John I'm no expert but have been involved in demolition. So I got experience. Enough experience to know what your saying is just plain garbage.
Steel buildings imploded don't come down primarly by explosives. Demolition takes months to prepare because the infrastructure needs weakening. Columns cut, braces removed etc. You simply cant do that in a live occupied building on that scale without a huge amount of suspicion.
Secondly explosions aren't random, or a few big ones in controlled demolition. A building like WTC7 to be succesfully imploded into its own footprint would need to have mulitple, mulitple explosions going of a relative intervels. We all have seen footage of WTC7 collapsing and of cause no such explosions are heard, in fact no explosions at all just prior to the collpase.
... and dont give me this tripe about thermite. Its even more problematic, overt, cumbersome etc than explosives. To initiate that process in a burning building is beyond absurdity.
