Bill Kaysing is a former employee of the aerospace industry. There is not even universal agreement whether he quit or was fired. He wrote "We Never Went to the Moon." His final conclusion is pretty clear from the title. He maintains that the existence of various problems on the Saturn V/Apollo work site are proof that NASA didn't have the right stuff to get to the moon. (Welcome to the real world, Bill.) At the same time that he maintains that NASA was too inept to put a man on the moon, he argues forcefully that they have maintained a 100% security lock on the Hollywood production they put on to fool us all.
Rene wrote "NASA Mooned America." He similarly argues that we were too incompetent to go to the moon. His evidence consists largely of his extensive analysis of the photos released by NASA. He claims to have found a fundamental fault in nearly every photo taken. Like Kaysing, with whom he seems to have formed a mutual admiration society, he believes NASA is guilty of stealing billions in tax money, hiding the fraud with a Hollywood-like production, and maintaining silence with threats (including, of course, a number of murders).
William L. Brian, II has written a heavily referenced tome titled "Moongate: Suppressed Findings of the US Space Program The NASA-Military Coverup." His extensive bibliography includes the National Enquirer. Based on his calculations (photo analyses, times spent in transit between earth and the moon, etc.) he has determined that the moon has nearly the same gravitational force as the earth, it has a breathable atmosphere nearly as dense as earth's, both the earth and moon are not only hollow but there is an enormous opening at the earth's North Pole through which we have sailed into its interior, a terrible war was fought on the moon, and people have been living on the moon's far side for quite some time.
Finally, we have Richard Hoagland. Mercifully, he has written no book (that the Fib Finder is aware of). On the other hand, he has established a presence on the Web with his "Project Enterprise". He argues that we went to the moon--no doubt about it. In fact, nothing about the program happened by accident. The exact times and places we landed were absolutely critical. All the delays, all the scrubbed launches, all the problems were planned to the last detail so that we could be on the moon in the exact proper spot when the alignment of stars in the sky was whatever they were. The entire space program existed to worship an ancient Egyptian god and it all has everything to due with the Pyramids, Atlantis, Orion, and a colony on Mars called Sedonia.
All four use similar tactics in advancing their cases. They pose hundreds of questions, all of a speculative nature. These questions they consider proof of their arguments. It would take days to answer all the questions, even though most would be easily dispatched with a bit of common sense. On the other hand, it would be uncommon nonsense to invest your time in such an activity. The Fib Finder is certainly not going to fall into that trap. That doesn't mean we can't enter the spirit of the adventure by asking a few questions of our own.
