This video, from Youtube, shows eyewitness accounts of bombs, supposedly, going off in the North Tower, South Tower, and WTC Building #7 sometime after the planes crashed into the World Trade Centers. According to the eyewitnesses and the media, these explosives, or "secondary devices" seemed to have gone off minutes before the towers fell, thus showing that the collapse of the towers and Building #7 was previously planned to be a controlled demolition.
This video, also from Youtube, goes into more detail to support the theory that the WTC's, and Building #7 collapsed due to bombs planted there. It, primarily, provides various hypothesis's (such as the "pancake theory") to prove the theory that the collapse was due to demolition caused by bombs.
Much of the evidence in this video were provided by physics professors and other specialists in the field of controlled demolitions and implosions. The first evidence provided by the video is the numerous eyewitness accounts of people hearing mulitple explosions prior to the collapse of the buildings. According to one eyewitness, explosions could be felt five blocks from the buildings. Next various professors specializing in the fields of physics and demolitions were asked to give thier opinion on the collapse of the buildings. One such theory was the aforementioned "pancake theory". According to this theory, bombs were, supposedly, placed on each floor of the core support struts in the builidngs. When the bombs were activated, the floors collapsed on top of each other like a pancake. Also, after the collapse of the two towers, no chunks of concrete was discovered. This was becuase the concrete was pulverized by the bombs. These along with many more convincing evidence shows that bombs might have caused the ultimate devise of the towers and Building #7.
There is something about conpiracy theories that seem to capture the attention of the American public. Could it be that in the desire to discover the truth, the public concieves theories about our goevernment creating these disasters? Or could it just be human nature and curiosity? The separate comments posted on each of these videos are interesting in that one set of comments counter's the other set. The comments posted on the "Bomb's planted in the WTC" video show that many people believe that the bombs were, deliberately, planted in the buildings. The comments on the "Were explosives used?" video shows people who think that this theory is bogus.
