Three Engineers—Geotechnical, Chemical, and Structural—Tell Their StoriesCaswell doesn’t buy the official narrative that would have us believe that the Twin Towers were reduced to concrete powder and steel — in under 12 seconds, no less.
Chemical engineers like Bruce Caswell acknowledge that jet fuel cannot do this. So what can?
“I find the collapse story for WTC 7 strange,” he said. “Most of the debris was immediately cleared away and the material was not properly examined. NIST's entire theory is based on a computer model that they created and not upon actual evidence from the scene. What further bothers me is that no one raised an eyebrow, not a peep, over the fact that the steel was removed from the site and sent to China on barges for recycling starting just two weeks after the collapse.”
“WTC 7 was constructed with a double-tubular design, where the exterior was made of a latticework of steel columns, steel beams. Inside this tube of steel was another tube of similar construction, designed to work together with the exterior tube to resist the lateral loads. This combination tube system makes it near impossible to have this building collapse at near free-fall acceleration into its own footprint — which it did — especially from a localized collapse in one portion of the exterior tube.”
