Corrected entry: After Doug has finished moaning to his friends about not getting into the air force, his girlfriend can be seen in the background smiling. This is a bit out of character I would think. (At first I thought she might have been smiling at the voice on the PA but the voice is obviously Knotchers, whom she despises).
Corrected entry: 45 minutes into the film, Colonel Masters is berating his son, Doug, for pulling unauthorised maneuvers, as they flew in an F-16. Doug says, "Come on dad!" His father replies, "Don't 'Come on me' Dad" instead of "Don't 'Come on dad' me".
Corrected entry: It is impossible to fire a missile or rocket from an F-16 while it is on the ground. They do this while he (Doug) is on the ground rescuing his dad.
Corrected entry: As a former F-16 avionics troop one glaring mistake is the fact that munitions, i.e. missiles, cannot be fired on the ground. There is a switch called a WOW Switch. (Weight On Wheels) This switch will not allow weapons to fire when the landing gear is down.
Corrected entry: The helicopters Chappy and Doug engage soon after going feet-dry are Bell AH-1 Huey Cobras. As far as I know the USA is the only country that operates Huey-Cobras.
