Airman 1st Class Rachel Rodgers, a fuels expediter assigned to fuels distribution with the 2nd Logistics Readiness Squadron acts as a safety person as she holds a hose down toward the bottom of a fuel tank at the test cell on Barksdale Air Force Base, La., March 27, 2012. Her position on the tank is imperative for safety reasons. Pressure from the pump could force the hose from the man hole soaking anyone in the area with fuel. From her advantage on the top of the tank she can ensure fuel flow from the barrels and tell pump the operator to shut-down the pump if the fuel level is about to reach capacity. Rodgers was part of a multi-unit group of Active Duty and Reserve Airmen as well as civilian engineers who were preparing to test a new fuel mixture in a TF34 jet engine, which is military turbofan engine used on the A-10 Thunderbolt II.
