What rights did the court establish in United States v. Causby (1946) regarding property ownership?

In United States v. Causby, the Supreme Court established that landowners possess rights to the airspace above their property, but these rights are not unlimited. The ruling emphasized the principle that while a landowner has some ownership of the space above their land, this ownership extends only to a reasonable height necessary for the enjoyment of the property.

The court noted that low-flying aircraft could interfere with the use and enjoyment of land, supporting the idea that property rights include not only the surface but also a limited column of airspace above it. This ruling effectively established the need to balance property rights with the realities of air travel, recognizing that while landowners have rights, they do not own the airspace indefinitely as they do the land itself.

This reasoning illustrates the concept of reasonable use, where landowners have certain rights that allow them to use their property without excessive interference, but these rights must also consider the needs and regulations of air travel. This nuanced approach provides flexibility and respects both property rights and the need for aviation operations.
