What videos of the Jeju Air jet can tell us about the plane crash in South Korea

Scores of people were killed when a passenger jet crash-landed at an airport in southwestern South Korea, with the aircraft careening down the runway on its belly before bursting into flames.
Just two of the 181 people on board the plane survived, after the deaths of 179 people were confirmed, according to the local fire department. The two crew members were pulled alive from the crash site.
It is the deadliest aviation disaster to hit South Korea since 1997, when a Korean Airlines Boeing 747 crashed in the Guam jungle, with the loss of 228 lives.
CNN's Mike Valerio reports on the latest from South Korea and Richard Quest discusses what the videos of the jet may tells us about the disaster.

I am Korean and my coworker was one of the 179 victims of that accident. I am still in deep sorrow and I think other families feel the same way. I express my deepest condolences to all the victims.

Having a brick wall at the end of the runway is diabolical

[alann]

Imagine doing your best to successfully land a jet airliner without landing gear only to see a huge concrete wall in front of you. So stupid.

My condolences to all who loses their live and families. from Thailand

Imagine all were expecting to crossover to the new year😢
My condolences to the families that lost their loved ones.

The plane crash didn’t kill anyone, the barrier at the end of the runway did .

As a aviation maintainer my self, from what i can see and with the information being put out I would say that the aircraft had a complete hydraulic failure, these aircraft have 2 hydraulic systems and yes the engines provide power to both of those systems. the Boeing 737 does has a redundant hydraulic systems, typically consisting of two separate systems (labeled as System A and System B) to ensure continued functionality even if one system fails; this redundancy is a critical safety feature in aircraft design.

As we can see in the video the aircraft did suffer a bird strike to one of the engines but even with one engine out, the secondary " emergency hydronic system would be enough to lower the landing gear, operate flaps and reverse thrusters. on top of that these planes are equipped with an emergency mechanical system for the landing gear, allowing pilots to manually deploy the gear using a gravity-assisted mechanism in case of total hydraulic failure .
The engines directly provide power to the hydraulic systems by driving engine-driven pumps that generate hydraulic pressure for the aircraft's flight controls and other systems; essentially, when the engines are running, they power the hydraulic pumps which then distribute pressurized fluid throughout the hydraulic system.

In conclusion and in my opinion as others have stated, if the barrier was not at the end of the runway, then the aircraft would have hit the dirt and then would have been slowed down even more. most modern airports have a special section of runway at the end, that is designed to collapse under the weight of the aircraft to slow it down even more. think of it kind of like loose sand, the landing gear would dig in to it and slow the aircraft even more.
now in the event of a total hydraulic failure the pilots would treat this like a water landing, meaning they would not deploy reverse thrusters, why ? well because as shown in the video they only had one engine working, if they deployed reverse thrusters the aircraft would umm lets say" list" to one side or the other due to the uneven thrust on one side. this then would cause the aircraft to tumble and roll and break up . from what's shown, it appears that the pilots are doing every thing correctly, as per there training. also being that they had only one engine IF they did deploy the landing gear they still would not of had the power from the other engine to slow them down enough, despite what people may think, a aircraft doesn't stop by its breaks alone like a car does, the pilots were relying on ground friction to stop them, the sad thing is , is that there was a concrete barrier at the end of the run way .my heart breaks with all of the families of those who died .

Truly sorry for the poor people who lost their loved ones.

[mylife]

i feel sorry for the pilots. they would've been so on edge pulling this off, and probably even felt a glimmer of hope. then they saw the wall.

Dear Family members of the deceased, My deepest sympathies for your loss!! May all their souls rest in eternal peace.

[Patrick-gxuv]

This makes me sick to my stomach. Life can be so cruel sometimes. Rest in peace poor souls

[InterstateJ]

That’s terrible.. the 2 that lived may have the strongest case of survivors guilt…
Condolences.

[girlmiaful]

Heartbroken for those families. What more can you say, really. Just devastating.

[peachbae]

I had hoped that Korea could rise above everything in 2025 after such a challenging 2024. But hearing about this tragedy leaves me heartbroken. My deepest condolences go out to the families of the victims. May they rest in peace.

Such a sophisticated country that puts concrete walls at the end of the runway???

[sasakialinne]

I cant imagine the pain of the families its very heart breaking

[aoitakumi]

The plane has no fire whatsoever while on its belly, the fire or explosion only happened when they hit that concrete wall for whatever that was supposed to me. It got me thinking maybe there was a possibility that not that many people would die if that reinforce concrete was not at the end of the run away...

[bragastraat]

No flaps, slats, elevators, air brakes...amazing how the pilots could even touch down they way they did

[louismondo]

My sincere condolences to the families of those killed by this horrific tragedy

[keeliekalayidol]

If even one small bird can cause catastrophic damage to a plane in flight why have they not designed some kind of mechanism shield for the engines or components by now? They’re basically saying even a small single bird can cause a plane to crash!!!! Look it up. I’m never flying again.
