Senior Airman Shakielia Dennis-Lightner, 52nd Logistics Readiness Squadron fuels distribution operator, prepares the fuel trucks to “hot pit” fuel F-16 Fighting Falcons during a Flying Training Deployment at Monte Real Air Base, Portugal, Feb. 13, 2019. Hot Pit refueling means an aircraft is refueled on the ground while the jet engine is still running, allowing the aircraft to quickly return to the skies for another mission.
