Factual error: The "NY" tail markings on the fighter jet denote an F-16 model based in Syracuse, NY. Yet the plane is an F-15, of which Syracuse has had none. (00:13:05)
Factual error: Will Bailey (son of the Supreme Commander, NATO Allied Forces, Europe, and an Air Force officer himself) states the fighter jet alongside Air Force One is an "F-16 Falcon", but it is actually an F-15 Eagle. (00:13:05)
Factual error: The fighter jet alongside Air Force One has "NY" tail markings which designate it's with the 174th fighter wing, with a home base of Syracuse, New York. Surely, in this emergency over Washington, DC, jets from a more local base (like the 113th's F-16s at Andrews AFB) would have been dispatched to aid the President's plane. (00:13:05)
Factual error: At the end of the episode, the pilot says their runway has been changed to "runway 39." Runway headings are multiples of 10° from 01 up to 36. There cannot be a "runway 39."
Continuity mistake: Toby and Leo are in Leo's office talking about the friendly fire incident - Leo's glasses are sitting on his desk in front of him. He then picks them up and moves them to the far left. A couple of shots later, he picks them up from the right and puts them on.
Chosen answer: A really annoying innate lack of sense. My friends and family say the same thing all the time, and I'm endlessly trying to correct them. I think people just don't know any better and (ironically) couldn't care less that they're speaking incorrectly.
