What about them? Both of those can violate air rights, and in the US both have FAA regulations that apply. I’m using the US as an example because I live in the US, but many many countries have similar regulations. Small drones need a remote pilot license, and drones large enough to carry a human require an actual aircraft pilot’s license just like any other airplane or helicopter. In a public park in the US, small drones are required to stay under 400 ft altitude above ground, inside the airspace of the park. (Small drones are also required to not fly directly above other people.) Aircraft with people in them are required to fly higher than that, which thus defines an altitude threshold above which is considered outside of land-based public and private property boundaries.

The question in the quiz about flying airplanes over a park can be correctly answered with 3 pieces of information: the aircraft type, the park’s location, and the altitude. The question cannot be answered without that information. Contrary to the author’s attempted point, the correct answer to the question is not a matter of language ambiguity.
