Though this may be a marketing thing, the Nazi UFO connection is about as old as the Nazi/Vril connection and the Nazi/Hollow Earth connection. I get the impression that it probably came out of the (well known) connection between prominent Nazis and the Thule Society (though it's unclear whether or not they were True Believers -- they had an obvious interest in the use of propaganda, and any cult that can convince a large number of people that they live on the inside surface of the earth with the sun in the center has something to teach you about propaganda) and the use of ex-Nazis in the cold war space-race (via Paperclip). I'm not sure if there are any reliable sources indicating flying-saucer wunderwaffen, but it's a pretty short leap. In fact, the idea of Nazi UFOs may predate the end of WWII, given the prevalence of foo fighters (including saucer/cigar types -- not just ghost rockets) during the fighting. I remember reading something about I want to say swedes or finns blaming the foo fighters on the Germans (the US and UK soldiers generally assumed they were Japanese weapons, as implied by the term 'foo fighter', though there is evidence that the term predates world war two and simply owes some of its popularity to this assumption).
