I would suggest before you start shooting you should read the whole "United States vs. Causby" decision rather than a few "cherry picked" paragraphs. For instance, let me cherry pick:
In the Court’s words, landowners held title only to airspace situated within the “immediate reaches” above their land. At a minimum, those immediate reaches included airspace areas that the landowner could “occupy or use in connection with the land.” They also encompassed airspace through which unwelcome aerial invasions would “subtract from the owner’s full enjoyment of the property.” The Causby Court’s fuzzy standards left plenty of unanswered questions. Just how high above land did the “immediate reaches” extend? And what sorts of airspace uses were sufficient to satisfy the Court’s “occupy or use” standard? The Court openly refused to address these questions or to offer any further guidance regarding the upward limits of landowners’ airspace rights, declaring instead: “We need not determine at this time what those precise limits are".
sourceI think I'm pretty sure you're not going to be "occupying or using" space a hundred feet above your house.
