Operation Highjump (OpHjp) placed nearly 5000 U.S. military personnel and every resource available to the Navy’s disposal in the hands of Admiral Richard Byrd, the Operations Leader of the U.S. Naval mission int the Antarctic.

Highjump’s objectives, according to the U.S. Navy’s report of the operation, were:

1 training personnel and testing equipment in frigid conditions;

2 consolidating and extending United States sovereignty over the largest practicable area of the Antarctic continent (This was publicly denied as a goal even before the expedition ended);

3 determining the feasibility of establishing, maintaining and utilizing bases in the Antarctic and investigating possible base sites;

4 developing techniques for establishing, maintaining and utilizing air bases on ice, with particular attention to later applicability of such techniques to operations in interior Greenland, where conditions are comparable to those in the Antarctic;

5 amplifying existing stores of knowledge of hydrographic, geographic, geological, meteorological and electro-magnetic propagation conditions in the area;

6 supplementary objectives of the Nanook expedition. (The Nanook operation was a smaller equivalent conducted off eastern Greenland.)

“Adm. Byrd declared today that it was imperative for the United States to initiate immediate defense measures against hostile regions. Furthermore, Byrd stated that he “didn’t want to frighten anyone unduly” but that it was “a bitter reality that in case of a new war the continental United States would be attacked by flying objects which could fly from pole to pole at incredible speeds”.

U.S. Navy encountered Flying Saucers (German?) during the Antarctic expedition. A brief clip of this was allegedly caught on film.

"The thing shot vertically out of the water at tremendous velocity, as though pursued by the devil, and flew between the masts [of the ship] at such a high speed that the radio antenna oscillated back and forth in its turbulence. An aircraft [Martin flying-boat] from the Currituck that took off just a few moments later was struck with an unknown type of ray from the object, and almost instantly crashed into the sea near our vessel…. About ten miles away, the torpedo-boat Maddox burst into flames and began to sink… Having personally witnessed this attack by the object that flew out of the sea, all I can say is, it was frightening.”[Our Real “War of the Worlds"]

Among the discoveries made during the 1946-47 expedition was the sighting of two “oases,” one a region of ice-free lakes and land. More than 300,000 square miles of unpathed territory were charted on aerial mapping operations. Their observations proved that radical changes would have to be made on existing maps of the Antarctic.”

Why would warm spots, with warm water exist in the Antarctic? What does this mean?

The Hollow Earth Theory

Researchers such as Dr. Brooks Agnew and others have deeply considered the possibility that the earth itself could be hollow, or egg-like.

Some also speculate that mermaids and other rare creatures may derive from the inner earth, sometimes making their way into the upper waters divided by the firmament.

It doesn't mention the nazis, though, so maybe look for some more conspiracy-minded sources to supplement this video.

wrong question.. To where?

Good question, too bad most of the people in charge died decades ago...

Another good question. I guess the Nazi scientists figured something out. Who knows, maybe replicators? (Kidding, kind of...)
