Aircraft very low on approach. That is the big question. Why? Flaps and leading edges all in expected position.
This was not a premeditated emergency according to a pax. They knew nothing until the impact.
Eyewitness suggest that engines were making more noise than usual which indicates that the crew were trying to re-establish the 3 degree glide path after discovering they were dangerously low on approach. Unfortunately it was too late.
The aircraft main gear has broken away from the aircraft which suggests it landed heavy and slow.
I wouldn't like to be the skipper of this one.
Looks like soot marks on starboard side.
