South Korean 737-800 Crash

Looks like a dual engine failure. Both A & B system hydraulics quit when that happens. Probably didn't have time to crank up APU to provide electrical power either.

Thinking that too, but there is significant heat coming from the right engine in the video, unless that is residual. Tragic, but the analysis will be interesting.

It's difficult to determine if there is something hot coming from the engine, or was it fuel from a fuel line/fuel tank rupture?
 
The landing gear can be dropped by gravity. The main cause of death here is zero though process putting a wall at the end of the airport as well as a solid wall around it that I saw on the news. Other wise if they had more runway all would have been good.
 
you can clearly see the plane crashed into the raised installation at the end of the runway. Without that it could have slid much further as there was little infrastructure beyond the airport's end...except the cinder brick wall and a couple of roads.

There appeared to be heat shimmer trailing the engine as the pilots began their flare, before touchdown. I only noticed it on the head on view.
The heat shimmer is the RH (#2) engine, which suffered the bird strike earlier, and is still running, just at a reduced thrust level. As for the LH (#1) engine, it looks to me like after the bird strike, the pilots shut-down the wrong engine, as there is no apparent heat signature (from a running engine) on the #1 engine when the aircraft approaches for the runway for a 2nd time. It wouldn't be the 1st time in aviation history that a pilot chose the incorrect engine to shut-down. The pilots had tried the approach once, but initiated a go-around, and the timing of the go-around was rather brief before attempting the 2nd landing approach in the (opposite) direction seen in the spotter video (of the crash). In the process, and the short interval for attempting the 2nd landing, it's obvious they didn't run through the checklist for an engine-out landing, and thus omitted the steps for setting the flaps for landing, as well as deploying the landing gear. In the worst case, they could have used the Alternate Extension System, which is three (3) independent T-handle releases located at the bottom of the center aisle (between the pilots). The system uses gravity, and as such, takes a little longer to deploy than when using the Normal System w/Hydraulics, but it would have got the LG down regardless of any System A/System B hydraulic issues.

What I find absolutely appalling is the Koreans are now starting an investigation into all 101 Boeing 737s registered in South Korea. For what? It doesn't appear to be an airframe issue, rather pilot error as well as some likely Crew Resource Management (CRM) issues. Bird strikes unfortunately happen all the time in aviation - a single engine-out does not doom a 737 to a belly landing. Full stop.

The airplane is a popular scapegoat which allows authorities to “save face” by taking attention off the crew.
 
For someone not involved in aviation at all, I found the comments made by former fighter pilots Mover, Gonky, and Wombat interesting. To summarize, something compelled the air crew to want to bring the plane down quickly instead of going through the usual check lists, and we won't know that until the investigators have done their thing.

Mover makes and interesting comment that the video of the bird strike/compressor stall could be mirrored as sometimes YT does that with portrait oriented video. If so, it might explain a few things. Here's the video so you can hear it from Mover, Gonky, and Wombat themselves:

They’re all current airline pilots. One has 737 experience. The guy who strafed a few cows.
 
I’m wondering if that airplane had the “OLD” style fuel shutoff levers or the “NEW” style version? The OLD style levers would make it easy to shutdown the wrong engine in a panic.

According to this, it was 3 minutes between the Mayday and Go-Around call to touchdown. Seems awfully fast, especially for landing on an unplanned runway. Still don’t want to draw too many conclusions, but the official report will be an interesting and tragic read.

One of the big questions I've heard is why the crew didn't just land, but rather did a go around. Perhaps there's something in the voice data recorder that will explain the rationale for not just landing.

The Aviation Herald said:

"...The aircraft then attempted another landing in adverse weather conditions..."

Huh? Where did they get this?

Adverse means unfavorable, hostile, or harmful.
Unfortunately, I don't really know. Everywhere I have seen has said the weather was darn near perfect. My guess is that it is just a mistake- perhaps they inadvertently added "weather" and meant to say "attempted another landing in adverse conditions", or something along those lines.
