the many commercial products within that range fall into certain
categories or types--namely, dynamites, water gels, emulsions, and
fertilizer (e.g., ANFO) products. We are concerned, however, that the
court may not have understood that within each type there are numerous
commercial products meeting the 14,000-15,500 feet per second range.
Second, Williams testified that the VOD of water gels and emulsions are
just a tad on either side of that parameter of detonation [14,000-15,500
feet per second]. This testimony was incorrect. There are several
commercially available water gels and emulsions with VODs within the
14,000-15,500 feet per second bracket. See Dupont at 71; Dyno at 1-2.
Third, Williams testified at trial that he could rule out some of the
explosives that met the range--namely, the emulsions and the water gels
because of a failure to find microballoons and tipper ties in the debris.
Williams contradicted this testimony at his OIG interview.
As for the microballoons, if used they may have been made of resin and
likely consumed in the blast. More fundamentally, however, any
microballoons used would have constituted only about five percent of the
total explosive mixture. No residue of the main explosive was recovered
at the Trade Center. If residue of the component constituting ninety-five
percent of the charge was not recovered, it should be no surprise that
remains of the five percent component were not found. Williams
conceded at his OIG interview that the failure to find the microballoons
meant only that it's possible that they were not there. Williams added, I
couldn't eliminate them, because we didn't find anything.
Similarly, the failure to find tipper ties did not rule out water gels.
Williams testified at his OIG interview as follows:
OIG: Just because you didn't find tipper ties does not really rule
out those explosives, did it?
AGENT WILLIAMS: No, it does not. It would not rule it out.
If the explosives were shucked of all of their wrappers,
