Alcuni estratti:
The absence of peer review for the NIST reports is alarming, especially in view of the consequences of 9/11. These consequences include the preemptive wars that have led to a devastating loss of life and property and to a substantial refugee problem. Additional consequences include the imposition of mass surveillance and the erosion of civil liberties, as well as a need to resolve fire safety and building code issues.

Ironically, the very seriousness of NIST’s ethical failure in omitting meaningful peer review has resulted in a thorough, but non-official, independent peer review of the NIST reports. At the present time, over 2800 highly qualified scientists, engineers, and architects, as well as many other scholars, have examined the official account including the NIST reports and have found it to be in violation of the scientific method and the norms of genuine scientific research [12,19]. For example, as stated previously, the NIST investigation never examined the actual fall of the Twin Towers, nor did it examine the building remains for explosives, as required by the NFPA (National Fire Protection Association) guidelines in case of catastrophic collapse [20]. Independent analysis of the physical evidence, including the WTC debris powder or dust, points to the controlled demolition of the three buildings cited above [21]. For example, a very high percentage of iron-rich micro-spheres found by R.J. Lee group, USGS (U.S. Geological Survey) and others in the powder indicated the use of thermite, a substance that can have both incendiary and explosive properties [22,13].

[Qui sopra se ho capito bene sta parlando dei rapporti precedenti a quello del 2008 sul WTC7, quella che segue invece è la parte su quel rapporto]

Such an open process occurred during one of the public input sessions held by NIST in 2008, with startling results. NIST had invited public comments on its preliminary findings on why WTC7 collapsed. In responding to a comment by David Chandler, Shyam Sunder, the lead NIST investigator, claimed that in NIST’s structural model the visible portion of WTC7 fell for a distance equivalent to 17 floors in 5.4 s, which is 1.5 s or 40% longer than a time of 3.9 s that would be the case for free fall [23]. NIST had stated previously that this is “consistent with physical principles.” In his comment, David Chandler, a high school physics teacher, pointed out that a variety of methods showed from the motion of the top NE corner of the building that there was in fact free fall. Chandler’s measurements indicated free fall for the first 2.5 s, equivalent to a distance of 8 floors or about 30 m [24]. However, NIST did not acknowledge this fact. As Shyam Sunder had previously stated: “[A] free fall time would be an object that has no structural components below it. […] [T]here was structural resistance […] in this particular case.” Later, NIST simply incorporated a value of 2.25 s of free fall, based on its own measurement, into its final report without comment and quietly removed the statement about its analysis being “consistent with physical principles.” By failing to address the implications of freefall, NIST’s final report, in this context, has all the earmarks of attempted scientific fraud [25].

In altre parole un professore di fisica delle superiori ha DIMOSTRATO al NIST che l'edificio è caduto per i primi secondi (per 8 piani) come se non trovasse alcuna resistenza dai piani sottostanti... il NIST a quel punto ha corretto il suo rapporto segnalando la cosa... ma SENZA commentarla. In altre parole non ha volutamente spiegato come questo sia possibile.

L'articolo continua con molte altre segnalazioni sulla scorrettezza scientifica del NIST e su quanto sia difficile far pubblicare studi e ricerche che contraddicono la versione ufficiale per via delle implicazioni politiche della cosa... ma se volete potete leggervi il belink da soli.
