voice recorder being recovered.

One certainty is that in China’s huge aviation market, the incident marks the first fatal crash since 2010.

And within the wider context of airline safety, the crash has occurred in an industry that has a remarkable safety record, as was reflected in IATA’s recent summary of 2021 data.

None of that is, of course, any comfort to those who have lost loved ones this week.
As ever, commercial’s aviation licence to connect the world is contingent on it doing everything within its power to establish why catastrophic incidents have occurred, before acting promptly on any recommendations. The first part of that process may take some time.

As investigators continue their work, many commentators will already be tired of having to point out that the crash is unrelated to the safety issues with the 737 Max programme. The requirement to do so undeniably reflects that the latter programme and Boeing’s reputation are still very much in the public consciousness, even as hundreds of Max jets fly without fanfare in markets around the world.

On the latter point, it is not unreasonable to question whether this week’s crash might further extend the long wait for Max jets to fly again in China, on the grounds of optics alone.


** I am flabbergasted by this crazy new(ish) reality of fake news following any world event, who are these people who create these fake stories and fake imagery, and what is their motivation? It's incredibly juvenile in that it achieves nothing - it's one thing to make fake news in a campaign during a conflict or war situation but in a tragedy like this what possible gains can be had from publishing a fake story as fact when we all know the cause and truth will ultimately come to light? Just bizarre, my general thinking is that any theory released before the preliminary and final report is speculation and hearsay - particularly in a crash as puzzling and devastating as this with so much riding on the answers

I think its driven by the youtube channels and blogosphere. The intent isn't to report news, there isn't any yet other than the fact of a crash. It's all about "creating content" to drive up page views. If it's later proven to be wrong, so much the better as there's now more content to create. Very frustrating. Empty vessels make the most noise and all that...

Another possibility perhaps? Pilot lost his licence when this pic became viral.

I generally keep my opinion to myself BUT watch Juan Browne’s Utube Channel if I feel the need to know what’s going on. Or Dan Grider & Scott Perdue. Sensible measured approach from the trio . All an asset to aviation.

Scott Purdue and Juan Brown are brilliant, Dan Grider, in my opinion, thrives on controversy, and although he has a wealth of knowledge from experience I seldom agree with his anti-authority attitude and he jumps to the most controversial option very readily and has been wrong but never admits to it. His blatant disregard for the victims of crashes and the investigators serves only himself and leaves a bad taste even if he gets the ultimate cause right sometimes. ..each to their own I guess.

For 65,000kg flaps up maneuver speed is approximately 210 knots indicated (Vref 40 + 70) but this is for lower altitude, The actual stall speed will be around 180 to 190 KIAS. I can't find the high altitude buffet speeds, I'll keep looking.
