In this technological age in which we live, it is important to look to the future for things to come. In this vein, I look to the sky. It is my understanding no air craft can legally fly less than 500 feet from the ground. I now look at the sky above my own property. I feel the length and width of my property times the 500 feet above my property is the cubic feet of my own space, and anyone or thing in it without my permission is trespassing.
I believe this could be legally defended.
