GTA UFO Location.
Here is the crashed GTA UFO Location. It is pretty deep down and the pressure will kill you. Use a scuba set, the Toreador or the Kraken to get there.
The position of the UFO GTA is here, almost as north as you can get.
I landed the helicopter beach bove, ran into the water and started swimming north close to the bottom until I found the UFO.
