Danny Jowenko says it is a CD. His assessment is that the lower supports were taken out and the building dropped. Well since that is what occurred why should the building fall in a different way? The lower supports DID give way. One above the penthouse first followed by the other 2 after imbalanced load. Deceptively, which increasingly seems to be the realm of the "truther", he is not shown the preamble where the penthouse gives way. By deductive reasoning(you really should give it a go!) his surprise that this is the same day as the two WTC collapses indicates without question that he says they were NOT controlled demolitions. Otherwise, why would he be surprised?
