South Korean Plane Crash Kills 177

[EagerBeaver]

I know there are some pilots or aviation engineers on this board so please explain to me what I am seeing in this video. It looks like the jet is skidding down the runway with no landing gear or wheels deployed- on its belly- and therefore, it cannot brake or slow down. It then hits a concrete wall and explodes in a fireball. Obviously it could not brake because there are no wheels down. Why is there a concrete wall rather than one that gives away at the end of the runway?

Why would the pilot have tried landing the plane without landing gear, but more significantly. why could the pilots not deploy the landing gear? I heard some reports of birds flying into the wheel wells? Could this event have possibly prevented the deployment of the landing gear? Is there not an emergency unlock system that allows the landing gear to deploy by way of gravity?

From the video flaps and slats for low speed flight do not look deployed resulting in a faster touchdown speed of 200+ knots to keep the airplane from stalling and falling during the approach. Normal touchdown speed is 145 knots with flaps n slats extended. Pilot most likely misjudged and touched down too long down the runway. The Pilot "might" have realized this too late and "might" have hit the throttle in a panic for a last second go around but Failed and just increased the speed while sliding on the runway. An engine failure is usually no problem cause there are 3 redundant hydraulic systems to activate control surfaces and landing gear.. Whatever happened is a very bad type of "Cascade effect" of failures for Boeing not having the flaps n slats and gear deployed with an engine out. Gear up landing is bad but with no flap n slats landing is exponentially bad because of the extra 55Knots which exponentially increases the landing roll. Why the gravity drop of the landing gear did not work given it is simple springs and cable activated is unknown. Badly trained pilots forgot about those gravity gear extension handles in a box by the pilot seats? What a mess.
