Google has been working on self-driving cars for some years now, but the company has just revealed that it is working on yet another ambitious and autonomous vehicle project. According to the BBC and The Atlantic, the secretive Google X team has been working for two years on Project Wing, a drone-based delivery system that sounds a lot like the Amazon drones that CEO Jeff Bezos announced last year. However, while Google says these vehicles can be used for delivering goods, the project's main focus doesn't appear to be appeasing shoppers who need things right away. Instead, it sounds like Google envisions using these drones in disaster relief scenarios — they could theoretically deliver supplies to areas in need. "Even just a few of these, being able to shuttle nearly continuously could service a very large number of people in an emergency situation," said Google X's Astro Teller to the BBC.
