Amazon has applied for a patent that gives more insight into the infrastructure it may be planning for its drone delivery program, Amazon Prime Air. In this case, the drones would take off, land and pick up deliveries from a tower placed in densely populated cities that would house the drones. It looks a lot like a bee hive.
