Tech. Sgt. Sean Stromer, 87th Communication Squadron ground radar craftsman, rotates the digital air surveillance radar dish to ensure it can spin freely without any kinks Oct. 30, 2012, at Joint Base McGuire-Dix-Lakehurst, N.J. The dish normally spins 24/7, however, during extreme weather conditions, it is shut down. (U.S. Air Force photo/Airman 1st Class Ryan Throneberry)
