I’m a dork for liking flying and airports as much as I do. It’s not based on any modern reality, just nostalgia for what it used to be like. And one of things I used to love at airports was, while waiting for a flight, going to the observation deck and watching the planes.
There are several pieces, designed to help visitors understand airport operations and what is going on. Especially interesting are the “medial telescopes” (or “Airport Scopes”) through which visitors look to get details about any of buildings or airplanes that are in view.
