In your scenario how do you explain the total devastation of the aircraft?
rgbrock1, this is one of the issues still to be clarified. The long debris field and the lack of noticeable "craters" points to a relative fast and flat impact.
On the absence of big(er) pieces, I have seen recently some local pictures with substantial chunks of fuselage skin, several meters long and aslo one where a wheeled bulldozer is riding in the debris field.
Could it be that the big pieces have been moved and we do not have pictures of them?
