"The plane was already on fire when it crashed to the ground. The crash caused a big explosion," said witness Tegegn Dechasa at the site, littered with passenger belongings, human remains, and airplane parts.
"The plane was in flames in its rear side shortly before the crash. The plane was swerving erratically before the crash."
Farmer Sisay Gemechu, said: "The plane seemed to be aiming to land at a nearby level open field, but crashed before reaching there."

I saw a clip of this witness talking--and yes too: all in this field of After-crash procedures are justifiably wary of Most 'eye-witness' reports--but he gave a pretty-much simplest-sequential story in minimal words; he'd have to be severely disturbed to have just made it up..

So.. ... we wait for an indubitably STRANGE sequence of events as may only become convincing IF... those black-boxes have been so armored as to sustain a Drill-in at 'est. 400+ km/hr' (way-fast at the max altitude it ever reached, pre-crash.)

Y.P.B. in spades ..so many genuine Humanitarians: key people amongst such a rare breed (amongst The Whole Damn Human Race)--to quote Mark Twain, in a posthumous work.. ;-/ :-/

Flight Aware is at least populated with actual pilots; doubtless there are many other such sites. Wonder which One? ..is the most incisive as well as al-punte informative (??)
