"Amazon.com Inc has filed for a patent 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" (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."
Besides the danger to passenger jet traffic in the flight levels, the danger to all other traffic in class E airspace is concerning. Sure, they would probably make drop zones where the drones can get below 3k feet AGL, but they have to go horizontal at some point, making low level VFR highly dangerous.
Or am I too pessimistic?
