https://en.wikipedia.org/wiki/Foo_fighter>The first sightings occurred in November 1944, when pilots flying over Germany by night reported seeing fast-moving round glowing objects following their aircraft. The objects were variously described as fiery, and glowing red, white, or orange. Some pilots described them as resembling Christmas tree lights and reported that they seemed to toy with the aircraft, making wild turns before simply vanishing. Pilots and aircrew reported that the objects flew formation with their aircraft and behaved as if under intelligent control, but never displayed hostile behavior. However, they could not be outmaneuvered or shot downSo shortly before the end of WW2 there are suddenly a lot of UFOs. There are also numerous of german blueprints around allegedly showing how the UFOs are build, and these structures resemble a lot of what people commonly refer to as flying saucer. a few years after the war we got Rosswell.
Probably easier to explain visitors from another world than a Nazi in SS uniform flying a highly advanced aircraft never seen before years after the nazi got defeated and destroyed.
The Nazis researched a lot of flying saucers/Reichsflugscheiben, like the Haunebu, the Vril or the Andromeda Gerät (Andromeda machine) which has the cigar form often common in UFO sightings, and according to the plans (will post one later) acts like a mothership harboring multiple of the flying saucer types.

Haunebu II promises considerable improvements in allmost all respects.
