Drones are aircraft or unmanned flying machines originally designed for military operations. These devices safeguard pilots who operate the drone remotely. The drones for civilian use began to appear in 2012 as the outcome of developments made by universities, and soon after was made available to the public. The number of manufacturers who have marketed these devices have sold it really cheap and became popular. Today you can buy a drone online for prices starting from 35 US$ and up.
Studies on the proliferation of drones said it will be double the number of users per year, as they are highly popular and widely used for sports, for recordings of private and commercial video and other personal uses.

An explosive device can be easily attached to a drone or terrorists might use it to simply mark targets making these devices a very dangerous weapon.
