American Antigravity. Er..I’m konfused, are these ‘lifters’ for real or is this some elaborate…ah…charade?

‘Lifters are prototype field-effect propulsion devices powered by high-voltage supplies. They’re made of aluminum and other lightweight materials…Lifter technology is currently being investigated to determine if the anomalous side-effects noticed in testing are in fact gravitational in nature, but Lifter technology is probably not “true” Antigravity.’
