Holy urine dump, Batman, wouldn't anything ejected tend to travel in formation?
I'm glad someone else remembers John Glenn's "constelation Urine."
Virtually every sighted human being who has looked up at the sky has seen something up there that they weren't able to identify. By definition those are all "unidentified flying objects."
Buzz Aldrin doesn't say he saw a flying saucer. He says they saw something close enough to observe which they couldn't identify, ergo it's a UFO. I'll bet the way he phrases the "we didn't tell anybody" comment makes it clear that he knew it was nothing, but that fruitcakes would claim it was an alien and try to force them to come back.
I've met and spoken briefly with Aldrin. He's one of the most clear headed engineers I've ever run across. No nonsense at all. That's why I was so offended by the way he was portrayed in From The Earth To The Moon. Tom Hanks couldn't resist at least one attack on a great person for simply daring to express his belief in God and Jesus Christ.
