There were a number of applications for TV guided weapons developed both by our country and the Germans. The GB-4 glide bomb is probably what is being referred to in the documentary. It was dropped from a bomber and using a TV camera and 300 mhz transmitter,it gave the remote control operator in the bomber an image to aim for with his radio controls.
War weary B17 and B24 bombers were also fitted with the camera/transmitter package and, laden with explosives, were taken airbourne by a pilot who was supposd to bail out after reaching a certain altitude and the plane sent to it's target by radio control from a chase plane some mile behind it. JFK's oldest brother was killed on such a mission when the plane he piloted blew up before he was able to bail out.
The majority of thes setups,called Block, used RCA Iconoscope cameras and RCA transmitters but Farnsworth also built cameras,too for the military.
