Don, back to 9-11, this time to the pyroclastic dust and the effects of the dust on those who were at the WTC. newscientist.com > The extent of air trapping was found to reflect the amount of time each worker was exposed to the dust and debris of the buildings’ collapse. The most likely culprit behind this type of airway disease is pulverised alkaline cement<< Pulverised alkaline cement, but no-one asks how the collapse of a building can pulverize the cement sufficiently finely to cause a dust inhalation problem? However, some of us already know the only way this can happen is if the concrete had been subject to the compressive and destructive forces of an explosion. 911-strike.com >>A study by Paul J. Lioy et al. examined three samples of dust deposited by the WTC disaster, and found that the samples consisted of a homogeneous mixture, primarily made of cement and soot (37 to 50%), glass fiber (40%) and cellulose (9 to 20%). The proportion of particle sizes from 75 to 300 microns in diameter ranged from 42% to 46%, while particles less than 75 microns in diameter made up 30 to 39 percent of the samples. This dust was deposited around Manhattan in tremendous quantities (up to 10 cm thick at distances of 700 meters from the collapse site), consistent with the idea that most of the concrete, drywall and fireproofing in the buildings ended up as dust. Creation of such a finely ground and homogeneously mixed debris is difficult to explain as the result of a mechanical pounding process, but could be explained by highly turbulent combustion effects at high temperatures -- at least hot enough to cause spalling of the concrete due to explosive evaporation of entrapped water. ---------- When all is said and done, I believe that the analysis by Jim Hoffman is substantially correct -- the energy required to heat this huge mass sufficiently to reduce it to powder is very difficult to account for by any reasonable combination of gravitational and combustion effects, without the input of additional energy from explosives.<<
