Inside The Twin Towers is a 2006 Emmy award winning TV documentary (broadcast by both the BBC and Discovery Channel) which uses CGI effects and reenactments to recreate a minute by minute account of what happened on September 11th 2001 from the perspective of those who were inside the two towers at the time of the attack. The documentary is also known as 9:11: The Twin Towers.
The film follows the stories of a several people inside the towers, some of who survived the attack and escaped the tower, others who died. Particularly moving are the interviews with the survivors who you sense almost live with guilt that they made it whilst others did not. Another documentary which focuses on the experience of those inside the towers at the time of the attack is the 2011 History Channel feature Voices from Inside the Towers.
