A number of business are endeavoring to create Unmanned Arial Systems to deliver packages.  While we're not opposed to new opportunities afforded by advanced in technology, these opportunities must not impinge on the individuals safety, security, comfort, privacy, or property. 

The sound of Drones, their physical presence agitating livestock, domestic pets and residents as well as the danger of having them fall from the sky over private property are in direct conflict with ad coelum doctrine which, from common law, states that a property owner owns not only the plot of land but also the space above the plot.  

In United States v. Causby

The court held the public's right of flight does not extend downward to the earth's surface. finding "if the landowner is to have full enjoyment of the land, he must have exclusive control of the immediate reaches of the enveloping atmosphere. Otherwise, buildings could not be erected, trees could not be planted, and even fences could not be run" …“The fact that he does not occupy [space] in a physical sense -- by the erection of buildings and the like -- is not material. As we have said, the flight of airplanes, which skim the surface but do not touch it, is as much an appropriation of the use of the land as a more conventional entry upon it.

Commercial Drones or UAS must not be allowed to operate over private property or residential areas.  To do so is a violation of property owners property, security, comfort, privacy, and safety.
