It is Dustification!

This is so bizarre I almost wonder if it is a parody. Some middle-aged guy in a suit buys two concrete blocks at Home Depot, drops it off his 5th floor balcony, and then proclaims (surprise!) that 9/11 must be a conspiracy because it wasn't pound into dust. Of course possibly if he had dropped an acre-sized 4 inch thick concrete slab out the window, and then 100,000 tons of structural steel on top of it, he might have had different results? Anyway, this is one of those theories that is so silly, because even if they are correct, it is meaningless, as supermagiconanothermite would not cause a different effect, unless somehow we are to believe that the conspirators, for no particular reason not only rigged the supporting structure of two 110 story buildings and WTC 7 with explosives, but also went to the point of rigging the floors, just to pound the concrete into finer pieces. And the reason they would do this exactly is....
