The Debate on WTC7 Collapse: A Scientific Analysis of Explosive vs. Fire Theories

The collapse of the World Trade Center (WTC) 7 building on September 11, 2001, has been a subject of intense debate and multiple theories, with some claiming it was a case of controlled demolition while others assert it was a result of fire damage. While some figures from the engineering and demolition industries support the controlled demolition hypothesis, the National Institute of Standards and Technology (NIST) has consistently maintained that the collapse was due to extensive fire damage. This article provides a scientific perspective on why the 'controlled demolition' theory is unsupported and why the 'fire damage' hypothesis stands as the extant and un-falsified hypothesis.

Established Scientific Hypothesis: Fire Caused WTC7's Collapse

From a scientific standpoint, the event in WTC7 is often referred to as the "extant hypothesis," which means it is the current working theory—a hypothesis that has not yet been proven false. The hypothesis that 'fire did it' (i.e., the extensive fire damage caused the collapse) has never been successfully challenged by any evidence to support the 'controlled demolition' claim. No claim has been able to provide experimental evidence or a plausible mechanism to show that controlled demolition played a role in the collapse of WTC7 or the other WTC structures.

Analysis of Controlled Demolition Claims

Those advocating for 'controlled demolition' (CD) of WTC7 have not presented a coherent or scientifically valid hypothesis. The contention that the collapse could have been due to controlled demolition has not been corroborated by any piece of evidence that can falsify the 'fire did it' hypothesis. Instead, it remains a hypothesis that is yet to be substantiated by any robust experimental evidence.

Why 'Hundreds of Engineers and Demolition Companies' Are Wrong

It is crucial to clarify that the assertion that 'hundreds of engineers and demolition companies' support the controlled demolition hypothesis is a misrepresentation of facts. Firstly, many demolition experts and companies have publicly dismissed the controlled demolition claims as entirely baseless. Secondly, even the few individuals, such as Danny Jowenko, who have shown support for the WTC7 'controlled demolition theory' have not provided any substantial evidence to support their stance. Their statements are often contradictory and lack the necessary context to validate their claims.

Georgia State Munitions; A Blast Loader Not a Demolition Expert

For instance, Tom Sullivan, a blast loader, hardly qualifies as a demolition expert. His role is typically to execute the physical tasks of loading explosives, a task that does not require specialized knowledge of the mechanisms of controlled demolition. Similarly, former military personnel who have used explosives but have not performed controlled demolition are not qualified to comment on such complex engineering theories.

Critical Examination of the AE Petition Signatories

The 'AE Petition' signed by 2500 engineers has been significantly hyped as evidence of widespread support for the controlled demolition theory. However, when examined closely, the validity of this claim is called into question. The global population of engineers is approximately 25 million, so the fact that only less than 0.01% have signed the petition is far from an overwhelming endorsement. Further, many of the signatories are architects, who, due to the nature of their training, often have limited knowledge of high-rise structural engineering. Additionally, a significant portion of the signatories are in fields unrelated to the events of 9/11, rendering their opinions largely irrelevant to the specific circumstances of WTC7.

Peer-Reviewed Expertise Over Public Petitions

When looking at structural engineers with relevant postgraduate qualifications, the numbers are even more revealing. Counting only those with PhDs in structural engineering, the number is in the single digits, not the thousands as claimed by petition proponents. In contrast, the NIST panel includes over 200 world-leading experts on high-rise collapse, many of whom are independent contractors who contributed to the development of the NIST report. The analogy of choosing life-saving medical advice from 200 neurologists over 2000 proctologists without access to patient records effectively illustrates the disparity in the quality and relevance of expert opinions on this issue.

Conclusion

From a scientific perspective, the 'fire did it' hypothesis remains unchallenged and stands as the evidence-based explanation for the collapse of WTC7. Any claims of controlled demolition for WTC7 or for other WTC structures remain unsupported by experimental evidence or a logical mechanism. It is therefore imperative to recognize that the 'hundreds of engineers and demolition companies' who support the controlled demolition theories are, in fact, wrong in the context of established scientific methods and evidence. NIST's report, whether entirely accurate or not, does not need to be proven wrong to maintain the 'fire did it' hypothesis as the current, un-falsified explanation for the collapses.
