The violent actions of the plane would be easy to verify if the investigators had the black boxes from the plane.
Hmmm, now where are those boxes now, and just how unusual is it for them not to be in the possesion of the NTSB after a crash on dry land?
Side note: I do not care if the plane was shot down or not. In either case the deaths are on the hands of the terrorist scum.
I also lean to not shot down - but I do seem to recall that the flight data recorder was not recovered, and that not recovering it is unusual.
