               1. A three-vehicle control system for navigating a primary aerial vehicle in a jet stream, the control system comprising: 
            a primary wind speed sensor on the primary vehicle for measuring jet stream wind speed; 
                a port side wind speed sensor on a port side aerial vehicle for measuring jet stream wind speed on one side of the primary sensor; 
                a starboard side wind speed sensor on a starboard side aerial vehicle for measuring jet stream wind speed on the other side of the primary sensor; 
                a calculation module in communication with the primary wind speed sensor, the port side wind speed sensor, and that starboard side wind speed sensor for determining a maximum wind speed vector from the respective primary wind speed sensor, port side wind speed sensor, and the starboard side wind speed sensor, wherein the maximum wind speed vector has a direction and magnitude toward a location of a maximum wind speed of the jet stream; and 
                a lateral movement controller configured to control lateral movement of the primary aerial vehicle and move the primary aerial vehicle with respect to the direction and magnitude of the maximum wind speed vector.
