It was flying in circles in the western sky and continued in a very similar flight path for the 45 minutes that I was observing it. As this is the first time in my 54 years that I have experienced such an event I moved location to get an unrestricted view. It was flying above the slight low cloud that was in the sky, but it was quite clear to see at most positions in it's flight path. I had the impression that it was flying at quite a height above the ground notwithstanding that I observed it at only a short distance above the horizon and I felt that it was some distance away from me. There was no sound coming from the direction of this moving light in the sky, but the amazing thing was that soon after my sighting I heard aircraft flying from the direction of the Benson Air Force base in the direction of this moving light in the sky. Could it have been possible that they detected something and scrambled aircraft to investigate ? ... Wow what an experience !!! ...
