Look, up in the sky! It’s a bird, it’s a plane … it’s a warehouse? That’s the dream for Amazon, which has been awarded a patent for airborne fulfillment centers. AFCs would be floating depots resembling blimps, staffed by an army of drones that would pick up merchandise and deliver it to people’s homes from 45,000 feet. It’s not clear if these now-patented sky mall dreams will ever come to pass, but Amazon, which recently completed its first drone delivery in the U.K., certainly has eyes on the sky.
