NIST Did Not Mention Swiss-Cheese Looking Steel Sample |

|
|
|

Whereas, the authors of FEMA Appendix C took the approach of calling for further research, since, for example, the rate of corrosion was unknown, NIST took the approach of saying, since it is unknown, the relationship between when the corrosion occurred, and the collapse can’t be determined. Furthermore, NIST noted the Appendix C authors stated they believed one of the steel samples came from WTC 7. NIST treated this as equivalent to the location being unknown, and it was not possible to link the first sample conclusively to WTC 7. Because of this, it wasn’t studied further. This explanation was provided in a letter dated June 24, 2010, from NIST Senior Communications Officer, Michael E. Newman, to Ronald H. Brookman. Mr. Brookman had written to NIST Director Patrick Gallagher inquiring on this and other matters, May 31, 2010. |
