Property rights do extend to the airspace immediately above the land. For example, hovering a helicopter ten feet above somebody else's house would still constitute trespass. If the GP was complaining about a buzzing drone, this test would also be relevant:
An entry above the surface of the earth, in the air space in the possession of another, by a person who is traveling in an aircraft, is privileged if the flight is conducted... at such a height as not to interfere unreasonably with the possessor’s enjoyment of the surface of the earth and the air space above it
from here. Of course, this is specifically about occupied aircraft.
There are plenty of established cases in the linked article dealing with trespass in the air above the property of others. There is also established case law regarding destruction of non-human trespassers. There's nothing specific to drones, but it's not exactly alien terrain.
