In 1935, the British produced several radio-controlled aircraft for use as training objectives. It is believed that the term “drone” began to be used around this time, inspired by the name of one of these models, the DH. The first time the use of an unmanned aerial system was in 1849, when hot air balloons loaded with explosives began to be used in the war. The prevailing winds swept the balloons to the target area, where they fell and released the payload.
This English word comes from the Germanic train (drone), from the word drunjus. Drunjus was used in the Gothic period (noise) and from the Greek “threnos” (funeral song). The word drone was first used to refer to an unmanned aerial vehicle in 1946, but advances in drone technology in recent years have made the term much more common. There is no doubt that a word used for a quarter of a century will gain some more definitions and, in the early 1960s, the definition of “drone” went from being an aerial target used by British forces in World War II to a word that could be retroactively applied to the German V-1, an air target used by British forces in World War II.
