Amazon is looking beyond the usually issues at other threats such as hacking or "a malicious person shooting an arrow" to take down the drone.
Amazon has filed a patent for flying warehouses that could use a fleet of drones to make deliveries to customers.
"An AFC may be positioned at an altitude above a metropolitan area and be created to maintain an inventory of items that may be purchased by a user and delivered to the user by a [drone] that is deployed from the AFC".
Amazon latest adventure in the revamp supply-chain model is to introduce a flying warehouse to cater exigencies and cash on the sudden spur in demands.
The patent follows news earlier this month that Amazon had made the first successful delivery by drone, after shipping a parcel to a customer in Cambridge.
The document was filed in 2014, but was found by Zoe Leavitt from CB Insights, who tweeted yesterday: "I just unearthed the Death Star of #ecommerce via @cbinsights".
A shuttle would dock in the air to return the drones, ferry in workers, and resupply the warehouse.

Bradley vowed to "fight like crazy" in the wake of the ugly loss to the Hammers, but admitted that his future was out of his hands.
Amazon has yet to comment on the filing, but any launch would doubtlessly require a lot of regulatory approval before launching. If a drone is hit, it could deploy an airbag, foam, a parachute, a bumper, or configure one or more rotors for autorotation.
The drones would communicate with each other using a mesh network to give information regarding weather, wind speed, and route plans; they could even beam e-book content down to readers on the ground.
An example cited in the filing was around a sporting event. A special drone will be used to drop off the products ordered, making less hassle on delivery trucks or motorcycles catching up the highway traffic.
The plan is for Amazon's PrimeAir service to eventually deliver small packages weighing up to 5lbs (2.27kg) in 30 minutes or less.
The most challenging of the success of this flying warehouse model is how Amazon will cut the cost and save the energy for no payloads.
Since the drones that Amazon is testing can't get up to heights as high as 45,000 feet, the company says its used drones will fly back to a ground installation, where they'll be placed in a shuttle and brought back to the AFC.
