No their isn't any

Area 69 is a fictional location from the video game "Grand Theft Auto: San Andreas." It is designed to resemble a secret military base, similar to the real-life Area 51, which is known for conspiracy theories related to UFOs and extraterrestrial life. While Area 51 is a real U.S. Air Force base in Nevada, Area 69 does not exist in reality.
Items like UFOs, and characters like Bigfoot, Leatherface, Jason Vorhees, aliens, etc. etc., do not appear in GTA San Andreas ordinary gameplay. They are myths. To produce anything like this would require a mod, available with the use of a computer. Best idea is to surf the net for availability of the mod you require, and also look at GTA dedicated websites like gtawiki and their modifications sections, to get further information.
no u can sometimes see shooting stars
As there are normally no UFOs in GTA San Andreas, you would probably need a mod for this. Try this site:www.moddb.com/mods/gta.../how-to-install-mods-in-gtasa
Some people say that there is a mod available for a UFO in San Andreas, but none appear during normal gameplay. You can see aliens in glass jars inside of the Restricted Area, though.
R* says officialy: There arent UFOs in this game.This is a lie or a mod or a glitch(Aliens doesnt exist in this game too). A UFO mod you can download everywhere
you cant find bigfoot on the xbox its only for the PC and its a mod. and if you want bigfoot i suggest you buy the PC version and go on www.filefront.com and search san Andreas and there are a hole lot of things like bigfoot,ufos,costumes { spiderman }.
Where humans and alcohol are, UFOs will be.
