Determine the origin of the NanoThermite and iron microspheres found in the residue of the 9/11 2001 WTC buildings.

The current official US Government report on the events of 9/11/2001 does not mention the NanoThermite found in the building residue. Nor does the NIST report explain the origin of the iron microspheres also found in the building residue. These are important since they help explain how WTC building 7 (which was not hit by an airplane) collapsed in a manner similar to a controlled demolition which required hundreds of structural components be simultaneously destroyed. Office fires (as asserted by NIST) could not have caused this manner of collapse.
