Logistics Airmen ensure fuel quality
U.S. Air Force Senior Airman Kendra Jenkins, a fuels apprentice with the 379th Expeditionary Logistics Readiness Squadron Fuels Laboratory, checks fuel for additives used to prevent the fuel from freezing at Al Udeid Air Base, Qatar, Feb. 14, 2017. At high altitudes, fuel is susceptible to freezing due to the low temperatures and traces of water that may be inside the fuel. (U.S. Air Force photo by Senior Airman Miles Wilson)
