IF YOU ARE MAKING BURGERS ON YOUR BACKYARD BAR-B-CUE AND YOU SEE A DRONE DROP DOWN TO SPY ON YOU, WOULD IT BE POLITE TO OFFER IT A BURGER? I JUST READ HOW DRONES CAN COME IN ALL SIZES FROM FULL SIZE SMALL PLANE TO MODEL AIRPLANE SIZE. THINK OF THE POSSIBILITIES.  YOUR SON IS PARKED ON THE LAKESHORE WITH HIS GIRL WATCHING THE SUBMARINE RACES AND YOU CAN DIRECT YOUR PERSONAL DRONE DOWN TO CHECK ON HIS SAFETY.  SPIES WHO SEEK TO DO DAMAGE TO ATOMIC POWER PLANTS OF POWER LINES CAN ALERT OFFICIALS TO THE DANGERS.  A DRONE COULD SCARE THE PIGEONS OFF BUILDINGS.  THE POSSIBILITIES ARE ENDLESS.  ISN'T SCIENCE WONDERFUL?
