NEW YORK, NY April 05, 2005 —Federal investigators today, will release their most-detailed analysis of why the World Trade Center collapsed.
Federal investigators have already hypothesized that the towers didn't fall because of their lightweight floors or insufficient fireproofing. Those factors may have played a role. But investigators have suggested that it was the impact of the airplanes and the resulting fires that caused the weight of the buildings to shift to their outside columns, bringing them down.
Today's report will offer a revised analysis, with the exact sequence of events. Investigators will also release reports on their interviews with first responders and survivors who were inside the towers. Later this year, they'll release a final report with recommendations for improving building design and fire safety.
