Flirtey, the startup that did the first FAA-sanctioned drone delivery in a rural area, has replicated the feat in an urban setting. It sent out an autonomous hexacopter on a half-a-mile flight to an empty house in Hawthorne, Nevada on March 10th, carrying food, water and a first-aid kit in a box attached to a rope. It's probably not the most secure way to transport fragile objects, though, so Amazon might have to devise another method to deliver TVs or anything breakable. The drone flew with zero human intervention -- there was a pilot on standby in case things go awry, but the team programmed its flight path beforehand.
