The final episode covers the period 1955-present. Throughout the last century, covert surveillance has been key to military success. Over the trenches, the eye in the sky had been indispensable. But as defenses against airplanes improved through the decades, the airplanes themselves have undergone a transformation of design. New technology has allowed them to become, for all intents and purposes, invisible, and their advanced avionics have made them ever more agile and self-reliant. At a time when the human pilot is becoming the limiting factor in the capabilities of an aircraft, many believe we are entering a new age of autonomous, pilot-less warplanes that will once again transform combat as we know it.
