An automated control system for a glider towed by a tug employs a sensor system (e.g., cameras mounted on at least one of the aircraft) to determine the relative position and velocity of the glider. A controller determines corrections to the flight characteristics of the glider in response to this data from the sensor system to maintain the glider on the surface of a limit sphere extending behind the tug with a predetermined radius based on the length of the tow cable. An interface to the flight controls of the glider maintains the desired flight characteristics of the glider provided by the controller.
