Continuity mistake: In the scene after the second crash, when the pilot and his wife "borrow" the jeep to return to the base, the shot is flipped, reversing the positions of the husband and wife in a mirror image of the real vehicle, placing the "driver" in the passenger position and the spare tire, which should be on the near side, is now on the far side. In the next shot, as the vehicle nears the base, everything suddenly resumes the correct perspective.
Revealing mistake: Janie is frozen in place on her tricycle, but the 5-year-old actress has a hard time holding still. She's visibly fidgeting. And when a freeze-frame of her is used for close-ups, there's a black blotch on the film over her neck. (00:26:30)
