I just love the vocal track of a monitor watcher in this vid:
"Amm namanama um yuu su it dilyo lock up yee."

I want to make a song out of it.

Horrific.

There is a dashboard recording of an alternate view of the descent, you can see it did have some angle on it, 30ish deg or so? I can't link to it or find it now. It was on twitter, just a short time after the crash. Maybe someone else can find that and post it?

That crater looks similar to UA93, which impacted the ground at about a 40-45 deg angle, speed of 575mph (489 knots) or so. They did find the black boxes in that crash, but only tiny fragments of bodies adding up to about 600 pounds total. Fragments of plane were miles away, the only good thing about this one is that maybe because of the density of foliage any kind of parts recovered might be closer together, thus hopefully easier to find? 93 was a pretty open field. Remember, conspiritards took the tiny amount of recoved remains as proof of some type of criminality and coverup by the government.

Are there indications besides the obvious that this was for whatever reason, intentional? Could a structural failure or mechanical issue really cause such a steep descent from cruising altitude?

In an instant, this jet went from controlled level flight in cruise to a catastrophic vertical descent. The crew temporarily recovered from dive and started gaining altitude, but the dive resumed and it hit the ground near vertical.

I am pretty confident seeing the resulting video that the tail section is not present during the length of that video. Wing and engine on 1 side seems present but not sure, other side not visible.

Analysis of FR24 data indicates in last 2 minutes an abrupt extreme vertical descent followed by a steep vertical ascent, followed by a final extreme vertical descent till impact. Continuous loss of altitude with a temporary 'leveloff' after the 'climb', followed by increasing extreme rate of altitude loss.
I am not familiar with the airspeed data from FR24.
Pictures are showing popped rivets in several parts of the fuselage indicating over exceedance of design limits.

Somehow crew lost control of the vertical flightpath; likely loss of tail section, immediate or during the last 2 minutes of flight.
failure of rear bulkhead, collision in the air, runaway trim,we are just guessing right now.

Crew seems to have been fighting to get the aircraft recover from the initial steep abrupt vertical descent. Must have been horrific those last 2 minutes.

FR24? Flight Radar 24?

Data from the flight-tracking website FlightRadar24.com shows the China Eastern flight was traveling at around 30,000 feet with a cruising altitude speed of 523 mph before it suddenly dropped.

A fire ignited following the crash near the city of Wuzhou in Teng county, but hundreds of firefighters and rescue were dispatched to the scene and the fire was extinguished, according to the state-run China Daily. However, the outlet also reported a village official with the surname Zhou said the plane had "completely disintegrated" and he did not see any remains.


The aircraft that crashed was a Boeing 737-800. While Boeing has come under fire previously for crashes, it was the company's Boeing 737 Max that generated some of the harshest criticism over safety concerns.

There are differences in the aircraft, and Aerovise aviation expert Josh Verde told USA TODAY the Boeing 737-800 is a "tremendously safe airplane." Most accidents involving the plane have been runway-related.

In 2010, an Ethiopian Airlines flight, operated by a Boeing 737-800, crashed into the Mediterranean Sea, resulting in 98 deaths.

Here's what we know about Boeing 737-800:

How it happened:China plane crash, with 132 aboard, had frightening descent before impact

Chinese airline crash: Search continues for 132 people on board Boeing 737 that crashed in southeast China

This file photo taken on May 29, 2020 shows a China Eastern Airlines Boeing 737-800 aircraft parked at the Tianhe Airport in Wuhan, Chinas central Hubei province.
How many Boeing 737-800 planes are in use today?
The Boeing 737-800 has been in use for nearly 20 years, and Verde said they are one of the most common aircraft used around the world, primarily in the United States, Europe and Asia.

Southwest Airlines, the nation’s largest domestic carrier, flies Boeing 737s exclusively with 728 in its fleet at the end of 2021. That included 207 Boeing 737-800s with an average age of six years.

American Airlines had 267 737-800s, while United had 141 and Delta had 77. In total, the four major U.S. airlines have nearly 700 of the planes in their fleets.

Verde estimates in the U.S., there are roughly around 200 Boeing 737-800s in the air at any given time.


What's the difference between a Boeing 737-800 and a Boeing 737 Max?
The Boeing 737 Max was heavily criticized after two international planes crashed in 2018 and 2019, resulting in 346 deaths. The plane was grounded worldwide and wasn't allowed to fly until several changes were made and it got recertified by the Federal Aviation Administration, which it did in Dec. 2020.


The aircraft is used in the United States, but David Yu, a finance professor specializing in aviation at New York University in Shanghai, told The New York Times the planes are not back in service in mainland China yet.

Anthony Brickhouse, associate professor of applied aviation sciences at Embry-Riddle Aeronautical University, told USA TODAY the key difference is the Max is the newer version, the engine is located in a different spot and the Max is more fuel-efficient.

"I would encourage people not to automatically connect the dots between what happened today and what happened back in 2018 and 2019" Brickhouse said.


Is the Boeing 737-800 safe?
The 737-800, part of Boeing's next-generation family, has had some issues in recent years. In 2019, the FAA ordered the inspection of heavily used 737 NGs for cracks in wing supports, which found several planes had wing cracks.

However, Verde said the planes "don't have any ongoing areas of concern" and have had long, safe track records, alluding to how many airline companies use them today. He added the Boeing 737 Max was the first time he had seen the company cause a massive public scare.



"They're tremendously safe airplanes, and so the public certainly shouldn't have any concerns about getting on board one," Verde said.

Brickhouse said it's normal for people to feel uncertain about flying after a passenger plane crashes, but said it is still a reliable and safe plane to travel on, and investigations into the crash will lead to any necessary changes being made.

What could have caused the Chinese plane to crash?
Video taken of the flight showed the plane in a straight nosedive moments before its impact, something Verde said could indicate the flight crew lost control of the plane. He said the impact force of that happening is "tremendous," and there's no guarantee anything on the plane, including the black box, would survive.

"Systems problems or a failure of some type is typically the only time you would see a plane in that nose down dive of attitude when you're talking about an airliner," Verde said.

"The cause of the plane crash is still under investigation, and the company will actively cooperate with relevant investigations," the airline said in a statement Monday. "The company expresses its deep condolences to the passengers and crew members who died in the plane crash."

Brickhouse, a former student trainee at the National Transportation Safety Board, said one thing that caught his attention was the aircraft's sudden drop in altitude. The plane was around 30,000 feet before dropping to around 9,000 feet in under three minutes.

"That's not your typical descent rate for an aircraft," he said.

There is no timetable of when it will be known what caused the crash, but Brickhouse said investigators don't focus on one piece of evidence alone, and collected evidence and data will help piece together what caused the crash. USA Today.

understatement of the day.

[houseoftechno]

Last three minutes of MU-5735. See the temporary recovery from the initial dive where it leveled out and started to gain altitude. Then the final dive.

[houseoftechno]

Another graphic showing the altitude variations during the temporary recovery, followed by the final dive.

[houseoftechno]

Here is a chart of the final three minutes. The gray line shows the rates of decent and ascent.

Note the sustained climb rate during the recovery stage is as steep as the two dives. Hell of a roller coaster ride there! At least the pilots gave it a fight.
