Dynalifter "Drone Runner"

The Dynalifter Drone Runner is an airborne mothership for package delivery drones.  Dynalifter are ideal because they fly slow enough to deploy and retrieve slow-moving package drones.  Also, unlike other airship concepts, the Dynalifter is the one design rugged enough to operate daily.  Non-rigid airships, or blimps can only operate in near-perfect conditions.
