Underwriters Laboratory Fire Endurance Testing of World Trade Center Floor Truss Assemblies, September 21, 2005.
World Trade Center North Tower (Tower A) complete blueprints, dates ranging from July 1967 – February 1984.
We have discovered distinctive red/gray chips in all the samples we have studied of the dust produced by the
destruction of the World Trade Center. Examination of four of these samples, collected from separate sites, is reported in
this paper. These red/gray chips show marked similarities in all four samples. One sample was collected by a Manhattan
resident about ten minutes after the collapse of the second WTC Tower, two the next day, and a fourth about a week later.
