The glider works using a new anti-gravity pillow technology. The principle is the same as that of the ekranoplans of the 20th century, having an air flow between the wing and the surface that holds the structure. The glider has the same thing but with antigravity field of a small order (instead of air stream) holding the structure 2-4 meters up the surface, regardless roughness and uplands of the planet. Traction is created by the standard reliable ramjet engine. ***If you like the work, you can buy 3d model and Glider video on Rarible*** https://rarible.com/rezepov
