The first attempt at a trained UAV was A.M. Lows „Aerial Target“ in 1916.  Low confirmed that Geoffrey de Havilland was the only one flying under control with his radio system on March 21, 1917.  Nikola Tesla described 1915 a fleet of unmanned air combat vehicles.  Progress followed during and after the First World War, including the British Hewitt-Sperry Automatic Airplane (1917) and the RAE Larynx (1927). These developments also inspired the construction of Charles Kettering`s Kettering Bug in Dayton, Ohio. Originally designed as an unmanned aircraft, which would carry an explosive payload to a predetermined target. The first scale remote control vehicle was developed in 1935 by movie star and model enthusiast Reginald Denny.  During the Second World War, there were others, both to train aviation advocates and to fly attack missions. Nazi Germany produced and used several drone planes during the war, such as the Argus As 292 and the V-1 flying bomb with a jet engine. After World War II, development continued in vehicles such as the American JB-4 (using the TV/radio control), the Australian GAF Jindivik and teledyne Ryan Firebee I of 1951, while companies such as Beechcraft proposed their 1001 model for the U.S. Navy in 1955.
 Yet, until the Vietnam War, they were little more than remote-controlled aircraft. In April 2014, South Africa`s civil aviation authority announced that it would tackle the illegal theft of drones in South African airspace.  „Amateur drones“ weighing less than 7 kg at altitudes below 500 m with reduced visibility below the height of the highest obstacle within 300 m of the UAV are permitted. No license is required for these vehicles.  So far, the endurance of small aircraft is the best thing to do with flapping wing vehicles, followed by aircraft and multi-roters coming in last place due to the small number of Reynolds.  A UAV is defined as „a powered aircraft that does not carry a human operator, provides aerodynamic forces, provides elevators, can fly autonomously or can be flown remotely, can be consumable or recoverable, and can withstand a lethal or non-lethal payload.“  Therefore, missiles are not considered drones because the vehicle itself is a weapon that is not reused, even though it is unmanned and, in some cases, remotely controlled. In addition, UAV is a term often used in cases of military use.  The term unmanned aircraft system (UAS) was adopted in 2005 by the U.S. Department of Defense (DoD) and the U.S. Federal Aviation Administration, in accordance with its 2005-2030 roadmap.  The International Civil Aviation Organization (ICAO) and the United Kingdom Civil Aviation Authority have adopted the term, which is also used in the European Union`s Air Traffic Management Roadmap (ATM) Research (SESAR Joint Undertaking) for 2020.  This term emphasizes the meaning of elements other than the aircraft.
It includes items such as ground control stations, data connections and other support devices.
