In the first paragraph on p. 4 of a letter from NIST to Steven Jones, Kevin Ryan, and some 9/11 family members, NIST says the following:
"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 we mentioned previously, we are unable to provide an explanation-of the total collapse."
So the 9/11 conventional wisdom, the "man on the street" would tell you that the twin towers fell because of fire caused by being hit by planes full of jet fuel. However, NIST--the National Institute of Standards and Technology, part of the Department of Commerce--will not say that. NIST says they don't know why the builidings collapsed.
9/11: What we thought we "knew"
So another federal agency screws up the official 9/11 myth. Let's see where that leaves us:
1. Fire and jet crashes did not cause fall of Twin Towers (NIST)
2. Osama bin Laden did not "commit" 9/11 (FBI)
3. All high-altitude cell-phone calls on 9/11 were impossible (FBI)
4. Barbara Olson never reached Ted Olson on the phone (FBI)
Very interesting, yes?
