It's a movie!

Yep, and a very well-done one at that.

All the actions depicted onboard the aircraft are speculation.

Not all. They have the results of 20+ phone calls made from the plane.
They know what was being planned.

There may be some factual descriptions about what was happening with ATC
and NORAD as NPR has been reporting all weekend that the actual people
portrayed themselves in those roles.

Yes, ATC has the real-deal ring of truth. What's really nice is that
they don't dumb it down or explain everything. If you understand
ATC-speak, you "get it" -- if you don't, it's probably gibberish.

It didn't seem to bother anyone in the theater -- but it sure added to
our movie experience, and I really appreciate the fact that the
director did it that way.

Best of all, they made the movie based on the actual timeline of
events. Things unfold at precisely the same pace that they did on
September 11th, which really gives it an authenticity it would not
otherwise have.
