I made a little search on net and it seems that this whole UFO thing is connected to nazi Germans and antarctica.
Could they be preparing an invasion or are they american vessels?
Terziski maintains that antigravity research began in Germany in the 1920s
with the first hybrid antigravity circular craft, the RFZ-1, constructed by the
secret Vrill society. In 1942-43 a series of antigravity machines culminated
in the giant 350-foot-long, cigar-shaped Andromeda space station, which
was constructed in old zeppelin hangers near Berlin by E4, the research
and development arm of the SS.
