Have you ever visited an airport? It is often a very exciting place. If you are near an airport, why not go inside? You do not have to be a passenger to go inside it. Sometimes you may have to pay to enter an airport but is always a small amount.
An airport is usually full of people. Some of them will be passengers. Some have just arrived by plane and they are now waiting for transport to take them home. Others are waiting to go on planes that will take them to another city or another country. They are buying something or talking to their friends. Above the airport the planes may be circling in the air. They are waiting their turn to land. There must be someone to control all these places. If you look around the airport you will see the control tower where the men who control the planes work. If they make a mistake people may be killed.
