This film locks you in and holds onto you the entire production. It gave me a completely different view on what really occured on that ominous day in history. It also gave me a whole new respect for the heroes of that day, and the firefighters who risk thier life every day for us. The hairs on my neck stood up several times due to the realism of the live footage. Highly recommended. Proably THE best inside look from the ground up on 9/11. Extremely well done. Truly a must see for everyone.
