Airspace

Airspace is the portion of the atmosphere controlled by a country above its territory, including its territorial waters or, more generally, any specific three-dimensional portion of the atmosphere. It is not the same as aerospace, which is the general term for Earth's atmosphere and the outer space in its vicinity.

Airspace may be further subdivided into a variety of areas and zones, including those where there are either restrictions on flying activities or complete prohibition of flying activities.

Horizontal boundary

By international law, the notion of a country's sovereign airspace corresponds with the maritime definition of territorial waters as being 12 nautical miles (22.2 km) out from a nation's coastline. Airspace not within any country's territorial limit is considered international, analogous to the "high seas" in maritime law. However, a country may, by international agreement, assume responsibility for controlling parts of international airspace, such as those over the oceans. For instance, the United States provides air traffic control services over a large part of the Pacific Ocean, even though the airspace is international.

John Paul Cusack (/ˈkjuːsæk/, born June 28, 1966) is an American actor, producer and screenwriter. Cusack appeared in several teen films in the mid-1980s, most notably Better Off Dead (1985), before he starred in Cameron Crowe's romantic comedy-drama Say Anything... in 1989.

Early life

Cusack was born to a Catholic Irish-American family in Evanston, Illinois. His mother, Ann Paula "Nancy" (née Carolan), is a former mathematics teacher and political activist. His father, Richard Cusack (1925–2003), was an actor, as are Cusack's siblings Ann, Joan, Bill and Susie. Richard was also a documentary filmmaker who owned a film production company and was a friend of activist Philip Berrigan. Cusack graduated from Evanston Township High School in 1984, where he met Jeremy Piven, and spent a year at New York University before dropping out, saying that he had "too much fire in his belly".
