Nazi Moon Base
Apparently, the Fuehrer didn't limit his land-grabs to the Earth. A popular conspiracy theory posits that Hitler had Nazi scientists reverse-engineer UFOs using alien technology. Then, when the war was coming to an end, Hitler was sent to the moon, presumably for safe-keeping. "Using rocket technology, the Nazis sent Hitler to a secret base on the moon," The Sun reports. The 2012 movie Iron Sky depicts the Nazi's returning from this moon base to establish a Fourth Reich.
