it's waiting for the black boxes to be recovered and untill then it's all speculation.
great find on the vids and pics

In cruise mode, as MH5735 was believed to be, planes are typically on autopilot, meaning “it is very difficult to fathom what happened,” Chinese aviation expert Li Xiaojin told Reuters.

At 29,000 feet (around 8,800 metres) and nearing their destination, the pilots would have been preparing for landing. But instead the plane plunged directly down in less than two minutes, catching fire as it hit the forested hillside.

This could point to a power outage, Aerospace Knowledge chief editor Wang Ya’nan suggested in China’s Global Times newspaper yesterday.

“It is very likely that the aircraft lost power at cruising altitude, resulting in the pilot losing control of the aircraft,” he said.

“This is a very serious technical failure in which the plane inevitably enters a high-speed descent.”

Incredible to see that final couple of seconds.

This is one where I’ll be extremely interested to see the ‘final’ report.

This is very cool, Club. Some interesting insights from knowledgeable people there!

That dashcam footage I mentioned is on there.

TOTAL loss of aircraft power?
I don't think so.
Each engine powers an independent power buss. The APU has it's
OWN separate power buss. Each of those 3, by itself, can power the ENTIRE aircraft and every system, and also provide all the bleed air required for pressurization.
There are backup and emergency batteries as well, for things like emergency lighting for the cabin.
And the emergency flight control instruments (compass, altimeter, airspeed indicator, and artificial horizon for blind flying) also have a separate emergency power supply, totally independent of any other power source on the aircraft.
And there are the main aircraft batteries, which will power critical equipment for 45 minutes to an hour, so they can reach the nearest airport.
So I don't think it was a power failure.

Just my opinion. Others may vary.

Elevator or stab trim failure or one pilot had a heart attack and fell on the yoke whilst the other was in the bathroom.

Even if it did stall somehow they could regain control after falling and lowering pitch to gain airspeed to bring it back to stability. Stall ruled out.

Even in the event of a total nose drive you can recover it as you have excellent air speed.

To be in such a position something would have to have messed with:
A. Elevators/Stab trim
B. The ability to recover despite a high speed nosedive

Both A and B could be related to the actual part that makes them work. The hydraulics/servos.

I did a 3 plot... observing:

there are 2 similar actions at the start of each plunch: a huge 60° or more westward displacement from the previous location.
And these changes were much larger than the corresponding heading (named track in the data) value change.
Perhaps a huge "slide in the air" by a sudden tail loss, explosion, or ... 1 or more sensors giving false values.

For me this resembles the kind of fall when a sudden bulkhead disintegration happens.

Agree. I posted to this DR thread a few graphics and pics sourced from that PPRUNE thread, and visa versa. I go to PPRUNE for discussions on all of the major crashes. Fascinating speculation from aviation industry experts.

It is a minor pain in the arse to start an PPRUNE account. They are heavily moderated and quite snobbish. All posts by low-count members are individually screened and many are discarded, so you can't junk post your way to being full-fledged member. They don't really want non-pilots sniffing around and the members like to tell newies to STFU even on the tech forums, but tend to say it in professional pilot-speak.

One or more PPRUNE posters pointed out that the "temporary recovery" climb scenario in the FR24 data and flight renderings could actually be a malfunctioning pressure transducer as the jet was dropping 30000ft at near- or supersonic speeds. I agree that instrument could put out erroneous data in that environment.

There are reports of a sonic boom with that descent. From a pilot's perspective, it is more likely that the plane dropped straight down (rather than the partial recovery scenario of the FR24 data) in order to reach those speeds.

I am going to go ahead and call it now, before the recorders are examined: Somebody intentionally augured that jet. I will bet one ban stick that my prediction will be confirmed.

I'm going with suicide. The flight profile is identical to Egypt Air 990. https://en.m.wikipedia.org/wiki/Egyp...0-ntsb-f1.jpeg
