笔直向下，丝毫缓冲都没有，看了几个业内人士分析，很大可能是人为因素。
有上海机场的人说是机长欠款自杀。这个飞机上还有9位去训练的飞行员，损失巨大。

查了一下，前面估算都有偏差。8000米两分钟基本是不加力自由落体头朝下垂直坠落的速度。

In stable, belly-to-earth position, terminal velocity is about 200 km/h (120 mph). Stable freefall head down position has a terminal speed of 240–290 km/h (around 150–180 mph). Further minimization of drag by streamlining the body allows for speeds in the vicinity of 500 km/h (310 mph).

Airliners can descend over 8,000 feet per minutes if needed. A descent from 35,000 feet at that rate would have you down to 11,000 feet in 3 minutes or less. 现在的下坠速度超过了每分钟两万英尺，任谁也做不出这么大的动作。
