An aircraft traffic counter is one of the tools the 1st Operations Support Squadron air traffic control tower staff uses to support flying missions to and from Langley Air Force Base, Va., and the local area. The counter helps air traffic controllers keep track of flights arriving and departing as well as transitioning through Langley AFB’s airspace. The tracked flights are then reported to Air Combat Command headquarters to keep track of the unit’s logistics. (U.S. Air Force photo by Staff Sgt. Natasha Stannard/Released)
