Idk if anyone had a similar problem before, but I live in EU by the countryside, at first there were only a few but now it happens more and more often to see drones passing over my house, I am sure they are civilian drones because law enforcement has no reason to use them since the area is quiet (and honestly I doubt they would be able to do so), however it bothers me enough to know that there are people who get over the fence and enter my property going to look at what they want, does anyone have any advice on what to do?
you own the airspace up to the highest point of your property
Nope. Part 103 pilots often fly inches off the ground and it’s totally legal- usually farm fields. This is called class G airspace and extends from surface to 700 or 1200 ft AGL. The United States government has exclusive sovereignty of airspace in the US from the surface up, and any citizen has the right of transit through that airspace.
