The biggest airport in the world in the 1980s was the Atlanta, Georgia, airport, which was officially called the William B. Hartsfield Atlanta International Airport.
Its building covers 2.2 million square feet, enough space for seven 31-story office buildings. It has a subway, 13 newsstands, 12 gift shops, 17 snack bars, and 138 airplane gates from which planes depart and arrive.
There are over 1,200 public telephones, and the area is lit by more than 100,000 light bulbs. People can push a button with one finger and get a question answered by a translating machine in six different languages.
Instead of having to walk to departure gates, people are zipped to their destinations by mini subways that leave every two minutes. Moving without a sound, these mini subways can transport 11,200 people an hour.
