Amazon Patents Flying Warehouse for Better Drone Deliveries
Amazon.com/U.S. Patent and Trademark OfficeAmazon.com has to use airships to store products and serve as a base for delivery-drones.

According to the patent filing, drones launched from the so-called "airborne fulfillment centers," or AFCs, would use far less power than those launched from the ground.
The AFCs would hover at about 45,000 feet and be restocked and resupplied by "shuttles or smaller airships."
Amazon, which was not immediately available for comment, has laid out plans to start using drones for deliveries next year.
