Here you go: FAA Reauthorization Act of 2018, enacted and approved by the President at the time, states in part:And yet you chose to respond.
Nobody has proven to me that you can do whatever you want with your toy contrary to my rights as a private citizen.
In Class G (Uncontrolled) Airspace, an aircraft (such as a UAV) may be flown from the surface to not more than 400 feet above ground level and must comply with all airspace restrictions and prohibitions. See FAA Advisory Circular 91-57B at § 7.1.6 (May 31, 2019), https://www.faa.gov/documentLibrary/media/Advisory_Circular/AC_91-57B.pdf. UAVs cannot fly in controlled airspace without an FAA authorization. Id. at § 7.1.5.2.
Class G is unregulated airspace, such as that found above most people's private property. Regulated airspace A, B, C, D and E is generally at or around airports or other no-fly areas. As to your "Constitutional Right to Privacy", to date, the courts have ruled against it, in the case of drones, unless one can prove it was used for an unlawful purpose, such as taking lewd photos.
But it gets more complicated than that. The Federal government lays claim to regulating the skies - from above the surface of your land to outer space. Some states have set regulations both allowing and prohibiting drone flight over private land, but to date, none that I am aware of have been taken to the SCOTUS to be accepted or denied.
