Visible crew/equipment: When Brubaker hides out in the Petrol station, the two helicopter pilots approach the window. A reflection of a member of the crew wearing glasses can be seen reflecting in the window where the pilots stand.

Revealing: When the three Astronauts crash the Lear jet in the desert, on the outside shots of them walking in their separate directions, there are no marks behind the jet to show that it skidded across the surface where it stopped.

Revealing: Just after the helicopters crash during the chase with the crop duster keep a close eye and one of the helos is still in the shots flying.
