Here is a counter argument....
So who bought Blanchard, should be the question.
Another question; how can a structure(with more than one floor) come down in free fall? (and don't argue milliseconds here!) A structure that previously was sound and constructed to take hits of such magnitude.
Elementary understanding of physics is enough to tell You that shouldn't be possible(ie. You
don't have to be an architect or engineer to understand that). Collapsing floors have been used to explain this but that is not taking into account constructing a sound building, a building that can support it's own weight
and take on the elements. Just for starters...
