We could be getting them again. > On December 28 of last year, the Chinese firm EHang reached an important milestone. They flew a completely unmanned, autonomous passenger drone on its first commercial flight in Guangzhou. They were able to transport a human passenger without a pilot, using 16 different rotors and fueled entirely by an electric battery. It made for a much quieter vehicle than a typical helicopter and (in principle) a greener one, too.
