Factual error: Gene Hackman is the Adriatic Fleet Admiral. While onboard the aircraft carrier, he carries out duties as the captain of the carrier. The only people who can give orders on a carrier are the ship's captain or the airwing captain. Gene Hackman could only give orders to the captain, who in turn would give orders to the crew.
Factual error: During the Recon flight launch, one shot shows the Super Hornet taking off with a blue Sidewinder. These blue missiles are simulation Sidewinders, and as stated in the Top Gun mistakes (same missiles used), all they do when launched is drop from the aircraft. (00:14:50)
