They Still Can’t Get Their Story Straight: Conflicting Theories of Fire-Induced Collapse 20 Years After 9/11 | Part 1: Twin Towers_on 9/11 Free Fall

Coming up today and every Thursday at 7:00 pm Pacific – 10:00 pm Eastern – 03:00 GMT
911 Free Fall

On this special episode of 9/11 Free Fall, AE911Truth CEO Roland Angle and Director of Strategy Ted Walter join host Andy Steele to critique a recent presentation on the World Trade Center building failures by Najib Abboud, a managing principal at the engineering consulting firm Thornton Tomasetti.
Before his former company, Weidlinger Associates, merged with Thornton Tomasetti in 2015, Abboud led Weidlinger’s studies into the destruction of the Twin Towers and Building 7 as part of the litigation efforts of developer Larry Silverstein.
In this presentation, Abboud puts forth Weidlinger’s theory that the Twin Towers collapsed due to the heat-induced failure of the core columns. This theory differs significantly from NIST’s theory that the perimeter columns failed first, as a result of being pulled inward by the heat-induced sagging of the floor trusses.
Abboud asserts that all of the studies supporting fire-induced collapse have converged around certain findings. But, in reality, they involve very different collapse initiation mechanisms, and none of them actually analyze how the destruction propagated following collapse initiation.

Angle and Walter methodically refute Abboud’s claims and explain how the NIST and Weidlinger theories are as much at odds with the evidence as they are with each other. In Part 2, Angle and Walter will examine the multiple conflicting fire-based theories for Building 7’s destruction, which are even more numerous and diverse than those for the Twin Towers.
