Controlled demolition hypothesis for the collapse of the World Trade Center - Wikipedia, the free encyclopedia Quote: History Controlled demolition hypothesis proponents cite mainstream news reports on the day of the attacks that suggested explosions and secondary devices. Journalists and experts commenting on the events as they happened speculated that the World Trade Center collapses were caused by intentionally planted explosives. ABC News anchor Peter Jennings said "Anybody who ever watched a building being demolished on purpose knows that if you're going to do this you have to get at the under infrastructure of a building and bring it down" While watching footage of the collapse of WTC 7, CBS News anchor Dan Rather said "For the third time today, its reminiscent of those pictures we've all seen too much on television before when a building was deliberately destroyed by well-placed dynamite to knock it down." Some of these suggestions would later be retracted or revised. In a notable example, the Albuquerque Journal quoted Dr. Van D. Romero, an engineer who said that the collapses looked "too methodical" and that "some explosive devices inside ... caused the towers to collapse," speculating that the collision of the planes into the towers was a diversionary attack intended to attract emergency personnel to the scene, followed by the detonation of "a relatively small amount of explosives placed in strategic points" of the towers as the primary attack. He soon withdrew this assessment and later said he had been misquoted: "I only said that that's what it looked like." Engineers were in fact initially surprised by the collapses and at least one considered explosives as a possible explanation. The broad outlines of an explanation that did not involve such explosives quickly emerged, however, and took its current shape in the 2005 NIST report.  It has come to be known as "the official account" among proponents of controlled demolition. The hypothesis has gained support in part because engineers were unable to explain how the falling sections passed through the undamaged building beneath, bringing the towers down quickly and completely. I certainly understand what this means. We have a virus that must be acknowledged and neutralized.
