I did a load of really rough calculations last year on this thread and came up with about 16 metric tonnes per floor, and that is after considerable preparation of several weeks. The towers collapse was hardly clean and destroyed or damaged several other buildings in the vicinity, so i would not suggest it is a viable method.So what size explosives would've been needed to create enough structural damage to a floor to knock off the fire proofing and create an office fire that could cause total collapse. What's always intrigued me about the towers is most people talk about controlled demolition when taking down a building, but we saw for the first time in 3 seperate cases where a destroying and weakening a few floors actually caused total collapse. So can a big enough bomb cause the same outcome? And if so, isn't it cheaper and less time consuming for demolition companies to use this method in the future instead of wiring and cutting the entire bldg.
Danny Jowenko, a demolition expert, didn't think that made sense because he didn't think explosives could survive the fires.
He is right, but DJ was duped by A&E into making a call out of context and he contradicts himself afterwards as a result. The explosives themselves are flammable.
