You are correct.

Judging on the debris field seen in pictures and the position of the a/c, it appears to have been moving at a good rate of speed upon impact. With 80mph winds reported and severe tstorms, I hope that the pilots would have known better than to even attempt this landing (obviously).

I'm no expert, but how much would a microburst play a roll in this if that had happened? Or a major wind gust from behind/low-level windshear?
