In 1940, the anti gravity suit was first invented under the name Franks Flying Suit by Wilbur R. Franks and his colleagues at the Banting and Best Medical Research Institute at the University of Toronto. The suit was made with rubber and water-filled pads. It counteracted the effects of high G forces on aircraft pilots, which otherwise would cause them to black out; Franks Flying Suit was the first G-suit. These suits were used during World War II and all G-Suits worn by airforce pilots as well as astronauts and cosmonauts around the world are based on his original designs.
