In the haze of a light fog, Tech. Sgt. Salomon Gutierrez, 62nd Aircraft Maintenance Squadron noncommissioned officer in charge of silver flight, prepares to spray deicing liquid onto the wing of a C-17 Globemaster III at Joint Base Lewis-McChord, Wash., Jan. 16, 2019. Snow and ice can make the aircraft heavy and freeze the flight-control surfaces making it unsafe for takeoff. (U.S. Air Force photo by Senior Airman Tryphena Mayhugh)
