A B-1 bomber performs a ‘touch and go’ as two air traffic controllers communicate with the aircrew to ensure the take-off goes smoothly at Ellsworth Air Force Base, S.D., Jan. 6, 2016. It takes a team of air traffic controllers to coordinate all aspects of flight operations, from taking off in clear airspace to landing on the runway. Air traffic controllers coordinate approximately 25 sorties a week, keeping pilots prepared for contingency operations. (U.S. Air Force photo illustration by Airman 1st Class James L. Miller/Released)
