It is difficult to become an air traffic controller. All applicants must be under 31 years old, pass a physical examination, and be a United States citizen. Also, applicants must apply to an open advertisement for air traffic control positions. Next, cross your fingers. (Oh— you’ll need fingers.) People are selected randomly. Then you must pass a pre-employment test that takes roughly eight hours to complete. (Don't worry—they'll let you pee at some point—and if not, that's what Snapple bottles are for.) Upon completion, applicants train at the FAA academy in Oklahoma City for 12 weeks. After the completion of the program, candidates are assigned an air traffic control facility where they will train for two to four years to become certified.
