Bill Hanks, a Yahoo contributor, asks questions about Nazi Bell technology in brief article, "Nazi Bell; Science Fiction or Secret Weapon?" Hanks wonders about the disappearance of SS General Hans Kammler, the man responsible for the Bell project and its vast documentation? One rumor has both loaded on a cargo plane to the United States or South America?
Hanks provides a nice summary of the physical principles. "The Bell device consisted of two counter rotating cylindrical containers. The containers were positioned one above the other. They were filled with both cryogenically cooled and frozen Mercury metal. There was a frozen core of a metallic paste, which served as a high permeability material for an electromagnetic gravitational field also called vortex compression."
After the war, Hanks points out similarities between the Nazi Bell UFOs and George Adamski's classic films and the the 1965 Kecksburg, PA sighting. Also, Betty and Barney Hill related, while under hypnosis, the aliens they encountered looked like Nazis in uniform! Hanks concludes by calling the disappearance of Hans Kammler and the Bell technology, "one of the unknown mystery's of our time"!
