California Civil Code, 1708.8: (a) A person is liable for physical invasion of privacy when the person knowingly enters onto the land or into the airspace above the land of another person without permission or otherwise commits a trespass in order to capture any type of visual image, sound recording, or other physical impression of the plaintiff engaging in a private, personal, or familial activity and the invasion occurs in a manner that is offensive to a reasonable person. (b) A person is liable for constructive invasion of privacy when the person attempts to capture, in a manner that is offensive to a reasonable person, any type of visual image, sound recording, or other physical impression of the plaintiff engaging in a private, personal, or familial activity, through the use of any device, regardless of whether there is a physical trespass, if this image, sound recording, or other physical impression could not have been achieved without a trespass unless the device was used. It is not a defense to a violation of this section that no image, recording, or physical impression was captured or sold. Now, I have read a lot of rules and regulations regarding where you can and cannot fly a quad in California, and nowhere have I see it stated that you cannot fly a quad over someone else's property. In fact, it always was my understanding that a homeowner owns the land his house sits on, but not the airspace above it. So WTF? Does anyone have any experience with this particular (apparent) law in California or a similar law in any other state?
