U.S. Air Force members take apart an engine on a KC-135 Stratotanker at Incirlik Air Base, Turkey, Nov. 15, 2018. Many of the KC-135’s are over 60 years old and are often in need of maintenance after each flight, which is why it is important for the deployed members of the 22nd Expeditionary Aircraft Maintenance Unit to work 24/7, ensuring the aircraft are in proper operating condition.
