Many people over time have reported their sightings of flying saucers and many of these have reported that the disc was spinning. Some people have reported fantastic speeds at which the saucer then disappears. Wouldn't the g forces of a disc flying and spinning crush anything living and even play havoc with the navigation mechanics and electronics? Can a gyroscopic feature be created that would remain level and stable whilst the saucer spins? If yes then how would one maintain the electronics between the gyroscopic pod and the outer ring as they would have to work in harmony yet independant of each other?
Maybe it is creating artificial gravity. Or the outer case may spin and leave the inside still. Who knows ? Maybe you could ask them next time you see them, or perhaps you have a theory of your own.
Ah and apparently they won't experience fantastic G forces because their aparent movement isn't movement at all. They just take the space ahead of their vehicle and transfer it behind them, so they stay still and reality moves around them :-)
Most flying saucer sightings are a direct result of the drugs the viewers are taking. Those that aren't are just not identified. Yes you are correct spinning beyond a certain speed would be fatal as would acceleration beyong a certain rate. I would imagine, to work, gyroscopes must be self contained.
