Grebennikov) (1927-2001) was a Russian scientist, naturalist and entomologist who claimed to have invented a levitation platform which operated by virtue of insect body parts attached to the underside. Grebennikov wrote detailed accounts of his 1988 discovery, which involved an accident whilst examining chitin shells. He also wrote of his experiencies flying over the Russian countryside in his book titled "My world". The Cavernous Structure Effect (CSE) he discovered is an alleged anti-gravity effect.
