Continuity mistake: During the catapult launch for the SAM suppression mission, we can see two Shrike missiles on the right wing pylons. In the next shot, there is only one. At this point they still haven't reached the SAM site so they wouldn't need to fire one. A little later in another shot (right before they switch to active radar) we see two Shrikes again.
Factual error: The movie states that it's set 7 years after the US became involved in the war. This would make it about 1968. When Brad Johnson and the girl are dancing, the song "Rockin Pneumonia and the Boogie Woogie Flu" by Johnny Rivers was playing, which was not released until 1972.
