Drones, otherwise known as "unmanned aerial vehicles" (UAV) or "unmanned aerial systems" (UAS), are aerial devices flown remotely by pilots on the ground. These devices are being used for a variety of purposes, from the well-known military drone strikes overseas, to photography around the world, to common recreational use. Law enforcement agencies are begning to use drones, as well, to conduct surveillance on suspected criminals. This guide will seek to provide information on common uses of drones, including legalities and functionality.
