Homework. Thanks Go兄。Happy New year.

视频显示，韩国飞机以机腹高速滑行，撞上土堤，爆发出一个火球，而可能的鸟击、起落架未展开以及跑道尽头的混凝土障碍可能都是造成悲剧的原因。

 

 

Video showd that the South Korean plane crashed into the floor  when gliding in plane's body height, exploding  into a fire ball.  But possible hiting a bird, not extending undercarriage and the concreate wall at the end of the runaway  are all possible reasons of  the tragety.
