WTF, why they have to put a wall at the end of the runway? so sad. that is 170 real lives that could have been mostly saved without that fxxking wall.
Here's the wall in question, apparently (I can't be sure that's correct, of course, link taken from another comment):

Does it look like it can stop a plane to you? No freaking wall would do that.
Most likely it was the uneven terrain that caused the front of the plane to hit a mound and caused the rest to collapse behind it.

it is basically a crime endangering public safety.
