Fort Zancudo

The second is over that hippie camp that also has the glyphs.

And the third spawns in over the Fort Zancudo airfield.

In total, three unidentified flying objects became temporarily visible after 100% completion.

And you can only imagine, and we can only imagine how excited the person who found these things first must have been.

What's very interesting though, is that the UFOs which appeared over Chiliad and the hippie base, had an FIB logo on them.

The FIB, or Federal Investigative Bureau, is the GTA version of the real FBI, so these two saucers belong not to extraterrestrials, but the United States government.

Whatever was flying above Fort Zancudo, however, appears to be genuinely extraterrestrial and uses a different model that has no human markings.

What in Talos's name is going on here? Why would the FIB be flying these things around? Well, it's very possible this is just futuristic FIB tech.
