I stepped out for a few after this and when I came back in JR told me he had seen the lights too, in a different spot just hovering. We heard more jet engines in a distance and also saw several airplanes at low altitude fly over here making absolutely no sound. We saw the orange lights fade in and out in the sky for about 30 minutes, but they seemed to move further away. At one point I saw 3 lights simultaneously.
This is very unusual activity for this quiet neighborhood.
