Senior Airman Austin Clayton, 28th Operations Support Squadron air traffic control journeyman, sketches a prevailing visibility observation graph at Ellsworth Air Force Base, , Jan. 7, 2016. Weather can affect flight conditions and visibility, which makes directing aircraft more difficult. Ellsworth’s tower covers five nautical miles, making visibility observations important to mission success. ( Air Force photo illustration by Airman 1st Class James L. Miller/Released)
