Area 69
Area 69 is the highly protected and secretive government airbase in Bone County, San Andreas. The base is a spoof of the real life Area 51. In the past, the base was associated with the long held rumour of aliens and UFOs in the game. Entering the base results in a 5 star wanted level. You infiltrate the base to find the jetpack in the mission "Black Project".
Flying over the base in a plane results not only in the wanted level, but SAM missles and Hydra jets will track you down and attempt to destroy your aircraft.
