In 1935, the British produced several radio-controlled aircraft for use as targets for training purposes. 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. This English word comes from the Germanic train (drone), from the word drunjus. Drunjus was used in the Gothic era (noise) and from the Greek “threnos” (funeral song).
The first recorded 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 carried the balloons to the target area, where they fell and released the payload. From Old English, the term “drone” refers to a male honey bee whose sole function is to mate with the queen. Because drones, unlike worker bees, don't have to worry about collecting nectar or pollen, they have often been seen as loafers and, in the 16th century, drones could also refer to lazy humans.
Around the same time, humming began to branch out as a verb, meaning to buzz like a bee or to speak in a monotonous way that is reminiscent of the persistent humming of a bee.
