Why and How the Twin World Trade Centers Towers Collapsed

Why 19 terrorists would hijack four airplanes and kill so many innocent people may eventually answered by our government leaders and physiologists as they identify and track down those behind these horrific attacks.

Understanding why the World Trade Center Towers collapsed following the impact and fires caused by the commercial airliners that hit them will be explained by forensic engineering and failure analysis that civil, mechanical and materials engineers will use in the investigation. These photos and the links to the CNN interview of blast expert Tod Rittenhouse and NBC's interview of twin towers project engineer Hyman Brown are posted so that you might better understand why the towers collapsed.
