In the video Amazon Prime Air released for the concept, there's no pilot in sight. At a warehouse, a human loads the package into a special container, where a conveyor belt takes it to a drone, which then flies up from a landing pad over the factory through a field and to a distant house. In order to accomplish drone deliveries, Amazon either needs to launch the drones from delivery trucks, or it needs the drones to fly autonomously and beyond the line-of-sight of pilots. For the latter (and likelier) scenario, neither component is allowed by the FAA. As Jason Koebler notes at Motherboard, "it'll prevent Amazon from actually delivering packages over any kind of appreciable distance."
