The cell phone/air phone calls are an area of tacit fiction that the auteur fudges with discreet but significant treatment. The actual recorded calls from the "passengers" of United 93 are suspiciously vague and calculated. The calls were never more than a couple of sentences long and share a symmetrical brand of abstract logic that rings false in the context of a hijacked aircraft.
Transcripts of the "calls" reads like answers from a sixth grader cheating on a test he doesn’t know the questions to.
"It’s bad news. I need you to be happy."
"Ted, what can I do? What can I tell the pilot?"
"We’ve been hijacked. He had an Islamic book."
"It’s getting very bad on the plane… the plane is making jerky movements."
These examples taken, from the 9/11 Commission’s Report as referenced in writer/director Dylan Avery’s persuasive documentary "9/11 Loose Change," are telling for their clipped structure and ridiculously short length. They don't convey any of the mile-a-minute patter that a panicked person would use to call for immediate help in a hijack situation.

Ultimately, "United 93" is a regurgitation of suspicious media-fueled speculation about events on an airplane that we know very little about. This is a movie that does more to discourage raising questions about what really happened to flight 93 than it does to encourage debate over the bastion of lies that have been fed to the American people.
It is an interesting footnote that United flight 93 was not scheduled to fly on 9/11, and that the plane (tail number N5IUA) was spotted by United Airline’s employee David Friedman on April 10, 2003 at Chicago’s O’Hare Airport, and that the plane is listed as still valid with the FAA. Dylan Avery provided essential information used in this article in his documentary "9/11 Loose Change."
