In this episode of UFO Hunters, they go looking for Nazi Saucer technology wich ultimately leads them to German Scientists and NASA and they also compare the Kecksburg, P.A. UFO with the Nazi "Bell"
Die Glocke - Wikipedia, the free encyclopediaDie Glocke (German for "The Bell") is the name of a purported top secret and highly sensitive Nazi scientific technological device. The only source of this theory are the books of Polish aerospace defence journalist and military historian Igor Witkowski, which claim it to be a secret weapon, or Wunderwaffe. The topic has been popularized by Nick Cook, Joseph P. Farrell and conspiracy theory websites, associating it with Nazi occultism and antigravity or free energy research.
