Continuity mistake: In all of the aircraft scenes, almost every time they showed his aircraft, he has different types of weapons on it.
Continuity mistake: After Doug drops the Hades Bomb, the next scene shows his F-16 landing to pick up his dad. Look closely at the belly of the plane and you can see that the Hades is still there.
Continuity mistake: When Doug Masters and all his friends are at the burger joint and Masters has just received a letter saying he has been denied enrolment into the US air force academy, his enemy Knotcher tries to humiliate him by announcing it over the loudspeaker. Masters then runs up to the window and threatens to assault him. Knotcher suggests that a race would be more appropriate to which they both agree. During this whole conversation, Knotcher's right arm is up, next shot it's down, then up, then down again.
Continuity mistake: When Doug Masters is told that his father has been shot down, he is told (roughly) that "He waxed three of the bastards". He only shot down two enemy fighters.
Continuity mistake: When Doug comes in to drop the Hades bomb you can see that the landing gear is down as if the plane is coming into land, but when the bomb is shown being dropped the gears are up.
Continuity mistake: In the scene where Doug first approaches Chappy on the tarmac about helping to get his dad back, Chappy says he doesn't know Doug's Dad, but he knows the type. Later, after Chappy has agreed to help Doug rescue his dad in the restaurant, he relates a story about meeting Doug's dad in the simulator room at the Air Force Base and how Doug's dad took up for him during a misunderstanding with 2 other pilots.
