Dean,
On one of the hollow-earth sites, there is a whole series of German, W.W.II
stories about the Nazi's quest for the hollow earth. I know for a fact, from
a friend who served during W.W.II, that the Nazi's had built air strips in
Greenland. They used the hot water, from hot water springs, piped in
underneath the runways, to keep them from freezing. This old timer told me
this years ago, because he was so impressed with their ingenuity, and I was
too, that's why I never forgot his mentioning this to me over 30-years ago.
