[2] This is NIST’s theory in their own words: “The two aircraft hit the towers at high speed and did considerable damage to principal structural components: core columns, floors, and perimeter columns. However, the towers withstood the impacts and would have remained standing were it not for the dislodged insulation (fireproofing) and the subsequent multifloor fires.”

Taken from: NIST: “Final Report of the National Construction Safety Team on the Collapses of the World Trade Center Towers” page 4.

Therefore, the NIST theory is a “fireproofing theory”. If the fireproofing was not removed the buildings would not have collapsed according to NIST.

Plane damage was therefore insignificant:

Thomas Eagar, an MIT professor of materials engineering who supports the official theory, says that the impact of the airplanes would not have been significant, because “the number of columns lost on the initial impact was not large and the loads were shifted to remaining columns in this highly redundant structure” (Eagar and Musso, 2001, pp. 8-11).

Professor Astaneh-Asl of University of California:said “‘The [plane] impact did nothing to this building,’ he said with admiration.” CNN News, Oct 5, 2001.
