Three-part webinar series. Each part is about 1 1/2 hours. As a 501(c)(3) nonprofit organization dedicated to conducting research and providing education about the complete destruction of the three World Trade Center skyscrapers, our courses give architects the technical knowledge and analytical framework with which to evaluate the most likely cause of those building failures. Course Description: Never before has a steel-framed high-rise collapsed from fire. Why, then, did three such buildings collapse on September 11, 2001? In Part 2 of “9/11: An Architect’s Guide,” Richard Gage, AIA, provides an overview of the most important evidence related to the explosiveness of the Twin Towers’ destruction. Much like that of WTC 7, the destruction of the Twin Towers exhibited most of the features of controlled demolition. In 2005, the National Institute of Standards and Technology (NIST) concluded that the Twin Towers’ destruction resulted from the combined effects of the airplane impact damage and ensuing fires. Is NIST’s explanation for these unprecedented structural failures valid? Decide for yourself after watching this informative one-hour presentation. Using the information presented, you will be able to evaluate which of the two hypotheses — fire-induced failure or controlled demolition — is more consistent with the evidence. Learning Objectives: Participants will be able to: 1. Describe the characteristics of building fires and the aspects of high-rise design that contribute to make fire-induced failure in steel-framed high-rise buildings a rare occurrence. 2. Recognize the distinct features associated with fire-induced failure and the distinct features associated with the procedure of controlled demolition. 3. Describe step-by-step the series of structural failures that the National Institute of Standards and Technology found to be the most likely cause of the collapse of World Trade Center Twin Towers. 4. Analyze the physical evidence and the dynamics of the collapse of the Twin Towers according to how consistent it is with the competing hypotheses of fire-induced failure and controlled demolition.

En agosto de 2016, un antiguo empleado del Instituto Nacional de Estándares y Tecnología (NIST) empezó a revisar los informes que su agencia había publicado años antes sobre el colapso del World Trade Center. Lo que encontró le estremeció hasta la médula. En esta conmovedora entrevista de media hora, Peter Michael Ketcham cuenta su historia del descubrimiento de que la organización, donde había trabajado durante 14 años, había suprimido deliberadamente la verdad sobre el evento más crucial del siglo 21. A través de su disposición a mirar abiertamente a lo que no pudo ver delante de él durante 15 años, el Sr. Ketchman nos inspira a creer que todos podemos armarnos del valor para confrontar la verdad — y, haciendo así, finalmente curar las heridas del 11S.

This video, which we found on January 24, 2017, provides a closer up, stationary view of the Plasco Building's collapse initiation.

It is not yet known how many firefighters and civilians were killed, but early reports say that anywhere from 20 to 50 are feared dead. Based on preliminary analysis of many videos of the collapse, Architects & Engineers for 9/11 Truth (AE911Truth)—a nonprofit that represents more than 2,750 architects and engineers who are calling for a new investigation of the 2001 World Trade Center disaster—strongly urges President Rouhani, Iranian authorities, and the people of Iran to thoroughly investigate the possible use of explosives in the Plasco Building’s shocking demise, and to act swiftly and decisively to preserve the physical evidence. Let us be clear: It is impossible to know at this early stage what caused the structure to suddenly come crashing down. But, as with any proper forensic investigation, no plausible scenario should be ruled out—especially when the available data seem to support that scenario. Here, six separate videos we have compiled (https://youtu.be/_MgJTa7SDaY) show what appear to be—and in some cases sound like—explosions emanating from the tower in sequential patterns as it began to crumble. The building’s tumultuous fall is then accompanied by thick, energetic, rapidly forming plumes that are reminiscent of what we see in controlled demolitions. Further, the BBC reported that the fires were nearly extinguished—and that emergency personnel and occupants had begun reentering the building—when the collapse unexpectedly occurred. Indeed, videos display very few flames and a thick black smoke—signs of a low-temperature, oxygen-starved fire. Moreover, the inferno was limited to the upper floors, yet the entire 17 stories came down in just a few seconds. We at AE911Truth are all too familiar with events in which a prematurely formed narrative makes it harder to subsequently ascertain what truly happened. We therefore adamantly caution against rushing to any conclusions as investigators work to uncover the truth surrounding this national tragedy in Iran. Should the Plasco Building collapse be found to have been caused by pre-placed explosives, sadly it will not be the first time that explosives were used to bring down a burning high-rise while people were s ... https://www.youtube.com/watch?v=ERln7nV77UI
