On September 11, 2001, the world watched in horror as New York's World Trade Center towers went from 110 stories to 110 feet high in a matter of seconds. The shocking destruction raised many questions: What caused the towers to fall? Why didn't they collapse right away, and why did they pancake down instead of toppling sideways? Following the disaster a documentary team was granted unique and exclusive access to Ground Zero and the Fresh Kills disposal/investigation sites. The result is After the Fall. This films documents the scientific, technological and engineering effort involved in unearthing the details of the collapse from beneath the rubble.
