Computer modeling at the University of Alaska Fairbanks shows how a building next to the Twin Towers came down on 9-11. The collapse simulation for World Trade Center 7 is part of a 4 year project conducted by UAF engineering Professor J. Leroy Hulsey, and 2 former graduate students, for the non-profit group: Architects and Engineers for 9-11 Truth. KUAC’s Dan Bross reports.
