The smaller clip above was taken from this segment of the Naudet Brothers' DVD. Only cropping and panning techniques were used - there was no use of sharpening or edge-enhancing filters.
Looking at the upper right-hand corner of the building we see a rapid series of small explosions travelling upward just as the building itself begins to fall. The size, placement and timing of these "puffs" is very consistent with squibs from cutting charges of the type used in professional controlled demolitions, and in fact nothing but small explosive charges could create such an appearance. The decreasing volume of the building from the collapse itself could not create enough pressure to cause such localized high-velocity effects, and this early in the collapse would have only created a modest overpressure.
