Journal of 9/11 Studies Article: NIST and DR. Bazant - a Simultaneous Failure

The NIST enquiry into the destruction of the WTC towers purported to be an examination of the physical evidence. The final report includes commentary upon much of the physical evidence available from this examination but concentrates upon the time period prior to the onset of the collapse. The report does not go into much detail of the period of the collapse itself but instead relies upon the theoretical work of Dr. Bazant, to argue that once collapse was initiated then total collapse was inevitable.


Dr. Bazant has stated in his analysis, that his energy ratio would be increased in the event of early failure of the column end connections. This is correct and examination of the debris pile with specific regard for the numbered and identifiable columns from the area in and around the aircraft impact area could have given more precise information from a physical rather than a theoretical source.

The short cut taken by NIST in relying upon this theoretical work, allowed them to avoid a continuation of their examination to include the physical evidence available from the collapse. Such a continuation would have shown many points of evidence which cannot be readily explained by a collapse whose initiation and progression was caused as a result of aircraft impact and subsequent fires. It does however allow the authors of the NIST report to pass responsibility to Dr. Bazant for this, the most important part of the investigation.

A theory which can be so easily refuted is not an adequate foundation on which to rest the conclusions of a report on an event with such far reaching global consequences.

But since NIST relies upon the work of Dr. Bazant to justify their assertion that collapse, once initiated, would inevitably progress to ground level, this refutation of Dr. Bazant's work and theory also serves as a refutation of this most crucial part of the NIST report.

Very nice

2 letters and Article today! Busy day for the Journal of 9/11.

Great work. I admire the work of Gordon Ross.

Now if only we can churn out some simulations of the collapse....

Help me shout 9/11 articles on:

The biggest crime scene in an American history

WOW The biggest crime scene in an American history and they get rid of most evidence before a determination of why the buildings fell. Who made the decision to get rid of the evidence? Does anyone know?

I am assuming the city of NY

was in charge of the scene, unless at some point the FBI took over. Either way the nephew to the mob, mayor Ghouliani was the ringleader at the time. Im sure he was ordered to courdon off the area and remove the evidence, I doubt that it was his decision, but either way its a federal crime, and he was instrumental in the commission of that crime, which as a former prosecutor, he knew was a crime.

Physics/Science/Mathematics do not lie, only people do.
9/11 was an INSIDE JOB

Digg link..
"If I had just paid $20 million for the NIST report, I'd be asking for a refund!"
-Dr. Frank Greening

Just read the paper...

conclusion: Bazant = pwnt, therefore NIST = pwnt ^2

hows their building 7 paper coming along?

9/11 was an INSIDE JOB

Great article

This and the mathematicians' Letter together are a formidable response to NIST.

This statement by Ross stuck out for me:

"In a collision, energy is dissipated in both the impacting and impacted objects in proportion to their relative strengths, characteristics, and construction." (p. 41, second full paragraph)

This common sense notion prompted MIT collision experts to say:

To the casual observer, it would appear that the facade of the Twin Towers did not offer any resistance at all, and that the plane's wings and fuselage slice through the exterior columns as if they were made of cardboard. . . How was it possible that the relatively weak, light, and airy airframe damaged the apparently heavy lattice of high strength steel columns? The devastating result of this encounter came as a surprise to the engineering and scientific community or at least to the present authors.
