An airport is a place where planes fly in and out. Planes fly to different cities, countries, continents, and even different parts of the world. The airport is a very busy place. Inside of the airport there are different buildings, like a terminal, runways, and control towers. The terminal is where you check in and out of your flight. The runway is where the planes take off and land. The control tower is like a big building that is responsible for managing the flow of the air traffic coming in and out of the airport. People who work in the control tower help the airplanes navigate safely in and out of the airport. There are also many different types of stores and restaurants inside of an airport.
