Don't get me wrong, I'm on your side, but why do these so called scientists claim thermitic or explosive was found in the dust and some believe collapse was due to controlled demolition? I distinctly remember on that day, watching it live on TV, both towers tilted with the south tower doing so more. Clearly when the north collapsed you can see how the top portion above point of impact buckled before the rest of it came down.
Oh dang, I forgot about this. Spent all afternoon on ISF instead. Next opportunity for me is Tuesday.
There is a segment of society that believes in an extra-governmental, organized shadow entity that causes events to occur to further their own self serving and secret agenda.
To this segment of society all events are suspect of having been caused by this shadowy group.
Thus they look for any small unknown, any slight flaw in official explanations of such events and specifically work towards bolstering their preconceived expectation of these events.
In this case it takes on a myriad, a wide spectrum of, claims. From extraterrestrials, through undefined space based power beams, faked or switched aircraft, to preplanted explosives or incendiaries.
One group points to a study of the dust that concluded thematic material was part of the dust matrix. Another study was done refuting that claim. Which to believe?
To my mind, the quantity of thematic material claimed in the dust samples would require that an enormous, quite ridiculous, quantity would have to have been initially loaded into the structures. Bear in mind that this is unreacted thematic material, leftovers that did not contribute to the collapse. It is further claimed that the long lasting, very hot rubble pile fires were effected by , again, leftover thematic material that did not contribute to the collapse. This the begs the questions, "how much was actually loaded in?; how was it done unobserved?; why was the burning of such enormous quantities unobserved?; why the huge overkill margin?", none of which are not addressed or at best woefully insufficient.
Furthermore the supposed thematic material has never been tested for a particularly thematic property, does it self oxidize, burn in a non-oxygenated atmosphere?
