Autonomous delivery drone fleet taking-off with their payload in a crowded urban airspace. The drones are managed via the new National Drone Network for Commercial Delivery, Medical Transport, and Urban Air Mobility. A drone drops its package into a roof-top box, then the man who ordered the goods picks-up his package. Those sorties will be managed by one centralized, autonomous Unmanned Aircraft System Traffic Management (UTM) located in the traffic and air traffic control centers of the Ayalon Highway Company in the central Haifa Bay. The event took place during demonstration of Aerial Control Center for Drones and Joint Flight of Different Drones in a Single Managed Airspace in Hadera, Israel.
