It was a

"world shock"

for the tragedy of a Boeing 737-800 passenger plane, China Eastern Airlines Flight MU 5735, a Chinese domestic aviation.

fall in the manner of a head-to-head

Then a fire exploded

Mountain area of ​​southern China's Guangxi Zhuang Autonomous Region

As a result, 123 passengers and 9 crew members, including 132 people, are all believed to have died.

According to Chinese local media reports, the

Boeing 737-800

passenger plane

Departing from Kunming, Yunnan Province at 1:11 p.m., scheduled to arrive in Guangzhou, Guangdong Province at 3:05 p.m., but disappeared from the radar at 2:22 p.m. in the city of Wuzhou.

Guangxi Zhuang Autonomous Region

The final speed is almost 700 kilometers per hour.

Before disappearing, the aircraft lowered the flying ceiling quickly.

From an altitude of 8870 meters to 983 meters in just 3 minutes.

The "I Want to Be a Pilot"

Facebook page

posted an interesting message, saying that the plane went down like a pencil.

How is it possible?? “Airplane upset” Loss of flight posture Normally, an aircraft has very good flight stability, even if the engine is completely shut down it will still be able to glide from the lift force. Persistence from wings and height(potential energy) converted to velocity(kinetic energy).

(Imagine when a paper plane is launched from a height.

It's the same even if we put our heads down and let go.

It will still fly.) Not that when there is no engine it will fall like a rock.

Now, it depends on how much height you have will change to how far you can glide.

And will it be able to support it until the airport or the area where it is safe to land or not?

There are only 2 cases for an airplane to descend like a pencil:

1. The wings fell off both sides.

(This could be caused by an explosion or a very high G-force acting on the wing, which is almost impossible in a passenger plane) resulting in no lift.

and agreed to that

2. Pan to control the direction (control surface) forcing the aircraft to stay in that position.

This may be caused by a malfunction of the aircraft system.

or caused by the force of the pilot

which usually

Pilots will be trained to correct aircraft upset recovery on a regular basis.

And there would be absolutely no way to let the plane descend like that, except on purpose or by the flight control system.

locked in that position

and can't really control

Compared to both 737Max cases, the MCAS crash occurred shortly after takeoff.

And the drop doesn't come down like this. However, today's case of #MU5735 still requires a lot of data to analyze and deduce the root cause.

In this regard, the Special Thai Rath Online News team

Had the opportunity to talk to "news source" who is an airline pilot as a

"flight teacher"

looking at this matter.

If a plane crashes at such a speed

An analysis of two such pages may be possible.

But...personally, I still feel puzzled.

how it happened and it was considered "strange" and "very unusual"

To understand, the flight instructor explained that most aviation accidents don't look like this at all.

Suppose there is a problem with the plane.

engine off

It will be able to continue flying as far as 100 kilometers. Losing a long distance with such a speed, only 3 minutes to the ground is very unusual.

People in the aviation industry may think that

Can the plane crash like this too..?

Personally, I am confident that the cause of this tragedy

It's probably not from the engine shutting down...but it might be from the flight control system, which doesn't mean the wings are off.

But there may be a problem with the ground system.

Make the head come down..

The weird thing is "why did you land this position?" if the plane was damaged.

It must have been severely damaged.

Another case that has been noticed is the case of forcing the machine to embroider the head down...ask if it can be done.

The answer is that pilots can already.

because the pilot can control the plane already

But it's something that is very difficult to analyze.

In the end, you'll have to look at the black box and investigate.

When asked about the history of aviation

Has there ever been an incident like this? The same flight instructor revealed that he had read it in an article.

that he stated

There may be a rudder that the knots are loose or loose, but that's not the point where the head hits the ground like this.

Because the main main body is wings, can still support the machine.

Except that "the wings are all falling off" as we have analyzed..

But the possibilities are very difficult.

almost impossible

The more the aircraft production is checked every step.

There will be an officer to check again.

Let's assemble it one by one until it's done. If the wings come off that easily.

It's probably a manufacturer's problem.

which the Boeing

Should have come to investigate the aircraft accident.

In addition to the two observations mentioned above, an aeronautical instructor, who is a veteran of commercial aircraft aviation, also remarked that this time is considered an unusual period.

Due to the COVID-19 outbreak, the number of flights has been greatly reduced.

make pilot yourself

Not flying as much as before, the "leisure" from work may cause a mistake.

Usually, they may not make mistakes because they do it regularly, but when they don't do it often, it may lead to "leisure".

Previously, airlines in the Middle East had "incidences" that were not accidental.

The pilot had set an altitude of 0 to climb from the airport.

did not return

but instead pressed his head down, near the house of the people, which was caused by a mistake

that may go to set some buttons

This is an unprecedented mistake, something that the International Air Transport Association (IATA) and Qantas Airways consider risky, which I personally do not know. Is flying in China back to normal?

Investigation issues after this

will have to look at the communication between the pilot and the aviation tower because if the plane if there is an abnormality

or reduce the distance to abnormal height

at least the pilot

or assistant pilot

what to say

which if there are no words

It's probably a mistake.

Personally, I consider it "shock" with this incident because there are only very unusual things, not about visibility.

or the weather

that might fly into him

or used to happen often

But this descent from a height of 29,100 feet, landing in 3 minutes, reaching the ground looks baffling.

believe that many agencies in China

Should be investigated, including the manufacturer itself must be investigated clearly

Because of what happened, it affects the company that produces it.

Must be cleared as quickly as possible.

because if all flights are suspended in this model

may affect more

The process of investigating aircraft "manufacturers" is a key factor in removing the resulting data.

Must provide technical clarification. In addition, the Department of Civil Aviation is also required.

of that country

get involved

and there may be agencies from international

neutral in the audit



Courses in Resolving Emergency Situations

The flight teacher explained that normally when learning to fly.

Skills are reviewed on the simulator every 6 months, with rehearsals for incidents such as engine failure.

fire engine

what is called

“Fixing the situation where the aircraft is not normal

in an unusual flight

which such corrections, such as the sudden upward plane

Lift up normally or if you press your head low, only see the ground like this, how to fix it?

which the nature of the plane

will try to keep myself in a normal state

The pilot tried to force it to come out in a direction that was easier to correct.

Steps to Troubleshoot Plane Crashes


1. Resolve the situation.


2. Try to communicate to the HQ for help.

which the machine crashes in 3 minutes, it is still time

However, if there is no communication

It's still difficult to answer.

Because we really are not in that situation.

Maybe I won't be able to say it, it's possible...
