Any experts who could voice opinion based on photos of B777 remains? Was it shot down by a small AIM or large SAM? The plumes coming from the crash site may indicate that the airliner did not disintegrate at 33,000 ft.
One of the first things that struck me as odd were some of the long skid marks on the ground. Another thing is that chaff (toilet paper they say) you can see in one of the videos.
