MUNSTER | An architect who questions the official story behind the collapse of the World Trade Center on Sept. 11, 2001, spoke to a receptive audience Monday night at the Center for the Visual and Performing Arts in Munster.

Richard Gage, founder of Architects and Engineers for 9/11 Truth, appeared at the behest of Liberty Straight Up, an activist group and social organization in favor of limited government. It has members who live in Lake, Porter and LaPorte counties.

Gage is on tour to promote his group's position that the fall of the World Trade Center in New York City during the Sept. 11 terrorist attacks had all the earmarks of a controlled demolition. Neither fire nor the impact of two airplanes was enough to bring down the Twin Towers, he said.

During a multimedia presentation, Gage said he was less concerned with the motives for the destruction and the people behind it than with what he said is the science behind the collapse.

“We want a new investigation that incorporates all the evidence,” he said.

The 1,500 architects and engineers who belong to the group have gone public with their concerns because "we're called to, and we care very much about our country," Gage said.
