(Telecompaper) Google has built and tested autonomous aerial vehicles, which it believes could be used for delivering goods. The project is being developed at Google X, the company's unit for its most ambitious research, which also came up with its self-driving car and Google Glass. The drone project, known as Project Wing, has been running for two years, the BBC reports. Google said that its long-term goal was to develop drones that could be used for disaster relief by delivering aid to isolated areas. They could be used after earthquakes, floods, or extreme weather events, to take small items such as medicines or batteries to people in areas that conventional vehicles cannot reach, Astro Teller, Captain of Moonshots - Google X's name for big-thinking projects, told the BBC. Eventually Google said it could use unmanned flying vehicles to deliver shopping items to consumers at home. The prototype vehicles that the company has built have successfully been tested by delivering packages to remote farms in Queensland, Australia from neighbouring properties.
