First tests conducted with pilotless flying bombs

The earliest flight with an unmanned flying bomb, the Kettering Aerial Torpedo (known later as the Kettering Bug), was conducted in the USA, on 2 October 1918, during World War I. The bomb, which was designed by Charles Kettering (USA) and built by the Dayton Wright Airplane Company, was intended to have a range of 80 km (50 miles), however the Great War ended, funding was withdrawn, and therefore this early form of cruise missile was never actually used operationally.
