If you have ever flown a drone in your life or been close to one that flies, you know the noise that the propellers make. And I'm talking about a small drone. Can you imagine having 1000 of these huge drones flying over your head all day? This is one more thing to entertain us in things that will never be reality ... at least with the technology that currently exists. And I'm just talking about the noise not to mention other things that are worse.
