Amazon's 'Mothership': Retailer Gets Patent for Mega-Drone

What happens when you connect a flock of flying drones? You get a "collective unmanned aerial vehicle" that's capable of lifting heavier burdens and flying greater distances than smaller drones can, according to a patent recently granted to online retailer Amazon. The Amazon Technologies Inc. patent describes a large and robust flying drone made up of numerous smaller drones, designed to make long-distance flights or to carry heavy packages.
