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: 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."
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: In this episode, it is Inauguration Day in January. In the previous episode, when CJ is visiting her father in Dayton, Ohio, it is February, according to CJ (when she complains that it will be too cold to go fishing with her father).
20 Hours in America: Part I - S4-E1
Factual error: This show is supposed to take place in September, but the height of the corn and the complete lack of foliage change (even in early September there would be a little red or orange in the trees) make it look much more like June.
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)
20 Hours in America: Part I - S4-E1
Factual error: The President is campaigning in Indiana and Josh, Toby, and Donna get stranded there around noon - but the shadows are quite long and it is obviously not noon in real time, but perhaps mid to late afternoon.
Factual error: In the first shot after the recap, the overlay text reads "United States Capitol/Sunday/Inauguration Day". During this episode and the one that follows there is an inauguration day celebration and President Bartlet makes his inauguration speech. Historically, however, when inauguration day falls on a Sunday the celebrations and speeches are scheduled for the next day, a Monday. The president is still sworn in on inauguration day (March 4th until 1933, January 20th after that), but all other activities are moved back one day. The inauguration date has only fallen on a Sunday 6 times since 1798, and only twice since the current inauguration date was set, so it is understandable that this arcane but important bit of scheduling tradition was missed by the show's researchers.

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.
