Drones are used in military exercises to fly reconnaissance missions or deliver ordnance. They may fly a pre-programmed course with limited “decision making” ability of their own or be remotely controlled.
Hobbyists have been flying radio controlled airplanes and helicopters for decades. Due to improved designed and new lightweight materials, today’s aircraft look very different from what your father or grandfather might have flown back in the 70’s or 80’s. But unless you belong to a paramilitary organization (militia or a terrorist cell) then you do not have a drone. We have adopted that word into our lexicon from military use and hear it on the news every day used incorrectly.
I know it’s too late. Just like ATM Machine and PIN Number the word drone is part of the American vernacular and people are going to keep saying it. I just want to say once for the record: Those people are wrong.
