From the history of drones
In the beginning, drones were almost exclusively the province of militaries. At first little more than remote-controlled model planes used in the World War I era, military drones advanced steadily over the decades, eventually becoming sophisticated tools that could surveil battlefield enemies from the sky. Today, the terms “drone” and “unmanned aircraft system” denote a vehicle that navigates through the air from point A to point B and is either remotely controlled or flies autonomously. While they vary in size and shape, such vehicles all feature a communications link, intelligent software, sensors or cameras, a power source, and a method of mobility (usually propellers).
Until recently, that is. In the last several years, a new group of actors has come to embrace drones: private companies. Inspired by the technological progress made in the military and in the massive hobby market, these newcomers have realized that in everything from farming to bridge inspection, drones offer a dramatic improvement over business as usual. The potential for the commercial use of drones is nearly limitless.
