I hate how everyone is quick to make crackpot theories about intentionally misleading pictures.
It's just realistic that they don't have a jetpack in the game. Like I said, there's no vertical take off assets, in GTA SA they made the Hydra, as well as the jetpack, and gave them both to us in missions.
