Preliminary results of a two-year study looking into the destruction of World Trade Center 7 indicates that fire could not have caused the collapse. To mark the 15th anniversary of the 9/11 attacks, the collective 9/11 Truth movement gathered in New York City for two days of street actions, outreach, and the “Justice In Focus” 9/11 Symposium. At the symposium, organized by the Architects & Engineers for 9/11 Truth, the Lawyers Committee for 9/11 Inquiry, and other co-sponsors, there was a heavy emphasis on the possibility of a civil or criminal trial as a means of exposing the truth about the 9/11 attacks. Many 9/11 researchers now focus on the mysterious collapse of building 7. A number of 9/11 family members point to the collapse of WTC7 as a possible crack in the official story that could spark a new national conversation on the events of that day. WTC7 was not hit by a plane that day; however, it collapsed at 5:20 p.m. according to the National Institute of Standards and Technology (NIST), the official cause for the collapse was office fires. A growing number of family members, activists, architects and engineers question the official theory for collapse and are seeking a new investigation into WTC7. In May 2015, a team of researchers from the University of Alaska Fairbanks began a two-year investigation of the collapse of WTC7. Dr. J. Leroy Hulsey, of the University of Alaska Fairbanks, and two Ph.D. research assistants are partnering with the non-profit Architects and Engineers for 9/11 Truth for a two-year engineering study known as “World Trade Center Building 7 Evaluation.” The researchers are using finite element modeling to evaluate the possible causes of World Trade Center Building 7’s collapse. “We will investigate the collapse. We probably will not be able to tell them what caused it, but I could tell them what did not,” Hulsey told MintPress. I am approaching it like most forensic engineers would. We’re looking at the structure itself, trying to put together all of the details of what was available, and in this case very little was available. Because most of it has been destroyed or it’s locked in vaults somewhere. So I have very little to work with. Hulsey explained that he addresses issues raised by NIST, but will not be reading anything about NIST or other previous studies. “I have to maintain an open scientific mind. I don’t want to be led down a path that others have gone down,” he said. “I will read about it once we reach our final conclusions and then cross-check to make sure we don’t have any issues with respect to the science.” During an interview at the Justice In Focus Symposium, Hulsey said that the team has already investigated the theory that fire caused the building’s collapse. “It is our preliminary conclusions, based upon our work to date, that fire did not produce the failure at this particular building.” When their study concludes in April 2017, Hulsey and his team will allow a panel of experts to analyze the data and submit the study to peer-reviewed journals. The researchers are promising a “completely open and transparent investigation into the cause of World Trade Center Building 7’s collapse,” and will post every step of their scientific process on WTC7Evaluation.org. The WTC7 Evaluation project will also include a review by a committee of technical experts who will vet the research being conducted by Dr. Hulsey and his students. Ted Walter, Director of Strategy and Development for A&E 9/11 Truth, is in charge of working with the professor and raising money to fund the WTC7 Evaluation. Walter told Activist Post that the project began in May 2015 and should should wrap up in April of next year. “They are coming up with different scenarios of how hot the fires could have been in different parts of the building, and then for the next 6 months they will be running tests and scenarios,” Walter told Activist Post. “The last few months, early next year, will be all about putting the findings into a final report.” Stay tuned to Activist Post for updates on Dr. Hulsey’s study.

