Factual error: A 747 allegedly Air Force One is shown taking off. But it is painted white, not the shades of blue as the real Air Force One is painted.
Factual error: Secret Service Agent Miles salutes the President inside of Air Force One and has the other hand on her hip. Secret Service agents do not salute. They are not military.
