As I recall; firefighters were interviewed of them stating that they heard the explosions.
Yeah, when thousands of tons of steel and concrete progressively collapse floor upon floor you're gonna HEAR what sounds like explosions. But no one reported they actually SAW an explosion.
Reason being is that explosives, such those commonly used for controlled demolition like dynamite or RDX, have detonation velocities in the neighborhood of 17,000mph, which is about the same velocity necessary to put a space shuttle in orbit.
Had there been such detonations on every floor as the building came down, in all that dust and debris, we would have clearly seen the blast waves.
Furthermore, in order for an explosive charge to sever a steel beam, the charge must be embedded in or attached directly to the steel.This would have required access to the steel and in order to do that, sections of walls, elevator shafts, air ducts, plumbing, electric cable shafts and conduit would have to have been removed. Then you have debris removal to contend with.
This work would have required power tools, air tools, gas and electric torches, and a wide variety of special tools.
Installing an explosive matrix on every floor is logistically and financially prohibitive for the simple reason it isn't necessary. The amount explosives and associated firing circuits including det cord and detonators would have been in the tons. The continuity of the electric or electronic firing circuits throughout the entire complex would have to have been checked, rechecked, and undisturbed for wh**ever time was necessary before detonation.
Before the explosives and associated wiring, sequence relays, and detonators are brought into the building, all electric power to the building would have to have been shut down and once the charges are in place, then the detonators are brought in and they would have to have been shielded against radio, television and high frequency t***smissions.
With such a complex and massive demolition matrix, the timing of the detonations in exact sequence would have required computer control.
Moreover, the impact force of a 130 ton jet flying at near 500mph has been calculated as equivalent to the detonation of just under a ton of TNT. The impact and subsequent fuel explosion and fires would have either detonated, burned or destroyed any demolition charges and firing circuits in the impact zone.
The notion that such a demolition matrix could have been installed in a total of around 260 floors over a total of nearly 3000 feet is ludicrous, the work necessary to accomplish such a feat would have taken a 100 man crew over six to nine months to complete. This could not possibly have been accomplished in complete secrecy.
I didn't spend hours on demolition contractors websites researching the process of setting up a controlled demolition and not learn anything. In fact, Protech Solutions, a company that specializes in commercial, industrial and medical facility demolition, published a detailed paper on the theory the WTC was destroyed through CD. They shredded that theory piece by piece. It simply did not happen.
Regardless of what firefighters or anyone else may have heard when those buildings came down, the belief that they heard the detonations of explosive charges is ridiculous.
But what really solidified it for me is the Architects and Engineers for 9/11 t***h video titled "The Experts Speak Out".
That is a mind blower, man, I mean seriously, for men supposedly trained and experienced in building design and construction to make some of the claims they made in that video is appalling. I could give you one example that stands out above all the others. David Chandler, a HS physics teacher with a BS in physics, and his case the BS doesn't stand for Bachelor of Science. He must have thought that everyone in his audience was a knuckle d**gging i***t. If you want to hear some real junk science, lemme know.
