Ad una visuale ravvicinata dei detriti che vengono espulsi dalla Torre Sud del World Trade Center, non appena la sezione superiore cade verso est mostra numerosi "proiettili" fumanti che sembrano comete. Molti di essi possono essere visti esplodere. Uno di questi è qui seguito. Esso espelle due frammenti, entrambi espongono delle esplosioni secondarie. (Nota, il frammento in salita sulla sinistra del "proiettile" in esame sembra essere un oggetto in rotolamento che alterna dal nero al bianco all'invisibile. Passa dietro uno dei frammenti descritti nel video.)

Do the seismic data from the events at the World Trade Center corroborate the eyewitness, video, and forensic evidence of controlled demolition? (Please see our FAQ on this subject at AE911Truth.org: http://www.ae911truth.org/news/faqs.html for greater detail on this question from which the following is taken.) Short Answer: Yes. It is beyond doubt that the seismic data recorded by Columbia University's Lamont-Doherty Earth Observatory (LDEO) in Palisades, New York, corroborate the eyewitness, video, and forensic evidence of explosions both before and during the collapse of all three WTC towers — and explosions even before the plane impacts into the Twin Towers. Our conclusion, which is based on our review of the studies conducted by the researchers and seismic experts listed below, match the LDEO's seismic data. But because the LDEO did not rely on its own data when it issued its report, our conclusions do not match the LDEO's conclusions. Thus, our conclusions also contradict the conclusions of the FEMA and NIST reports, which relied upon the LDEO report's conclusions and not upon the original seismic data. We also recommend that you read the article, "Point TT-7: Why Did the Twin Towers Collapse? The Seismic Evidence,” by the 9/11 Consensus Panel.

9/11: An Architect’s Guide | Part 1 - World Trade Center 7 Course Number: AE911-AAG-OD1 Live three-part webinar series. Each part is about 1 1/2 hours long Architects & Engineers for 9/11 Truth is 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 provide the technical knowledge and analytical framework with which to evaluate the most likely cause of those building failures. Course Description: In Part 1 of “9/11: An Architect’s Guide,” Richard Gage, AIA, provides an overview of the most important evidence regarding the destruction of World Trade Center Building 7 (WTC 7), a 47-story high-rise that was not struck by an airplane. The damage WTC 7 suffered from the collapse of the North Tower was found to be inconsequential. It had fires that were similar to those that have occurred previously in high-rise buildings. Yet it fell symmetrically into its own footprint in the manner of a typical controlled demolition. In 2008, the National Institute of Standards and Technology (NIST) concluded that WTC 7’s destruction was caused by normal office fires that burned “at temperatures hundreds of degrees below those typically considered in design practice for establishing structural fire resistance ratings.” Is NIST’s explanation for this unprecedented structural failure 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 Building 7. 4. Analyze the physical evidence and dynamics of Building 7’s collapse according to how consistent they are with the competing hypotheses of fire-induced failure and controlled demolition.

La ligne de toit du WTC 1 (la Tour Nord) commence sa chute brusquement, continue son accélération vers la bas à environ 64 % de l'accélération de la gravité et disparaît dans un nuage de poussière. Le bâtiment rencontre donc une résistance équivalente à environ 36 % de son poids. Cela implique, par contre, que la force exercée sur la partie inférieure du bâtiment n'est également que de l'ordre de 36 % de son poids - beaucoup moins que si le bâtiment était immobile. Les données de l'accélération prouvent donc que la chute de la partie suprérieure du bâtiment ne peut être responsable de la destruction de la partie inférieure. Une analyse complète a été publiée dans l'article intitulé "Destruction of the World Trade Center North Tower and Fundamental Physics," Journal of 9/11 Studies, Vol 28, Feb 2010: http://journalof911studies.com/volume... (Quelques notions de base de calcul et de physique sont cependant nécessaires.)
