Re: Witness account . . .
Someone being interviewed, sounding very professional like a fellow reporter, out for a morning walk with her husband reported seeing the accident occur. She states relatively certain there was an explosion at the juncture of the wing to the fuselage. A pilot also being interviewed -- as an expert for the news -- states this sounds like a central tank explosion.
Terrorism is not being ruled out (very sketchy data at this point), but it is also NOT being termed a terrorist act.
