Hollow Earth

1964 Dr. Bernard says this is the true home of the flying saucers. The epoch-making significance of Adm. Byrd s flight for 1,700 miles into the North Polar opening leading to the hollow interior of the earth, the home of a Super Race who are the Creators of the flying saucers will startle the world. The author claims that this remarkable book proves that there exists on the inside of the earth s crust, which is about 800 miles thick, a New World, and that Admiral Byrds polar expeditions penetrated a total distance of 4,000 miles into this Land Beyond the North and South Poles, where there exist immense openings leading to the subterranean world in the hollow interior of the earth, home of a super race and super civilization.
