For more, every time you see anyone at the podium in front of a GIANT US flag, they are in the hangar bay that I worked at. That flag was still hanging up until about 3 weeks before we closed the doors. In one scene, I believe you see the very end of the tail of aircraft 34. The number isn’t seen, but just the back edge of the rudders. Unmistakable from an F-18 (or 14)
Also, they used the VRC-30 Ready room but re-decorated as their “ready room” for the movie. I couldn’t see anything in those scenes to reflect the original decorations.
The beach bar, totally fake, doesn’t exist. Hollywood built a temporary structure for the movie and took it back down when they were done.
