原来波音747坠毁时是这样的。

很可能是配载失衡。
这是货机。客机也是一个道理。
所以，飞机在起飞落地时，客人应避免在客舱里面走动。客人不多时也不要随意调换座位。配载失衡在小速度时是很容易出问题的。

这是YouTube的视频：

这么大的飞机对那点平衡会有影响？

My god, never seen this before. 好像机头拉的太高。

失速。

The airline has been operating the Bagram to Dubai route for a month. The aircraft had taken off on runway 03 at 15:30L and climbing through 1200 feet, when the nose of the aircraft nose sharply rose. The crew were heard on VHF air-band frequency reporting that some of the load of five heavy military vehicles in the cargo hold had shifted and the aircraft stalled. The aircraft crashed and erupted into flames on impact. The crash site was near the end of runway 03 within the perimeter of the airfield. All seven crew; four pilots, two mechanics and a load master were killed.

失速。

验证了。是配载失衡导致失速：
“some of the load of five heavy military vehicles in the cargo hold had shifted and the aircraft stalled.”

loss of speed resulted in loss of lift.

 

[月下独酌]

loss of speed resulted in loss of lift.

no

increase in attack angle due to weight shifting towards the rear resulted in increased drag, causing the loss in speed and thus stalling the engine

okay, you win.

 

[ForwardRetreat]

no

well, the engine doesn't stall, the aircraft does. when not enough lift is produced either due to low engine power or high pitch, the aircraft would stall and would fall off of sky. Engine could still be at full power upon impact if the pilot pushes the throttle to max trying to recover the stall after it takes place.

真惨啊。
