A look at those who witnessed the largest terror attack in history. 102 minutes passed between the first plane's impact into North Tower of the World Trade Center on 11 September 2001, the second plane's attack on South Tower, and the collapse of both buildings. During that time, people around New York reached for their cameras. This documentary joins together hundreds of pieces of footage and audiotape into a single, seamless historical record, much of it never seen before.
