The US Department of Homeland Security has bought an entire town in New Mexico for anti-terrorist training. There is a BBC report here:
http://news.bbc.co.uk/1/hi/world/americas/3693366.stm.

The person in charge of this project is Van Romero, Vice President of New Mexico Tech. Shortly after the events of 11th September 2001, Van Romero stated that he believed that explosives planted inside the World Trade Center towers had been the cause of their collapse:

He had been in charge of the Energetic Materials Research and Testing Center at New Mexico Tech.

Romero is a former director of the Energetic Materials Research and Testing Center at Tech, which studies explosive materials and the effects of explosions on buildings, aircraft and other structures.

But soon afterwards he retracted his statement:

He and his institution seem to have been well rewarded since:
Van Romero Appointed to National Panel on Education
New Mexico Tech Vice President Romero Named a Top Lobbyist
VP Van Romero Named Chairman of Domestic Preparedness Consortium
NM Tech VP Romero Receives Distinguished Public Service Award
New Mexico Tech Vice President Romero Named To "Players" List.

Explosives expert Van Romero says: "My opinion is, based on the videotapes, that after the airplanes hit the World Trade Center there were some explosive devices inside the buildings that caused the towers to collapse." The collapse of the buildings appears "too methodical" to be a chance result of airplanes colliding with the structures. [Albuquerque Journal 9/11/01] However, Romero, who says he was on his way to the Pentagon to seek Pentagon research funding when the attack hit, reverses his stance 10 days later. [Albuquerque Journal, 9/21/01] Might his need for government funding have played a role in his change of heart?
