The weapons developed by the black operations science divisions of the Nazi party
led to many 'radical' aircraft experimentations, including the 'One Wing' Horton planes
of 142-foot wingspan submitted for approval in 1944, which would have been able to fly
from Berlin to NYC and back without refueling, thanks to the blended 'one wing' design
and six BMW 003A or eight Junker Jumo 004B turbojets.
Also, the first rocket airplanes and jet airplanes as the Messerschmitt Me 163 Komet
and Messerschmitt Me 262 were fully developed and functional.
However, German UFO theories describe successful attempts to develop advanced
aircraft and spacecraft prior to and during World War II, and further assert the post-war
survival of these craft were carried on in secret to underground bases in Antarctica.
Allegedly, the first model was called JFM "Jenseitsflugmaschine" or "Other World
Machine", that was followed by the RFZ "RunFlugZeug" or the "Round Aircraft" series
that finally derived in the Vril and Haunebau projects.
