And unnamed structural engineers all over the world agree too right oh elevator boy-sheep 20 pilots STREET CORNER JEEBUS?WTC 7 had not been hit by a plane, so it was apparently the first steel-framed high-rise building in the known universe to have collapsed because of fire alone.
New York Times writer James Glanz quoted a structural engineer as saying:Â[W]ithin the structural engineering community,[WTC 7] is considered to be much more important to understand [than the Twin Towers],Â because engineers had no answer to the question,Âwhy did 7 come down?Â
From a purely scientific perspective, of course, there would have been an obvious answer.
Scientists, presupposing the regularity of nature, operate on the principle that like effects generally imply like causes.
Scientists are, therefore, loathe to posit unprecedented causes for common phenomena. By 9/11, the collapse of steel-framed high-rises had become a rather common phenomenon, which most Americans had seen on television.
And in every one of these cases, the building had been brought down by explosives in the process known as controlled demolition.
From a scientific perspective, therefore, the obvious assumption would have been that WTC 7 came down because explosives had been used to remove its steel supports.
Huh Eh !
Oh but those same engineers still use SFRM protection against fire in their designs...why would that be again?
Oh right, because fire can destroy structures.
