UPS has enhanced drone efforts this week, by delivering a package by drone in Tampa, Florida. This non-commercial dry run is unique because it has hosted by a mothership delivery vehicle which provides a recharging station for the delivery drone unit. This process demonstrates microscopic efficiency, as once the drone is launched, the vehicle can continue on it's way while the drone is moving a package.
Critics will often mention friction saying "I don't have a yard" and "that's insecure to theft". This answer is simply. Aerial collection and distribution hubs will exist. Image a fenced in UPS receiving zone with drone facilitating employees and other ground delivery people taking packages to their final destination. These distribution centers are already being planned as aerial fortress versions, floating about our cities, by Amazon CEO & Founder, Jeff Bezos.
