steel samples

Letter to NIST

I, together with two other individuals (a Doctor of Political Sciences and a Senior Engineer), yesterday submitted the following to a number of NIST personnel, including lead investigator S. Shyam Shunder, who in 2006 said to New York Magazine "But truthfully, I don't really know. We've had trouble getting a handle on Building No. 7". The contact information used can be found at the end.

The idea was mainly to remind them that there are people who will be looking at their report (if they come up with a report one day) with a critical eye.

Dear NIST investigators,

we undersigned wish to pose a few questions and comments to NIST regarding the still ongoing WTC 7 investigation.

NIST has stated that "no steel was recovered from WTC 7". This is clearly not accurate. FEMA has noted, e.g., that a steel sample from WTC 7 had undergone thinning due to "high temperature corrosion due to a combination of oxidation and sulfidation". FEMA continues: "Evidence of … oxidation and sulfidation with subsequent intergranular melting, was readily visible in the near-surface microstructure." Please see
