The speed/time in which they lost attitude most likely knocked them out. The sudden change in air pressure could be fatal.
If they were knocked out, then likely the pilots were too. But there is evidence that the plane had some semblance of control before the final dive, which implies that the pilots were trying to recover. If pilots retained consciousness, then likely many passengers did too.
A faulty mechanism on the rudder brought down two 737s of an earlier model back in the 1990s, one near Colorado Springs and the other near Pittsburgh. Those planes ended up diving almost straight down before running out of altitude. I'm not saying that this is the cause of the China Eastern crash, only that such a thing can happen without the pilots trying to have it happen.
Those planes had a problem where only one angle-of-attack indicator (the plane has two) was used for this special "autopilot" to decide the plane's nose was too high under certain conditions. So when all the wrong things combined(starting with a failure of that AOA indicator), the MCAS started shoving the nose down, and basically dove the plane into the sea or ground.
"The flight had taken off from the city of Kunming just after 1 p.m and was en route to Guangzhou.
"China Eastern Flight 5735 was traveling 523 mph at around 29,000 feet around 2:20 p.m. when the plane suddenly fell from the sky and erupted into flames.
"The plane plummeted to 7,400 feet before briefly regaining about 1,200 feet in altitude, then dove again. The plane stopped transmitting data 96 seconds after starting to fall.
The crashes of the Boeing 737 MAX were characterized by the plane, while climbing shortly after takeoff, started nosing down inexplicably. Pilots tried to horse the nose back up, and had momentary success, but the plane kept nosing down harder and harder until the pilots could no longer control it, and the plane dove into the ground or ocean.
That sounds a little like this plane in China, but with some differences. This one climbed all the way to cruising altitude (29,000 feet) without any misbehavior. More than an hour after takeoff, it started nosing down. When it went down to 7,400 feet, it nosed back up and even gained around 1,200 ft altitude. But then it dove again, all the way into the ground.
Was the plane a 737 MAX? A special system built into that model (MAX) was responsible for two crashes several years ago. Other 737 (non-MAXes) did not have that system.

Not a pilot here. Question? Could this have been caused by a cargo area load shift?

I am not an expert, don't have a pilots license but have a basic understanding of how planes work. No fire seen in the video, the aircraft looked to be intact during its nosedive. Even if both engines where to fail at that height and speed the pilot should of been able to coast the plane 50-55 miles. Assuming both engines failed and the aircraft didn't start descending to keep airflow thus letting it glide the plane could go into a uncontrollable dive. This is a horrible horrible accident, the blackbox will be recovered and will tell the story. If I had to guess this was pilot error or suicide. RIP to all aboard and hopefully the families get the answers they want and deserve.
I'm going with suicide. That thing didn't "fall" out of the sky. That thing was flown into the ground.

I'm saying 'no' on that. Reason(s): There are others in that cockpit who know how to fly, for one. Two, it wouldn't be going that fast.
Well this brings out the Boeing haters all over again, can't wait to see how the NYT handles this one. The haters so want this to be a MAX, sorry it's a -800 delivered new in 2015. Simply too soon to speculate, hopefully the orange boxes survived to give some clues. Even my pro-pilot site I use is pretty much a garbled mess right now.

You should read the article, rather than go on and on about the 737-MAX, while repeatedly asking others to find out information that was easily available in the article (beginning right in the summary below the headline).
Sheesh...

Pitiful. Just pitiful.
Must you drag your sociopolitical grievances into every utterly unrelated topic?
At some point in it's descent it gained 1200 ft in altitude.
There was a similar crash with Air Alaska flight 261 off the California coast in 2000. The jackscrew controlling the rear stabilizer broke due to neglected maintenance. Plane was 8 yrs old. That was a MD 80 type though.
That put the plane into an uncontrolled pitch downward.
