During the Apollo mission I worked at NASA throughout those Apollo missions and I did leave NASA at the time the space shuttles began. I worked in building eight in the photo lab. I had a secret clearance so I thought I could go anywhere in the building. And I did go into one area that was a restricted area. In this area they developed pictures taken from satellites and also all of the missions, the Apollo missions, flight missions. I went in and I was talking to one of the photographers and developers and he was putting together a mosaic which is a lot of photos, smaller photos into a larger photo pattern. And while I was in there I was trying to learn new methods and new things about the whole organization and I was looking at the pictures and he directed my attention to one area, he said, Look at that. I looked and there was a round oval shaped, well it was a very white circular shape of a dot and I, it was black & white photography, so I asked him if that was a spot on the emulsion and he said, "Well I can't tell you, but spots on the emulsion do not leave round circles of shadows."
I thought about another incident with a guard that I would like to convey too that's very important. This man that I had dated was in quarantine with the astronauts when they had come back from the moon and I had talked to him about seeing this saucer (satellite photos) and asked him if he had heard anything about that and he told me that every astronaut, every moon trip had been followed by craft, by saucers, that every one of them, every astronaut that went to the moon, now I don't know about other sites but they all had seen it and all had been told to keep quite about it and they were threatened with jail and their whole retirement, everything taken away from them. They were also, this told me that if I ever told that he said it, that he would deny it, that he would never admit that he told me all of that.
