The air traffic control tower on Maxwell Air Force Base, Alabama, is made up of seven flights of stairs leading to the observation room where air traffic controllers have a 360 degree view to monitor Maxwell Air Force Base’s flight line. Air traffic controllers monitor Maxwell’s flight line to ensure the safety of ground maintenance crews and aircraft crews by directing aircraft on and off the flight line safely.
