U.S. Air Force Tech. Sgt. Darren Ricchiazzi, crew chief for the 379th Expeditionary Aircraft Maintenance Squadron, marshalls out a KC-135 Stratotanker at Al Udeid Air Base, Qatar, Nov. 18, 2020. The aircraft launched immediately after hot refuel training during which maintenance crews safely refueled the aircraft while the engines remained running. This capability allows the KC-135 to rapidly redeploy and carry on the mission of continuous aerial refueling across the globe. (U.S. Air National Guard photo by Staff Sgt. Jordan Martin)
