The relatively low-cost of smart commercial drones make them work for civilian applications.   Drone aircraft are sophisticated and flexible.   They take off, fly and land autonomously managed by a remote controller.  They enable engineers to push the envelope of normal flight.   Reconnaissance drones can fly for days continuously.   Remote, ground-based pilots can work in shifts.  

Video, specialized video, targeted video, and package delivery systems are offered.   Smart commercial drones have a computer inside.  They are easy to fly, maneuverable remotely, contain sensor logic.  Soon all smart drones will have computer driven collision avoidance technology.   Remote operation occurs in the context of a workflow and sensors.  Cameras are improving dramatically to permit management of video and picture taking that is realistic and detailed.
