LVI Services, the largest asbestos abatement company, based in New York City, was working for years in the World Trade Center. Above the ceiling panels, next to support beams, would be the perfect place to plant explosives under the cover of asbestos removal. LVI removed asbestos from the Pentagon as well. LVI serves the US Government on controlled demolition projects. The president of LVI, Scott E. State, has held numerous Top Secret clearance positions with the Department of Defense. He was not questioned before the 9/11 Commission nor was his company mentioned in the 9/11 Reports. www.LVIServices.com
