I think one person can fly several drones.
I really terrified of drones. Thise that fire missiles - it was recognised as a new step in the barbarity of warfare when aerial bombardment became a thing around WW2. I was scared to go outdoors as a young girl, because I'd seen aeroplanes dropping bombs on TV. We had q a lot of fighter jets nearby.
I can't imagine how the children of Gaza, Ukraine have been scarred by a manmade, mechanized bird that can home in on them, chase them & kill them, just appearing at random from the skies. I really hope for some new legislation on them, they give me the creeps.
