A/c flipped to its back before crashing,
If you look at the picture #9, the last in the series,
you can see that the a/c must have been already
in at least 60 deg left bank.
The wing then hit the ground and a/c cartwheeled.
No chance for survival, parts of the fuselage dug into soft, swampy soil.
It has been announced today, that still one body is missing
and heavy excavating equipment will be used to dig out
the missing parts and probably the body.
Regarding little or no fire, the engines, as the heaviest,
must have been thrown far forward by the cartwheeling fuselage,
away from wings full of fuel.
Also most of the fuel might have been already spilled after the wings
hit the trees 1 km before final impact.
Just my guess.
