Other mistake: Why do the good guys keep shooting 2.75in unguided rockets to kill the enemy aircraft? These are designed to kill lightly armored vehicles and trucks on the ground. You would have about as much luck with those as with chucking rocks at planes. There are infared (heat-seeking) Stinger missiles on the wing pylons, we see Billie pull one off and attach the hand held unit to shoot down a jet. Why aren't they using those?
Factual error: The crashed Apache has dirt piled around it as if it hit nose first and slid to a stop. Yet the chopper crashing at over 100 mph didn't even scratch the glass FLIR sensor on the nose. Obviously, dirt was just shoveled around a stationary Apache or a mockup.
Visible crew/equipment: In the middle of the mortar attack on the staging ground, if you look carefully at the AH-64 Apache in the rear you can see what looks like a reflection of the sun, however the sun is not rectangular, so it must be a floodlight.
