The video Stand for Truth has the clearest video images of the Twin Tower core remnants, both during and immediately after collapse, that I know of anywhere. It clearly confirms that the cores stood longest, after the internal collapse had stripped out the floor assemblies and the perimeters had consequently tumbled outward. This rules out destruction of the buildings by initial explosive segmentation of the cores.
NIST made many errors and frequently returned sloppy work, but their statement that after initiation, rapid global collapse became inevitable, is true. It is true by a very wide margin. This is why there has not been a massive outcry from the global physics and engineering communities.
