In 1947, Admiral Richard E. Byrd led 4,000 military troops from the U.S., Britain and Australia in an invasion of Antarctica called “Operation Highjump”, and at least one follow-up expedition.
Operation “High Jump”, which was, basically an invasion of the Antarctic, consisted of three Naval battle groups, which departed Norfolk, VA, on 2 December 1946. They were led by Admiral Richard E. Byrd’s command ship, the ice-breaker “Northwind,” and consisted of the catapult ship “Pine Island,” the destroyer “Brownsen,” the aircraft-carrier “Phillipines Sea,” the U.S. submarine “Sennet,” two support vessels “Yankee” and “Merrick,” and two tankers “Canisted” and “Capacan,” the destroyer “Henderson” and a floatplane ship “Currituck.”
A British-Norwegian force and a Russian force, and some Australian and Canadian forces were also involved.
Operation Highjump has become a topic among UFO conspiracy theorists, who claim it was a covert US military operation to conquer alleged secret underground Nazi facilities in Antarctica and capture the German Vril flying discs, or Thule mercury-powered spaceship prototypes. This has always been denied by the US Military
But new declassified pictures from Operation Highjump show some very odd details that do not fit in with the official story.
Just before the end of World War II two German provision U-boats, U-530 and U-977, were launched from a port on the Baltic Sea following a steady stream of supplies that was carried out throughout the closing stages of the war. Reportedly they took with them members of the antigravity-disc research and development teams carrying Notes, Drawings And Designs For German Flying Discs. The last of the most vital disc components were on these vessels.
Much of the technology and hardware that the Allies were looking for concerning the Nazi’s Secret Weapons programme had been transported to the base during the course of the war. This included the notes and drawings for the latest saucer or aerial disc designs and designs for the gigantic underground complexes and living accommodations based on the remarkable underground factories of Nordhausen in the Harz Mountains. The two U-boats duly reached the new land of Neu-Schwabenland in Antarctica, where they unloaded everything. They then arrived in Argentina several months later, minus the original cargo and most of the crew.
Rumors began to circulate that even though Germany had been defeated, a selection of military personnel and scientists had fled the fatherland as Allied troops swept across mainland Europe and established themselves at a base on Antarctica from where they continued to develop advanced aircraft based on extraterrestrial technologies.

And the logistical impossibilitys of such a thing are overruled by using levitation to get the thousands of people necessary to build huge bases? Slave labor built those in Germany and the numbers required are enormous. Far too large to transport via submarine and not practical for large ships which would be easily detected and sunk by the Allies.
