At first glance, it appears to be a video game, but it is not. Each number on the screen represents an aircraft, and the lives of the passengers are dependent on your prompt, decisive, and consistent command. The federal government employs and trains the majority of air traffic controllers. Although the compensation and perks are outstanding, the stress level is significant. 

You must speak clearly, work in a team, and be constantly on the alert if you work at an airport control tower to ensure planes stay a safe distance apart on the ground while taking off and landing; a terminal area control facility' or an en-route control centre monitoring travel through invisible highways in the sky. 

The goal is safety, but air traffic controllers also seek to minimise delays. Each controller is part of a countrywide system that generates an elaborate airborne ballet, adjusting to weather, technical issues, and all the minor details that frequently pose major problems for pre-planned flight plans. 

People interested in working in this demanding field must pass a federal civil service exam and be tested on their capacity to cope with mental stress over long periods of time. A history as a pilot, navigator, or military controller improves your chances of acceptance into the federal aviation administration academy, which trains air traffic controllers.
