<<< IMO, the whole concrete dust speculation is a red herring. The concrete in the floors of the buildings was not structural, but a light weight mix that basically just provided a cheap and easy way to make flat floor surfaces. It was not the 3000 psi, 5 bag mix stuff used for load bearing foundations. I've never worked with it personally, but I assume it would give you something along the lines of pumice that would be fairly light and crumbly. I doubt it'd take much to turn it to powder as it was only designed to support the weight of desks and people walking across it. Between the drywall and light weight concrete, I don't think it's too hard to account for the dust, or even the fineness of the dust. >>>

Correct, correct, correct. A red herring indeed. The fact that some of the conspiracy theory crowd can't let go of this is proof to me that their thoughts on the entire topic of 9/11 should be ignored. If they can't grasp a simple explanation such as this, why trust anything else they post?
