Obeid, structural engineer, with a masters degree in Engineering from UC Berkeley, of Fremont, California, says: "Photos of the steel, evidence about how the buildings collapsed, the unexplainable collapse of WTC 7, evidence of thermite in the debris as well as several other red flags, are quite troubling indications of well planned and controlled demolition"
Ronald H. Brookman, structural engineer, with a masters degree in Engineering from UC Davis, of Novato California, writes: "Why would all 110 stories drop straight down to the ground in about 10 seconds, pulverizing the contents into dust and ash - twice. Why would all 47 stories of WTC 7 fall straight down to the ground in about seven seconds the same day? It was not struck by any aircraft or engulfed in any fire. An independent investigation is justified for all three collapses including the surviving steel samples and the composition of the dust."
Graham John Inman, structural engineer, of London, England, points out: "WTC 7 Building could not have collapsed as a result of internal fire and external debris. NO plane hit this building. This is the only case of a steel frame building collapsing through fire in the world. The fire on this building was small & localized therefore what is the cause?"
Paul W. Mason, structural engineer, of Melbourne, Australia, argues: "In my view, the chances of the three buildings collapsing symmetrically into their own footprint, at freefall speed, by any other means than by controlled demolition, are so remote that there is no other plausible explanation!"
"In my opinion WTC7 was with the utmost probability brought down by controlled demolition done by experts" -Hugo Bachmann, Professor emeritus for structural analysis and construction at ETH and former Chairman of the Department of Structural Dynamics and Earthquake Engineering, Swiss Federal Institute of Technology.
