Search teams have found a black box from the China Eastern Airlines plane that crashed on Monday, Chinese state media reported on Wednesday, which could provide clues as to why the Boeing 737-800 jet carrying 132 people nosedived out of the sky in China’s worst aviation disaster in 12 years.
Key Facts
One of two black boxes from the China Eastern Airlines flight MU5735 has been recovered after two days of searching, a Chinese aviation official announced at a press conference on Wednesday, according to state broadcaster CGTN.
Black boxes—which are actually painted bright orange to make them easier to find—are recording devices built to withstand extreme conditions like explosions, high temperatures and crashes that capture flight data and cockpit discussions to help investigations into any accidents or incidents.
The black box is “severely damaged” and investigators are unsure what information it carries, according to CGTN.
All-out efforts are being made to recover the second black box, said Mao Yanfeng, the director of the accident investigation division of the Civil Aviation Authority of China (CAAC), according to multiple media reports.
Investigators are still unsure as to what caused the jet to rapidly lose speed and altitude in a near-vertical drop—it fell around 20,000 feet in one minute—and Mao said communications records show the crew “maintained normal communication” until the sudden drop in altitude.

I am betting a bomb on board in the aft cargo bay blew the tail off.
That is certainly plausible.
No one has claimed responsibility AFAIK......................
Thats Data not Date
Dove, climbed, dove.
VS may have come off from stress exceeding Vne.

Hopefully not pilot suicide. And they were able to steady it for a few seconds so maybe not.
Some of those descent rates work out to over 350 miles per hour. I don’t believe a tumbling, out of control air frame would get anyway near that speed. Interesting how it slows way down around 7-8 thousand feet then rapidly picks up speed again.
How did it dive like 5 miles in altitude in 2 minutes more or less maintaining speed? Some kind of issue with the software like with the 737-max?
The fact that there is a data steam to flightaware shows the engines were turning the generators for electric power. That also means this plane had engine thrust plus gravity in a near vertical drop it’s surprising it didn’t go supersonic in that attitude with engine power. The recovery at 7500 feet shows at least partial control authority so dead stick is also out the window. This has the hallmarks of a suicidal pilot or a bad actor gaining access to the controls and ensuing struggle.
Here is a review of the SWA Boeing 737-700 engine failure back in 2018.

From the report:
“Portions of the left engine inlet and fan cowl separated from the airplane, and fragments from the inlet and fan cowl struck the left wing, the left-side fuselage, and the left horizontal stabilizer. One fan cowl fragment impacted the left-side fuselage near a cabin window, and the window departed the airplane, which resulted in a rapid depressurization.”
I wonder how deep they had to dig to recover the box? I think it was intentional. Even if both wings blew off, it still would not nose dive that way. That was no free fall.
“The black box is “severely damaged” and investigators are unsure what information it carries, according to CGTN.”
I worked for Fairchild Weston, which at the time had 80% of the crash recorder business. There were two sections to the box. One was where the electronics was housed and it was a moderately heavy metal probably not much thicker than something you’d find in an instrument rack. The electronics led into a 1/4 inch welded, armored box containing the recording media. The actual media was suspended in beeswax. The volume of the beeswax was enough that a fuel fed fire, which should last less than thirty minutes, would boil the water in the wax, thus keeping the inner media module at no higher than boiling water temperature. The steam escapes through several small holes for the purpose. The box is highly engineered to survive a huge impact, simulated in testing by what’s called a “hammer drop.” The rest of the box is designed to withstand conditions that exceed the theoretical and tested conditions the tail of the plane would see in the worst possible crash...straight down at predicted speed with engines running.
I told you that to say, I’d be shocked if the recording media turned out to be so damaged the data could not be recovered. If that’s the case then something beyond a “normal” crash took place.
Trump's fault.
LOL
This suggests the empenage was gone entirely.
Yes....................
“Yes....................”
But then there is that sudden 10-second upward trajectory followed by the final plunge. If the empenage was gone about the only thing that could account for that deviation would be some sort of movement that allowed the wings to create enough of a drag to overcome the descent; but I’m trying to figure out how and why that would occur.
