I, nor any crew I was on (I was on three Apollo crews), received any briefing before or after flights on UFO events, saw anything in space suggesting UFOs or structures on the moon, etc. We did it just like we said in official reports. My only claim to knowledge of these events is from the individuals, mostly of yesteryear, who were in government, intelligence, or military; were there, saw what they saw, and now believe it should be made public. But I claim no first hand knowledge, nor have any. Pass it on to the rest of the net, if you will.
