Oh heavens no, not from NIST, in fact there was no solid source involved
at all.  The bit about welding was just "common knowledge" and if WTC
1&2 weren't put together that way then it was just plain false.

My knowledge of the source for Jones's dust sample, OTOH, came from
reading a longish paper from Steve Jones on the subject of WTC 1&2.

OK, I didn't know any of that.  Sorry.

Former.  And, consequently, the latter too.
