Investigating the Collapse of WTC Building 7 - Essay Example

As a response to the criticism, NIST tried to provide a more technically advanced explanation of their initial proposed theory that explained the collapse of the tower's initiation while completely trying to remove the fault from the construction of the buildings. In their report, they stated that the impact from the planes dislodged the steel insulations, and due to this, the steel succumbed to extreme fires. Portions of the perimeter walls were then pulled by the sagging trusses, which caused rapid spread of the perimeter columns and made them unstable. In addition, contributed to the increased strain on the core columns, which had already been weakened by the extreme fires, lastly, the floors above the collapse zone produced tremendous energy that eventually led to the global collapse of the structure (The National Institute of Standards and Technology (NIST)).

With the above review of the NIST investigations final report, it is clear that their analysis was not confined within the perimeters requirements of engineering investigations since they exhibit exclusions and biasness in some of their research. Due to this, their explanations that mostly revolve around probable collapse sequence do not address any of the relevant issues since they steer clear of the main topics while also stopping at the critical moment of the buildings collapsing. With this, the report avoids explaining the overlap with the period in which the demolition-like features appear and the longer timeline of the truss-failure theory. Due to these loopholes within their explanations, it is right to state that their theory helps spark more questions and conspiracy theories on why the building collapsed rather than highlighting the facts like why the collapse had more characteristics of a controlled demolition which are not common in steel framed buildings as was the case of the WTC Building 7.

NIST's report on the event has been challenged as incorrect by many organizations that have viewed their explanations as eluding the truth of conspiracies and evident features of controlled demolitions in the building collapse. The independent organizations mainly challenge the NIST theory on its proposal of fire damage and crash effects as the main cause of the collapse, since they see no direct connection between the global collapse and the collapse initiation making the NIST report unrealistic. Architects & Engineers for 9/11 Truth is an example of an organization that is critical of the NIST theory. In their counterargument, they point out the fact that it is not possible for the WTC building to have fallen at the accelerated speed that was observed without having had several of its columns that support the structure of the building being torn apart by using strategically placed explosives ( The National Institute of Standards and Technology (NIST)).

For the Architects & Engineers for 9/11 Truth to support their claim they used free fall acceleration point to mid-air pulverization of concrete and lateral ejection of steel during the buildings collapse as their main explanation basis. In addition, their explanation clarifies the idea that due to the absence of large deformations that often form gradually during a normal collapsing process, it is clear that the building was without a doubt destroyed through controlled demolition. From this perspective, the fact that the three WTC buildings fell through what they term as the path, which should have had the greatest resistance further helps support their explanation of using controlled explosions to remove the critical columns, which could not have been achieved with fire as a medium.

Lastly, they state that the fact that the north tower’s top was blown outwards during the collapse left no other explanation for the building collapse if not from a controlled demolition from the inside. Some other evidence that the organization presents to support their case is for example the found un-ignited nano-thermite, which is known to be highly flammable and can be used on explosives. According to my view the credibility of the Architects & Engineers for 9/11, Truth organizations should not be in question considering the lengths they have gone to uncover the truth, I honestly think their voices should be heard since they might be on to some truth that others would want overlooked.
