"In
United States v. Causby, the case that decided how property rights in airspace would work, the court found that the property rights in the air over a small farm extended up to 365 feet aboveground, and therefore that government airplanes flying at 83 feet aboveground (and frightening the farmer’s chickens to death) were trespassing.
Today, your property right in a piece of land extends as high above it as “normal use of the land” requires. That is, your property right extends as high as you build, plus a reasonable buffer so that overflights are high enough to not disturb your use of the land. In rural areas, that buffer is 360 feet; in urban and suburban areas, it’s 500 feet."
