One of the worst productions in NOVA's history. The source of the animation used to depict how the buildings collapsed is far too close to the Bush administration and completely one-sided. There are no alternative theories, and the science and engineering conclusions make no sense in the real world. Nova has simply followed the dictates of what the National Science Foundation and the government have approved and sanctioned. There were many glaring omissions from the program; first, why did the buildings collapse at free-fall speed, that is, less time than it takes an unimpeded object to fall the height of the building? The smoke of the fire was a tell tale sign that the fires were not hot enough to melt the massive beams of steel used to construct the building. Nothing is mentioned about the heat generated nor the massive amounts of asbestos and cement dust that eventually caused so many emergency workers to lose their health. And, nothing at all is mentioned about Building 7, the building that supposedly housed the mayor's emergency headquarters, SEC records, and many other important government offices. Even though the building was only hit by spurious pieces from the nearby collapse of the twin towers, many hours later it too collapsed at free-fall speed, just like a planned demolition. This was one of Nova's worst moments.
