Ok, I've got one:
The Saturn V was built in Siberia with the help of the Russian mob, the Inuit's and the Yeti (on loan from the Himalayas). It was then transported to a secret Nazi base in Antarctica via a subterranean ocean by the Illuminati (Walt Disney himself supervised this, as well as provided significant funds to the project). At the same time, a second Saturn V was built (at Area 51, by the church of Scientology), to be launched from Vandenberg specifically to throw conspiracy theorists off the trail.
Meanwhile, back at the Jimmy Hoffa Space Center in Antarctica, The real Saturn V was assembled by the teamsters union (overseen by the greys, of course). The crew were CDR.William Rutledge (whom, as stated before was a Teamster and a Freemason), Nazi Mission Specialist Leona Snyder, and Alexi Leonov's Illuminati clone.
