NIST found no corroborating evidence for alternative
hypotheses suggesting that the WTC towers were brought
down by controlled demolition using explosives planted
prior to September 11, 2001. NIST also did not find any
evidence that missiles were fired at or hit the towers.
Instead, photos and videos from several angles clearly
showed that the collapse initiated at the fire and impact
floors and that the collapse progressed from the initiating
floors downward, until the dust clouds obscured the view.
