Sighting of UFO on military base.

This is not recent but happened when I was in the military stationed at NAS Fallon, Nevada in the sixties.
As Navy personel we were required to pull all kinds of watches and one of the guys in the squadron was assigned to patrol the aircraft parked on the flightline.
While patrolling a saucer shaped craft came overhead. It had a white light that shined straight down and made no noise at all that he remembered. This frightened him quite a bit and he went in the hanger where the watch supervisor was at his desk and asked him to come and see the craft.
When they went back outside it was gone but the fellow who saw it was so excited that he wanted to call the Air Force early warning radar site which was also on the base at that time.
The radar site said, "Yes we saw something on radar but we get blips like that all the time." This tells me the Air Force was very aware of what it was. Also none of us knew of groom lake at the time which was only a short jet flight from Fallon.
I always wondered where they got it if it was Air Force.
This was all duly entered into the VA-125 night watch log.
The witness took a lot of flack over the sighting and the next day in the log someone wrote. 2100 no saucers sighted.
However the man who sighted was not the kind of person that made things up or sought attention by doing things like that.
Obviously I'm not a witness. I only was stationed there with the guy at the time.
