Why was there a wall at the end of Korean crash runway?

Apparently the wall was at the end of the runway that planes normally travel away from during takeoffs and landings. For some reason, this plane came down going in the opposite direction from the usual. Also, it touched down much further along the length of the runway than was normal and at higher than normal speed.

A lot of questions and irregularities.
 
Lots of airports are wedged into cities. My guess is the wall was to protect nearby homes.

The wall was part of a concrete housing for the ILS landing system, without it the number who died would have been much less if at all. Why it was built so strongly is strange and needs to be investigated.

Another thing that needs to be investigated is if you watch the video , why weren't the wheels down.
You can't put the breaks on unless the wheels are down.
It is going to be interesting.

Aviation experts have raised questions about an "unusual" concrete wall near the runway and its role in the South Korea plane crash that killed 179 people.

Because it's part of the glide-slope approach system and has to be at a specific height and position within that system for pilots to use it correctly.

It is one of several landing system aids that ensure pilots are properly aligned with the runway and are approaching it at the correct angle of descent and altitude. It gives a visual warning to the pilots if they are improperly aligned.

So, which is worse, that the pilot(s) of one airliner misjudged their landing and crashed hitting part of this system or, not having this system and having more airplanes crash?

The concrete structure holds a navigation system that assists aircraft landings - known as a localiser - according to South Korea's Yonhap News Agency.

At 4m high, it is covered with dirt and was raised to keep the localiser level with the runway to ensure it functions properly, Yonhap reported.

The glideslope provides vertical guidance, and the antenna is typically located 750 to 1250 feet down the runway, and 400 to 600 feet from the side of a runway's centerline. You can usually find the glideslope shed next to the runway's aim point markers.

ILS: How The Instrument Landing System Works

The Instrument Landing System (ILS) is a radio navigation system that provides precision guidance to aircraft approaching a runway.

The explanation for the wall sounds like BullShit.

The article was asking why the localiser housing wasn't more frangible.

Show me even one runway that has a wall at the end of it.

There aren't many, the runway was only supposed to be used one way only. This explains in far more detail.

What is a localiser back-course approach, and how does it work?

Steve Baker's answer: So for the benefit of non-pilots, let’s first explain what a “Localiser” is - then we’ll get to the “back-beam”/”back-course” part. WHAT IS A “LOCALISER”? A “Localiser” (or more completely, an “Instrument Landing System Localiser” - or ILS), is a device to help pilots land...

Well, if you look at Google Maps / Earth, there isn't a wall right at the end of the runway at Muan. What this plane hit was well beyond the end of the runway. That meant it had to be going pretty damn fast when it ran out of runway. This landing assistance device is off the runway on the 10 end and nearly to the boundary fence of the airport itself. You can see it clearly on Maps / Earth.

Even the OP embedded video at the beginning (the BBC one) shows the plane went well beyond the end of the runway to hit that berm and device. It wasn't as if it was right at the end of the runway, it's about 500 feet beyond the end of the runway, including the approach ramp portion of it. The end of the actual runway is probably closer to 750 to 900 feet from it.

Had the berm and locator not been there, the plane likely would have gone through the airport permitter fence and onto the road that runs around the outside of the airport and beyond.
