Of course, the outcome is predictable; but the movie does well in its portrayal (or speculation) of what happened. Based on the documented telephone calls from many of the passengers to their loved ones on terra-firma, the movie does lend authenticity to the events as they unfold.
As most people also will say, I remember exactly what I was doing when 9/11 took place. And having two sons in the military; one a pilot who was scrambled, albeit not in that specific area, and the other working in The Pentagon that very day, I have a very vivid recollection of the precise sequence of events. Nevertheless, I still found the movie to be gripping, and even suspenseful, considering the premise.
