Structural engineering and demolition expert, Rosie O’Donnel, is putting on her truther (tin foil?) hat once again:
And, just the same as last time Popular Mechanics is on the case again to expose her as the fool she is:
For more detail on one aspect of the talk showâ€™s conversation, our expanded report in book form, Debunking 9/11: Why Conspiracy Theories Canâ€™t Stand Up To The Facts, describes the volcanic forces that Ms. Hasselbeck referenced on Monday: â€œ[A] seismology report prepared at Columbia University provides a glimpse into how that damage [to the southwest corner of WTC7] was caused. The report notes that the collapses of the Twin Towers caused little ground instability, but nevertheless discharged a massive amount of energyâ€”as much as 107 joules in the kinetic energy of dust and debris. Except for temperature, the effect was similar to the energy contained in the pyroclastic ash given off in volcanic eruptions. â€˜Only a very small portion of the [gravitational energy associated with the collapse of each tower] was converted into seismic waves,â€™ the report states. â€˜Most of the energy went into deformation of buildings and the formation of rubble and dust.â€™â€
Never underestimate the amount of energy stored up in a standing skyscraper or the kinetic energy of a fueled up plane moving at 500mph. It’s sad to see so many people buying into this conspiracy bullshit.
