The UFOs are, in my opinion, the evolution of Graviton Engine vehicles that the NatSocs developed in the 1940s. We got most of their good physicists and chemists as a part of Operation Paperclip. And yes, these theories were very similar to/identical to the theories of Tesla. "If you want to understand the universe you must think in terms of frequency and vibration."
