That is apparently FALSE for that building. Where did you get this exactly? Please give us some cites. I hope it was not from NIST, or maybe they are more ignorant than ever imagined. This was a 40+ year old design building which was erected using precut, predrilled, prefab beams which were riveted onsite. There were few welds. The welds that were there were largely gas arc welds using alloy which was different from the beam alloy.

That would only happen if beams were flame cut onsite and not prefab. And even if there were lots more welds than suspected, the welding rod alloy used would not be the same as the unique beam alloy, which was special. > AFAIK he made *no* *effort* to rule out > that possibility.

Or -- if you do have real citations, please offer them. Steven Jones did seem to go off on tangents early on (he should have avoided building 1 & 2 altogether), but now that he has the support of over 400 top level architects and engineers, some even employed by NIST who were removed from this report because of their affiliation with him, many of the lose ends are being tied up. In fact the iron microspheres are less important than the other thermate-specific chemicals found. This site has many of the technical articles: http://www.ae911truth.org/#techarts Jones
