I am sure that the Earth radius has increased, and the only way it can do that is if it is hollow. I know a lot of people do not agree the radius has increased, but to me it is as easy to see as that the Earth is a globe. I'm then exploring the possibility that the Birkeland currents that enter planets at the poles enter through polar holes.
To me, I see polar holes as a valid scientific theory. The Birkeland currents (strong evidence in polar "hot spots" and overall consensus that they exist) would enter planets through the polar holes, and form a plasmoid, an energetically dense ball of plasma. These plasmoids can be produced in the lab as well, and have toroidal magnetic fields. A plasmoid inside the Earth at the center of the shell would be ideal to explain radial increase as well as shell structure, and the Earth magnetic field.
It is known and documented that on March 4th 1947, upon returning from Operation Highjump in Antarctica, Admiral Richard E. Byrd stated in an interview that was published in El Mercurio, "El almirante Richard E. Byrd advertin hoy que es preciso que les Estados Unidos adopten medidas de protección contra la posibilidad de una invasión del país por aviones hostiles proc dentes de las regiones polares. "
The National Security Act took effect later that year on September 18 1947, creating the Department of Defense with James Forrestal as the first Secretary of Defense.
That same Department of Defense recently released this video of a flying saucer,
James Forrestal was assassinated in 1949, here is the Kennedy Museum documenting when John F Kennedy visited his grave in 1963.
