Pilotless drones, also called UAVs(or Unmanned Aerial Vehicles), have evolved to become some of the most cost effective tools in the modern world, they are very successful and much safer and more militarily effective than their ancestors and their piloted counterparts.
As the 21st century advances, so does the need for a safe and cost-effective method to transport and fight with the least amount of money and resources spent. The answer: pilotless drones. These safe and effective machines are the new generation of aerial and space flight. Drones have been flying since the Civil War, but they have never been too famous with the public. Before the first manned flight, there was primitive UAV technology in use. There was the Perley's Aerial Bomber in 1863, this primitive form of UAV was merely a hot air balloon with a timing mechanism. there was also the Eddy's Surveillance Kite which was a large kite that took photographs from the air, in fact, these photos were the first successful aerial photographs.
