SPANGDAHLEM AIR BASE, Germany – Senior Airman Stephen Denney, 52nd Aircraft Maintenance Squadron, marshals an F-16 Fighting Falcon pilot into position for hot-pit refueling here Feb. 16. Hot-pit refueling saves time, manpower and equipment usage by using a Type-4 hydrant system to refuel active aircraft between training missions. Refueling still-running aircraft requires fewer Airmen and no refueling trucks because only two 52nd Logistics Readiness Squadron Fuels Distribution Airmen are needed to operate the hydrant system.
