In the 21st Century, the word ‘Drone’ is often associated with war, death and fear.
So, what exactly is a drone? A drone, also known as a UAV (unmanned aerial vehicle), is an aircraft controlled by pilots from the ground (often utilizing a mobile app).
There are numerous types of drones; basically they fall into two categories: those that are used for surveillance purposes and those that are armed with missiles and bombs.
We need to focus on the surveillance aspect, instead of those drones being used in the theater of war.
