驾驶员手工降落,但没控制好高度,
快落地时飞机高了。
驾驶员拉控制杆降低高度,但降的有点急,头部要撞地,驾驶员又急忙拉起机头,这时飞机尾部着地撞击地面。
尾部撞地面之后产生向上的反作用力,飞机质心在中部,导致机身/头部加速扑向地面(所以飞机里的乘客由于惯性飞向机舱顶部)。
One of those on the flight, Elliott Stone, told CNN that he thought the plane was approaching "a little high (then came) down a little sharp.
"All of a sudden, boom, the back end just hit and flies up into the air and everyone's head goes up the ceiling," said Stone, who added that he ended up jumping out the plane without using the stairs or an evacuation slide.
