Perhaps, being the self-absorbed psuedo-genius you present, you will differentiate for me gravitational mass from inertial mass. Then you could educate us on why there is interia (no, not 'bodies in motion tend to stay in motion').
UFOs as described defy our concepts of inertia. A human technology piloted craft from 1947 stopping on a dime from 2000 mph would crush a typical pilot by G forces, but the occupants of the UFOs being observed do not seem effected by such G forces. And yes, there are credible witness sightings of beings inside the objects which have made astonishing flight maneuvers.
Prior to 'avrocar' can you cite a single wingless piloted human aircraft? Of course you can't, yet you continue to play disinformationa nd misdirection games.
. You assume I am not aware of the technology coming from WWII era...
***It is not an assumption, it is an observation. Have you read the book? What did you think? Prove that you’ve read it. Post some excerpts.
What a simpleton you’re proving yourself to be.
***Well, Betty Boop called you a psychotic and it appears from your posting behavior that she’s right. So have fun in your sandbox.
