If you want to consider the accidents involving an aircraft being put deliberately at 90 degree descent, let's not forget about Air Maroc 630....

West Sweden 294, Valujet, there are other ways an accident aircraft can basically go straight to the ground without it being deliberate.


West Sweden was only a 20 degree nose down pitch, and Valujet went nose down at low altitude after fires burned through the control cables after obviously fighting a fire for some minutes. This crash occurred from Top of descent after level flight then completely nose down at 90 degrees to the ground. I doubt that happened after a fire had burned through control cables

I believe the MAX is still be grounded in China for commercial passenger services, so it should be not part of the discussion.

"China, the first country to ground the 737 MAX, is the only major global market where the aircraft is still not in commercial service, and its return is taking longer than expected at a time when domestic demand is declining as coronavirus cases rise."

Let's hope CVR and FDR are retrieved soon. It must have been a high speed impact so who knows in what condition these will be...

CVR recording should be able to rule out a deliberate crash or not fairly quickly. Onboard fire, not so sure, crew would have sent a distress signal I suppose. An aircraft does not fall out of the sky the moment a fire starts. Instrument failure with a consequent loss of situational awareness would be possible I guess, although a catastrophic result is more likely in darkness (West Sweden, Ethiopian).

I'm wildly speculating like everyone, no need for the attitude.

The curve looks smooth, like can only happen when the aircraft is being controlled (by the pilot or autopilot).

Now if there are only a couple of data points and the curve is interpolated, then it's a false impression.

Using the angle on the video to detemine if it was deliberate or mechanical is very vague. While the nose was pointing downwards, the actual trajectory is not visible. Many mechanical problems can lead to the upset the aircraft was in, paired with the visual angle it is hard to determine in what direction the aircraft actually moved.

From certain angles the EL AL crash in Amsterdam would have looked like a 90° vertical impact too

We all speculate here.

But all I can say is one thing. May the 133 sounds on board Rest In Peace. If the video is true, I could not imagine a worse way to die. That would be a horrific few minutes with unimaginable terror.

I can only hope they were unconscious after the initial descent but honestly I think they would have been conscious till the very end.

I think the 737NG is mature enough an endemic problem causing a catastrophic failure would have been identified by now.

But the mode of operation these days is immediate grounding for PR purposes, lest the media jump on you for “putting lives at risk”.

It also suggests that it’s another problem with a Boeing aircraft, diverting attention from possible causes like Chinese pilot action or error or a Chinese airline’s fault.

I remember an Airbus expression 3 years ago in conjunction with Pilot training: Lets hope we will not be affected by an accident as in china everyone will try to shift the blame to the airplane rather then accept human faults.
Tee grounding of all 737-800 seems to be the first outcome. For me not unexpected.

The EgyptAir A320 over the Med (MS804) went down pretty quickly after a fire broke out in / near the cockpit. Sadly, its CVR and FDR stopped recording quickly after starting the descent.
Same for MH17.

There's also the Metrojet A321 which dropped like a rock after a bomb separated the empennage from the forward fuselage.

The Swiftair MD-83 in Mali crashed with its nose pitched down 80° after a stall in cruise.

Many possible reasons for a crash from cruise altitude.

If the above video is real the only way to be forced into a direct 90 degree dive is absolutely deliberate action by whoever was behind the controls.

In previous deliberate pilot actions, did the deliberate actions typically start during the early phases of flight (like soon after reaching cruising altitude)?

In this case, the descent started about 100 miles from the destination, which would be the normal time to start a descent, right?

What about the possibility of unintentional, deliberate action? Such as pilot disorientation in the clouds during descent?

The one people used to speculate that it was pilot suicide. So yeah the one from this post:

If that video is true, then the plane crashed at a 90º angle.


That could also be with 90° bank angle and 45-90° nose down but impacting with a 30-60° angle because the aircraft moves away from the camera. It is really hard to make out trajectories of moving objects in space when you have no reference.

While of course there is always a way, suicide doesn't match to me, this aircraft is at top of decent. I have spoke to a couple of China Eastern pilots in the last few hours (I'm an instructor who has trained for them in the past). Their policy is both crews must be seated 20 mins prior to TOD. This was well past that point.

It was slightly inverted and certainly could of appeared to have struck the ground at a straight down angle, animation below:

https://admiralcloudberg.medium.com/par ... ba92226c5e

The DHL 757 also impacted the ground at 70+ degree angle after losing it's vertical stabilizer. I'm not saying this flight wasn't deliberately crashed, but I don't think that's the only plausible explanation at this point.

Hmm, this is an interesting discussion. I didn't think of CFIT initially because the FR24 graph looked so steep. It was about 100 miles from its destination (it was around Wuzhou, destination Guangzhou), so I guess that would be the time to start the descent.

The FR24 graph is quite coarse, the 2 data points at the start of the descent are:

6:19:59, 457 kt, 29100 ft
6:22:16, 455 kt, 9075 ft

The delta is 2m17s (137s), -2 kt, -20025 ft. That would be a descent rate of -8770 fpm over that 2m17s, while speed was steady.

What could that indicate? The descent rate is too fast for a normal descent, right?


Flying 455 kt at 9075 ft is quite an overspeed. The aircraft was increasing speed and descent rate during the descent.

Yes, that's the case here. The next data point after the start of the descent was over 2 minutes later. FR24 only publishes very coarse data by default.

