With this mod we can access and go to some hidden interiors of the universe in GTA San Andreas. You will now have access to hidden locations such as the Shamal and Andromeda plane cabin, the Los Santos Stadion interior, a slice of Liberty City, or even interiors that were never used in the final version of the game. This mod I paired with some useful mods like Flying Camera, airbreak, and sky run might help you get there easily.
