Amy, I too am so sorry to hear your story, and this film deals with all of the events of the morning -- New York and the planes that struck the towers is the first half of the film, so you might do well to stay away from it.
Juan, it actually doesn't really dramatize them per se, it just shows them in a docu-style -- many of the "actors" are the real-life air traffic controllers who played the same roles that day, as well as actual pilots playing pilots, the head of air traffic plays himself and it was his first day of work. It's a great "performance" he does, must have been something to relive.
