Shot of cars driving on a tree lined highway. A Greyhound bus pulls into a bus depot. Shot of a train pulling into a station. A well dressed woman walks to a cabin and settles in with the aid of a porter. Shot of the train speeding down the tracks. Shot of a luxury liner cruise ship at sea. On board, a radio operator mans a large radio console covered in switches and knobs. Close up of the controls as the man adjusts them. Shot of a switchboard operator at work. A woman relaxing at home on a couch answers her telephone. The radio operator starts a stopwatch. Shots of a jet liner airplane flying through the clouds.
