Byrd warned today that the United States should adopt measures of protection against the possibility of an invasion of the country by hostile planes coming from the polar regions. The admiral explained that he was not trying to scare anyone, but the cruel reality is that in case of a new war, the United States could be attacked by planes flying over one or both poles. This statement was made as part of a recapitulation of his own polar experience, in an exclusive interview with International News Service. Talking about the recently completed expedition, Byrd said that the most important result of his observations and discoveries is the potential effect that they have in relation to the security of the United States. The fantastic speed with which the world is shrinking – recalled the admiral – is one of the most important lessons learned during his recent Antarctic exploration. I have to warn my compatriots that the time has ended when we were able to take refuge in our isolation and rely on the certainty that the distances, the oceans, and the poles were a guarantee of safety. Adherents to the Hollow Earth hypothesis believe that Admiral Byrd flew over the North Pole and into the hollow earth in February 1947, and that he kept a secret diary of the incident. This belief was first published in F. Amadeo Giannini's book The Worlds Beyond the Poles: Physical Continuity of the Universe (1959). Giannini writes that Byrd encountered a humanoid being from another "world" who warned humanity to pursue peace and not war; he also reports that Byrd spotted a living woolly mammoth near the North Pole
