Amazon files patent for flying warehouse equipped with drones

Amazon has filed for a patent on a flying warehouse equipped with drones to deliver goods. The warehouse would be carried by an airship and would visit places where Amazon expects there to be high levels of demand. The patent also covers support vehicles designed to restock the structure, which would hover 45,000ft (14,000m) in the air. Documents show Amazon believes the combination of the flying warehouse and drones would deliver goods considerably faster than ground-based warehouses, the BBC reported. There are suggestions the warehouses would be located above festivals or sporting events and smaller airships could act as shuttles taking drones, people and supplies to the warehouse.
