"We are unable to provide a full explanation of the total collapse". - NIST September 27th 2007
As has been pointed out in this forum previously on a number of occasions, that is a reference to the difficulty in modeling the chaotic nature of the collapse post initiation. It should never be taken as any sort of concession to the notion that there's any doubt about the parts of the collapse NIST does describe.
For those here who're unaware of this reference: Steven Jones, Kevin Barrett, Richard Gage, and two victim's family members submitted a
request for correction/comment to NIST regarding what they characterized as problems with the
WTC collapse report, specifically that it violated the
Data Quality Act and
NIST’s "Guidelines, Information Quality Standards, and Administrative Mechanism" (referred to as the "IQS" in their petition). NIST responded quite directly, but as is habit with conspiracy peddlers, various elements of the response have been divorced from context and presented to mean something other than what it meant. The above quote is representative of that. If you read the response, you'll see that the sentence is actually limited in scope. Here's the surrounding context:
Catherine Fletcher of NIST said:
The final section of your request asserts that the WTC Report's stated goal and overall analysis violates the Data Quality Act and OMB/NIST Information Quality STandards. The basis given for this assertion is that NIST did not fulfill its responsibilities under the NCST Act because the focus of the investigation was on the sequence of events from the instant of aircraft impact to the initiation of collapse for each tower. The NCST Act, as you note in your letter, requires NIST to "establish the likely technical cause or causes of the building failure." In the case of the WTC Towers, NIST has established that the failures initiated in the floors affected by the aircraft impact damage and the ensuing fires resulted in the collapses of the towers. This conclusion is supported by a large body of visual evidence collected by NIST. Your letter suggests that NIST should have used computer models to analyze the collapse of the towers. NIST carried its analysis to the point where the buildings reached global instability. At this point, because of the magnitude of the deflections and the number of failures occuring, the computter models are not able to converge on a solution.
Your letter contends that NIST's report violates the Information Quality Standard of "utility". NIST believes that the report has utility. In fact, the codes and standards bodies are already taking actions to improve building and fire codes and standards based on the findings of the WTC Investigation. As mentioned previously, we are unable to provide a full explanation- of the total collapse.
I bolded the response sections important to this discussion. As I said above, the statement of being "unable to provide a full explanation" is in reference to the charge leveled that NIST did not continue to model after the collapse started. It is an exasperated reiteration of a point made in a previous paragraph. It is
not any sort of admission that the study is lacking. If nothing else, the statement is a scolding of any assertion that it is, since such modeling would not provide consistent answers each time.
We can all see that it is not honest to quote the above sentence without reference to the context in which the sentence appears. As far as NIST is concerned - as well as most reputable researchers - the goal of the Act authorizing the study was reached: The reason for the collapse was determined. That events past that point was not dealt with is only of concern to the conspiracy minded, as no one besides them sees anything suspicious in the events after collapse initiation.
At any rate, it's important to see how many elements of the 9/11 fantasies are taken out of context, and often carry meanings quite different from the ones the conspiracy peddlers try to assign to them.
