These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: October Sky
Critical Research Failure: Homer writes a letter of condolence to Werner von Braun after the failure of the Vanguard launch. Vanguard was a Navy project that von Braun had nothing to do with, and one he actually opposed; he was part of the Army Ballistic Missile Agency, which successfully launched the Explorer satellite later that year.
In Homer Hickam's commentary, he points out that the equation Homer in the movie uses to show where rockets landed is the equation used to determine the height it reached during flight.
Executive Meddling: The title was changed from "Rocket Boys" because executives believed that having "Boys" in the title would drive away female viewers.
"Funny Aneurysm" Moment: The police come to the boys' school to arrest them for the forest fire. The Moment comes when the math teacher complains that the boys have been metaphorically put in handcuffs.
