I was in a van on the base after working on C-130 aircraft that night. I remember it was very cold and were in the van smoking cigarettes and waiting to get the word that we were off duty (nomore aircraft to work on) well all of a sudden looking out of the van toward the apron of the runway we all saw what appeared to be a gigantic flying saucer just hovering above the runway about 20 or 25 feet above the ground, we were approximately 100 yards away from that particular spot. the thing just hovered there and glowed very bright. then all of a sudden it just raised up and shot off to the eastern horizon of the dark clear sky and disappeared. that was it. We actually did tell our maintenance control about it. they just laughed and blew it off, plus we were pretty cold and tired so we went home . I never heard any thing else about it.
