"My degree and my expertise are in Explosives Engineering. I know of no way a building can collapse like that EXCEPT IN A CONTROLLED DEMOLITION."
I've looked into the building collapses and the logistics of planting the explosives would be practically impossible, but that doesn't stop people like Neidernut with his degrees and knowledge of civil engineering, chemical engineering, mechanical engineering, thermodynamics, physics, etc etc... Gee whiz that Harvard Education was all encompassing!
But the reality in Building 7 is besides the heavy fires and severe structural damage caused by the earlier collapses, is that just before Building 7 collapses there is not one tell tale of an audible explosion of what is needed in a genuine controlled demolition. In the following video of multiple angles of the Building 7 collapse some of the footage is accompanied by sound and the most striking feature is in the period directly before is the eerie silence.
And as for the WTC 1/2 collapses, to me they don't look very controlled and as Neidernut likes to guess, that the windows being blown just ahead of the collapsing floors is the result of explosives, which in reality is just the air pressure escaping as the inside air of the building is severely compressed and looking for a way out. And again just before the demolition of the twin towers, there would be massive explosions but all I can here is the sounds of the buildings collapsing.
In the seconds preceding the collapse, the weakened structure drastically bows inwards as the top floors collapse into the floors below and on and on it goes till the building was demolished.


BTW, there was no thermite or even nanothermite particles discovered at the scene, the only samples of microscopic red chips which I don't believe have been properly analysed, came from some Kooks!
