The Newark area of the TRACON covers Newark Liberty International Airport along with the majority of the TRACON's satellite airports including Teterboro Airport, Morristown Municipal Airport, and Caldwell/Essex County Airport.
Nick "The Zone" Falzone (John Cusack) and his fellow air traffic controllers at New York TRACON pride themselves on their ability to handle the intense stress of being a controller for one of the busiest airspaces in the country, even boasting of the 50% drop-out rate for new additions to the staff who are unable to cope with the pressure.
