Why the towers fell. PBS is airing a special episode of Nova about the science behind while the World Trade Center towers collapse. Nova's reputation for converting esoteric science & engineering into understandable explanations for the layman should make the show something to watch. 7PM EDT/PDT on most PBS stations.
