Factual error: The F-16 in the movie is wearing a desert camouflage, this is the standard camouflage of the Israel's air force F-16 while the USAF F-16 have two tonalities of grey
Factual error: All of the 'MiGs' flown by the Soviets are actually McDonnell Douglas F-4 Phantoms. Obviously, it would have been very difficult to use real MiGs at that time. However, why they chose to use one of the most well-known, long-serving, widely-used, and distinctive American aircraft is beyond me. The F-4 does not even slightly resemble any Soviet aircraft, while many other American (and other countries') planes do.
