Nikola Tesla's next idea team, led by one of his students, Otis Carr, designed a functional prototype of a flying saucer. Evidence of this is given by one of the team members - Ralph Ring in the document: The man who flew with flying machines.

The machine has a certain resemblance to the artistic rendering of the Indian Vimanas, in ancient Vedic texts. In the same way, we can find an analogy in the petroglyph of the Hopi tribe.
