The world's first UFO-type manned electric vertical take-off and landing aircraft took its maiden flight in Shenzhen, the tech powerhouse in south China's Guangdong Province. Featuring a six-hole conduit with 12 propellers, the aircraft can take off and land on water, making it amphibious. It was in development for more than three years and was primarily designed for sightseeing tourism and advertising performances. | China Focus
