A C-17 from March Air Reserve Base, Calif., sits on the flight line of Davis-Monthan Air Force Base after delivering an HH-60 to the 943rd Rescue Group Jan. 28, 2016. The helicopter was the Air Force Reserve Command’s first HH-60 to go through Korean Air Lines depot maintenance, which involves an intensive overhaul that removes all corrosion and brings the aircraft back to like-new condition.
