As early as 1936 Hitler was sending teams of "Spelunkers" into caves and mines all over Europe searching for the Vril-ya. The Nazi's had also explored Antarctica extensively during the years 1937-38. In search of the fabled hole of the South Pole they apparently had success, like Admiral Byrd, in discovering these entrances. It was here that some say they made contact with the "Unknown Superman" who lived in the fabled "Rainbow City". In his controversial presentation UFO Secrets of the Third Reich, Vladimir Terziski draws a connection between alien beings and such German secret societies as the Tempelhof, the Thule, the Vril, and the Black Sun. Terziski tells of an "alien tutor race" that secretly began cooperating with certain German scientists in the late 1920's in underground bases and began to introduce their concepts of philosophical, cultural, and technological progress."
