The most damning evidence that demolitions took place on 911 is the destruction on WTC 7. Take a look at the building's collapse below ...it was obviously destroyed by a controlled demolition ...the demise of building WTC 7 has also been methodically avoided by mainstream reporters and the press.
building WTC 7
...doesn't this look like someone "let the air out" and "deflated" WTC 7? Buildings just don't fall down like that without a lot of help from strategically placed explosives.
If all it took to bring a skyscraper straight down was a fuel fire, the well trained experts who work for demolition companies would all be out of a job. Come on, even a layman with no explosives background should be able to see this.
Many specialists in the explosives and structural engineering have also made this observation and commented on these inconsistencies. After the WTC collapse, the Vice President of New Mexico Tech, Van Romero, gave an interview to the Albuquerque Journal. Romero, an explosives and demolitions expert, stated plainly that he believed that the WTC collapse was too methodical and that explosive devices must have been placed in key points of both buildings. Romero said:
"It would be difficult for something from the plane to trigger an event like that. It could have been a relatively small amount of explosives placed in strategic points. One of the things that terrorists are noted for is a diversionary attack and a secondary device."
In that same interview, Romero revealed that he was in Washington DC when the attacks took place. He and a colleague were there to discuss defense research programs for New Mexico Tech. A few days after his interview, Romero abruptly changed his opinion and told the Albuquerque Journal that he no longer believed that bombs brought down the towers.
...uh oh ...Romero, who relies upon the Pentagon for funding, had suddenly flip-flopped, he changed his mind and joined the "melted steel" theorists. Now why would he do that?
