There are moments and events that forever change our psyche and the way we view the world. There are days that begin like any other, but end in crisis. These are the events we must learn from, lest they be repeated. This engrossing and highly recommended series examines the cause and subsequent effect of each crisis - from looking at the social and political climate at the time, to examining how each event has changed the world - whether through legislation, preventative measures or other means. This program focuses on September 11th.
