Factual error: Several times in the movie, you can see the airbase control centre communicate with aircraft using a VRC-46 radio. This radio, which transmits in the VHF frequency range, is not capable of communicating with combat aircraft due to the Doppler effect resulting from their high speed. Jet aircraft would use a UHF radio to communicate.
Factual error: Throughout the movie, we see soldiers at the air base control center communicate with the aircrafts using an RT-524 radio transmitter. This radio operates in the VHF range, which is not suitable for communication with fast jets due to the Doppler effect. To communicate with jets, you need a UHF range radio.