Sometimes they will manually download the fine data from their sources and publish that for flights of interest.

That noise is from much closer to the camera, and sounds like someone hammering a nail on a rooftop with typical between walls echo. This is coherent with the reverberation on the voices in the video.

Another factor I realized that is that FR24 Speed is ground speed, not airspeed. Ground speed is only horizontal speed, right? So it could have been gaining airspeed during the descent without increasing ground speed.

So the descent was actually reversed for a while and it started climbing sharply again? :shock:

In 15s it went from +8,448fpm to -13,248fpm. :crazy:

It is sad to wake up in the morning and find out an aircraft has crashed with the likelihood of many people dead.

It appears from preliminary and independent information that something happened suddenly and catastrophically. For many of us here due to biased political beliefs as to China and past sudden crashes into terrain, many will be quick to blame a bomb, mx failures, fire, pilot error or suicide. Those same political biases will also mean many not believing the investigation reports, that they will blame Boeing or non-China source, cover up anything to do with the airlines or pilots.

Perhaps something like AF447 occurred where pitot tube or control component issues led to autopilot errors, the situation made worse by bad info and reaction to what happened by the pilots. Hopefully the recorders will be recovered intact enough and not cut off during the decent to get the info needed to properly investigate and get to the truth as to what happened. This aircraft was delivered in 2015 so should have a FDR with many points of information.

Speculating:
a decompression and subsequent emergency descent looks not probable. 6000 ft / min looks too high for an emergency descent.
the fact that we have data of the descent may mean that at least some of the electricals were still working. An explosion and in-flight, high altitude break up (TWA 800) is unlikely to me.
on-purpose CFIT also not probable to me, with the 2 people rule in the cockpit.
engine / engines flame-out not probable to me, the fight envelope will be different, the plane has a certain glide capability.
flight controls malfunction and subsequent in-flight destruction due to fatigue / overstress and subsequent detachment of that part looks more probable to me.

Doesn’t necessarily need to be one pilot off the flight deck for it to happen. Makes it easier, but Egyptair happened with two eventually on the flight deck, and ere was a JAL attempted crash in the 70s that happened with two pilots and a flight engineer on the flight deck.

All it takes is one being physically stronger and overpowering the other. It’s why the practice of getting a flight attendant to sit in the flight deck while one pilot goes to the toilet is stupid. Most flight attendants are young thin women, most pilots are physically strong men. I doubt the typical flight attendant would have any chance stopping a pilot in that case.

Thank you, but a controlled rapid descent due to decompression and subsequent break up in flight doesn't seem plausible, or?
Maybe the decompression damaged some of the control surfaces?

I don't think anyone made a political biased opinion here yet, rather than yourself pointing fingers at other people.

If you have watched Air Crash Investigation, and followed most of the episodes, it is always true that the investigators start with all possibilities on the table before they are eliminated with more evidences suggest otherwise. In fact, in any investigation, aviation of criminal, it is always the process of eliminate suspects in order to find the most plausible one.

Before the official reports and hard evidence from black box, everyone is entitled to express their opinion on what could have gone wrong and what they believe had happened. Most posters here have tried to keep things civil and I personally do not see any political biased opinion until yours come along. May I remind everyone here please keep the topic on the crash itself? I find your post lightly offensive by pointing blames to fellow posters here 'being politically biased'. I would like to suggest you to post our points on AF447 without attacking other posters. Thank you for your attention.

Many comparisons on here with previous losses, but the one that came to my mind first I haven't seen metioned on here, PSA1771 - near vertical, high mach number etc.

Could a stall + fall + recovery attempt + failure to recover explain this altitude/vspeed table ?

From the data available it looks like a catastrophic failure or a midair collision with a military aircraft/drone

The data looks very interesting.

Within 21s (6:20:43 to 6:21:04) the aircraft got into an upset that caused it to increase vertical speed alot. The change of speed is over 1000ft per minute, going from vs=0 to -30000ft per minure in 21s, thats almost 24ft per second or around 8m/s^2. You would have started to feel very light inside the aircraft (0.2G).

Over the next 10s the descent stabilised and some effort to reduce the descent was made but until 6:21:40 the descent was continuing. Now it gets even more extreme.

From 6:21:40 to 6:22:05 the vertical speed went from -22000ft per minute to 8500ft per minute what again is around 7m/s but this time together with gravity, putting the acceleration at 17m/s^2 or 1.7G. From that the aircraft went into a steep decent again with another 7m/s^2 acceleration against gravity reducing the feel back to 0.3G. Thats quiet the roller coaster even excluding any rotational accelerations.

Keep in mind FR24 often has many more data points than they publish on the site. It would overload their connections to be publishing everything, but hopefully they will release everything they have now.

Looking at the altitude data, at 062043Z was 29000 ft and stable, then at 062059Z 27025 ft with a -21696 ft/min vspeed.
at 062155Z the vspeed becomes positive, definively a recovery attempt

At that speed they would pass out very quickly.


Nobody passes out because of speed.

You can pass out because of acceleration/decelaration, so because of a change of speed.

Constant speed doesn't harm anyone.

Absolutely awful, RIP to those onboard. Could this be some kind of jackscrew or other mechanical failure?


Possibly. However, it's not part of the 737 MAX family which had that issue.
