The star pattern reminded me of something i remembered, the hexagram is the shape of the insignia of the US 6th army, which for a long time trained
contential forces, especially out west.
US 6th Army
Maybe the base was once a 6th army installation years ago, when it was actively training. As sort of a unit esprit de corps thing. If it isn't,
however, its a pretty weird design to plop in the middle of nowhere.

But since you say it definitely sounded like a jet, and was coming from the sky, then it sounds like a pretty weird, unusual jet. maybe secret flight
testing of some new toy?
