Viktor Stepanovich Grebennikov — naturalist and a professional entomologist. He is also an artist and an intellectual with a wide range of interests and pursuits. He is known to many as the discoverer of the Cavity Structures Effect (CSE). But very few people are familiar with his other discovery, the one that also borrows from Nature and its innermost secrets. He has discovered anti-gravitational effects of the chitin shell of certain insects back in 1988 but, the most impressive concomitant phenomenon he has discovered at the same time was that of complete or partial invisibility and/or of distorted perception of material objects entering the zone of compensated gravity. Based on this discovery, Victor Grebennikov used bionic principles to design and build an anti-gravitational platform for hovering flights at the speeds of up to 25 km/min. Since 1991-92 he has allegedly used this device for his own fast transportation.
