This guy is a 777 pilot.

It depends on the angle of view... from straight ahead, the fall would be vertical and from the side, a true idea of the slope would be presented.

Rather than think climate change and the corona virus as science, think of it as the wrath of God. Feel any better?

The possibility exists that the aircraft is veering to one side or the other, however in this situation, more down is consistent with a crash and it would eliminate the possibility that the pilot was able to counteract the negative influences that led to the crash. Once again, we are looking for patterns not quanta.

 

[IRstuff]

Even the dash cam video is at an awkward angle, looking up and to the left; it's not clear whether the descent was even as steep as shown in the other video.

TTFN (ta ta for now)
I can do absolutely anything. I'm an expert!

The impact zone is very small. That would mean it was very perpendicular.

As for the 787 tail, the article says horizontal stabilizer but that is also a composite construction aircraft and has nothing in common with the 737 design outside of having 2 engines. I don't think it's constructive to speculate a link between the two.

Tug, some here would just like to disparage Boeing, regardless of facts.

 

[Alistair_Heaton]

its a 737-800 not a 787.

Its a 1960 design there is loads of stuff in the MAX threads on its tail and trimming system.

If the tail is off there is nothing to keep the plane level and it will go basically vertical. This will be the same for all aircraft.

Is that wing part at the crash site?

 

[Alistair_Heaton]

The video that Nukeman posted has some good bits on the jack strew at the back. That rotating shaft is a single point of failure.

It doesn't meet modern certification standards but they got it through on the 737-800 NG a few months before the modern certification standards came in. And were then able to grandfather it onto the max as they only played around with the control system to it not the actual system.

To be fair that system now has flown millions of hours and is well inside the 1 in the 10000000 fatality criteria for safety analysis.

I am going to be truly impressed if the data modules have survived that crash though from the cockpit voice recorder and flight data.

If its a technical issue they might be quiet forward releasing data. If its human error I don't expect them to release it.

 

[Sym P. le]

Last one. North is to the top of the image this time.

Their history may not be stellar...

This reference shows Embraer to be the safest manufacturer, with Airbus and Boeing virtually tied for second.

Read some speculation on-line that the pilot may have deliberately crashed the plane - similar to Egypt Air flight 990 and SilkAir flight 185.

 

[Alistair_Heaton]

Most of the 737 crashes apart from the MAX are pilot error. Although its up for debate if some of those pilot errors were actually technical but Boeing were very good at covering their bum. The 737 rudder hard over problems the outcome is extremely suspect.

There is also a colossal difference between pre merge Boeing company of engineering excellence. And the current abortion of MBA management.

 

[Sym P. le]

As I review the Chinese road system in proximity to the crash, I think the freeways have extremely restricted access. The only on/off ramps are onto other freeways. All of the locals have little to no access.

 

[Alistair_Heaton]

Thanks for the updates.

I presume your more local than I am in Europe. What's your feeling for how they are going to investigate it?

 

[Sym P. le]

I'm not local, just hit upon an idea that helped zero in on the crash location.

Off the top, I think the flight data and voice recorders are lost (as in able to provide any useful information) as are any parts that stayed with the plane as it went down. That shouldn't stop them from digging up every last bit of metal they can find in that hole just in case there is a clue to be found. From an investigative perspective, the recorders are always the last to go in the ground so that's a positive. If parts fell off the plane prematurely, it covered 17 miles from the start of decent with much of the terrain awkward and thickly overgrown. When the United DC-10 flight went down over Iowa/S.D., the turbine disk was revealed during harvest. This won't be the same.

That leaves an investigation of the crew. Not much more to say. There is always additional information that we won't be privy to so stay tuned. There are always more revelations.
