I haven't heard that saying for quite some time now, but a few years ago, there were a few people who began claiming that we never even went to the Moon, but rather our government faked the whole thing to freak out the Russians with our superior technology.
I'm not going to repeat the claims of the "Moon Landing Hoaxers" or the hoax debunkers here, you can do a quick search and see what they're saying, but a friend sent me a link to this creative video where a photographic expert explores the issue from a unique perspective. His basic premise is, we probably had the technology to go to the moon in 1969, but we certainly didn't have the technology to fake it.
Anyway, it's worth a watch. I certainly enjoyed it.
