A white to red haze and solid looking craft came in to view over our western sky, it was not a airplane or a blimp. there was no sound of a motor, no running lights. this was not a recognizable aircraft of any type i'm aware of, including the tr-4 . i know i wouldn't get a straight answer if i called the airbase, but when these craft show up every year at this time, i start to wonder what's going on. they have been here for awhile now, my wife and i go out and look at them, usually three of them at different points of the sky, and there seems to be nobody else that's interested. these craft are gone in the morning, then show up at dark. my wife and i know enough astronomy to be sure that these are obviously not planets or space junk, (they're too low).