The firemen at the scene could see the building was going to collapse because of the damage it received. Shouldn't you paultards be moving on to something original like what trump and Dick Cheney may have been doing at Bohemian Grove?
NIST NCSTAR 1A, WTC Investigation, FINAL REPORT on the Collapse of World Trade Center Building 7 At page xxxvii: Structural damage from debris did not cause the collapse.
http://www.youtube.com/watch?v=cgOGmUo9O2Y The NIST Final Report on World Trade Center Building Seven contains a simulation of the collapse. The simulation differs significantly from the videos of the collapse taken on 9/11/2001. Neither the simulation nor the explanation proposed by the NIST is consistent with the observed facts. After first denying it, NIST now admits that WTC7 dropped at free fall acceleration for 2.3 seconds. Only an unsupported and unobstructed structure can drop at free fall acceleration. Another mystery of WTC7 is that a collapse supposedly caused by fire was simultaneous rather than progressive. NIST proposes that the interior of WTC7 underwent a progressive collapse, leaving only the facade standing. Then, the facade collapsed simultaneously and intact. This explanation is not credible because the collapse videos do not show any damage to the facade at a time when the interior was supposedly completely destroyed. Only a few windows were broken when beams and floors were supposedly ripping loose and plummeting to the ground level. In addition, the explanation begs the question of why the facade collapsed simultaneously instead of progressively, and why it survived the collapse of the interior, only to fall by itself. Nor does NIST explain free fall acceleration of the facade. If the facade was so flimsy and weak as to collapse at free fall acceleration, why was it strong enough to survive the collapse of the interior? If it was strong enough to survive the collapse of the interior, why did it collapse suddenly, intact, and at free fall acceleration for 2.3 seconds? https://www.nist.gov/el/faqs-nist-wtc-7-investigation Questions and Answers about the NIST WTC 7 Investigation Contact: Michael E. Newman, michael.newman@nist.gov (link sends e-mail), 301-975-3025 September 19, 2011 (updated 6/27/12) [...] The analyses of the video (both the estimation of the instant the roofline began to descend and the calculated velocity and acceleration of a point on the roofline) revealed three distinct stages characterizing the 5.4 seconds of collapse: Stage 1 (0 to 1.75 seconds): acceleration less than that of gravity (i.e., slower than free fall). Stage 2 (1.75 to 4.0 seconds): gravitational acceleration (free fall) Stage 3 (4.0 to 5.4 seconds): decreased acceleration, again less than that of gravity This analysis showed that the 40 percent longer descent time—compared to the 3.9 second free fall time—was due primarily to Stage 1, which corresponded to the buckling of the exterior columns in the lower stories of the north face. During Stage 2, the north face descended essentially in free fall, indicating negligible support from the structure below. This is consistent with the structural analysis model, which showed the exterior columns buckling and losing their capacity to support the loads from the structure above. In Stage 3, the acceleration decreased as the upper portion of the north face encountered increased resistance from the collapsed structure and the debris pile below. NIST admitted that 7WTC achieved gravitational acceleration, or free fall, for 2.25 seconds. That is 2.25 seconds with the lower part of the building offering ZERO resistance to the upper part. Any resistance whatever slows the rate of descent. It is the law of conservation of energy. Also, picture the main towers. Huge steel pieces were ejected horizontally and caused to damaged or became impaled in a building across the street. Consider the resistance the lower portion must have exerted in order for the requisite horizontal force to have been achieved. I have no clue what mechanism could have caused what was recorded for all time on 9/11. A building cannot achieve gravitational acceleration (free fall) in collapse unless there is some force, in addition to gravity, applied. The lower portion of the building will not offer ZERO resistance. One can visibly observe, while the two towers fall, huge clouds of whatever (dust, powder, very fine particles) being formed. Assume one floor crushed the next floor to dust. Now calculate the force required to do that. The bottom floor must offer enough resistance to get crushed or pulverized rather than just move out of the way. Any energy expended on anything but accelerating the upper part downward slows the rate of descent. The initial theory of pancaking of floors was abandoned as physically impossible. The NIST theory ends at collapse initiation. No theory explains how the buildings came down in the precisely measured times, or how any achieved free fall, without repealing the laws of physics.

No theory would also include "controlled demolition" theories. Many things happen in nature which there are no readily available explanations for. But they happen. Anybody around WTC 7 could see it was going to fall from the damage it obtained. No conspiritard theories are necessary.
Large chunks of rubble, which were in free fall, were clearly falling faster than the rest of the twin towers.

"Other than initiating the fires in WTC 7, the damage from the debris from WTC 1 had little effect on initiating the collapse of WTC 7."

FAQs - NIST WTC 7 Investigation
11. In a video, it appears that WTC 7 is descending in free fall, something that would not occur in the structural collapse that you describe. How can NIST ignore basic laws of physics?
