I watched the most interesting video.
I wonder which design of nuclear device(s) were employed at WTC?

There were no dead passengers at the Pentagon, because there was no airliner there. Many dead congressional auditors, but no dead passengers, no landing gear or engines, no airliner, as reported by the soldier who walked through it all on her way out, April Gallop.
After the 9/11 attacks, international investigations were launched into financial transactions that seemed to indicate foreknowledge about the coming catastrophe.1 For its part, a technology firm named Convar, located in Pirmasens, Germany, had been tasked by the U.S. Department of Defense to restore data on damaged hard drives gathered from the ruins of the destroyed WTC skyscrapers. These investigations stemmed from suspicious and untracked transactions – up to 100 million dollars – carried out using WTC computers right before the attack, pointing to foreknowledge of the total destruction of the evidence.
Failure of Welded Floor Truss Connections from the Exterior Wall during Collapse of the World Trade Center Towers
Analysis of the connections supporting the composite floor system of the WTC towers showed that at and below the im- pact floors, the greater majority (above 90%) of the floor truss connections were either bent downward or completely re- moved from the exterior column. This was probably related to the overloading of the floors below the impact region after col- lapse initiation. Depending upon weld joint geometry, detachment of the main load-bearing seats was a result of either fracture in the heat affected zone of the base material (standoff plate detached from spandrel) or through the weld metal (seat angle detached from standoff plate). Failure in both cases was assumed to be a result of a shear mechanism as a result of overloading from floors above impacting those below. There did not appear to be a significant change in distribution of failure modes of the floor truss connections when comparing those connections inside vs. outside of the impact region or those ex- posed to pre-collapse fires and those that were not.
What Was in the World Trade Center Plume? [Interactive]
Ten years later, what exactly residents and rescue workers were exposed to remains at least a partial mystery
By David Biello on September 7, 2011
Ten years later, no one knows what was in the cloud of gases released by the combustion of all that jet fuel and building material but science has revealed what was in the dust—cement, steel, gypsum from drywall, building materials, cellulose from paper, synthetic molecules from rugs, glass fibers and human hair from the long decades of the two towers' use, among other items. "The [World Trade Center] dust held everything we consider near and dear to us," wrote Lioy, who carried out the first such analysis, in his book Dust: The Inside Story of Its Role in the September 11th Aftermath (Rowman & Littlefield Publishers, 2010).

Do you have physical evidence of columns cut to initiate collapse?
Don’t follow. If WTC dust didn’t come from WTC buildings, then where did the dust come from. Pixies? Dust bombs?
