Tom Sullivan (a member of ae911truth.org) worked for Controlled Demolition, Inc. for almost three years before and during 9/11 as a Site Photographer and Explosives Technician. He is also licensed by the FDNY to handle explosives. His explosives technician duties included placing explosives in buildings to prepare them for demolition. In this video he talks about the operations of a classic controlled demolition, including the wide use of Thermite self-consuming shape charges, the availability of remote detonation (which he suggests is too expensive for most applications other than military) and lack of steel casings, seen mostly in older jobs. According to Sullivan, one would expect a ‘wave of explosions’ whether then one large boom, just as multiple pieces of video demonstrate from 9/11. Sullivan called the NIST report on Building 7 “very suspect,” while pointing out that he speaks as an individual based on his experience with CDI (but not in any way on their behalf).
At the heart of Sullivan’s statement, he says:
“I knew from day one this was a controlled event. And why I did that was simply looking at Building 7. You have a sudden collapse of a building; it’s fairly symmetrical as it comes down. There’s a classic kink, which means the center core collapses first. You can see that on the video. And the building falls near freefall. So I really, honestly, didn’t believe this from day one, because this is the way buildings classically come down with controlled demolition.”
