They will have to establish a heliport for the drones and dispatch from a central location. Imagine all the factors for a truck and crew to drive to a general location and be responsible for drone launches. Truth is the delivery of packages by drones is merely one of the technologies emerging capabilities. Warfare seems to be where the money and science is currently and primarily invested. Delivery of consumer goods is way back on that list.From what I have read is the drones will be used from a delivery truck of sorts. The truck will act like a base station so it does not have to drive everywhere to deliver packages. It will be for more rural America from what has been reported on. So basically the truck is loaded in the morning with packages going to the same general places and sets off on its way to rural America where it finds a location to send off the drone.
