U.S. Air Force Staff Sgt. Jayme Ross, back, 100th Logistics Readiness Squadron Allied Trades NCO in charge from Hartford, Conn., oversees U.S. Air Force Staff Sgt. Matthew Mason, 100th LRS Vehicle and Equipment Maintenance craftsman from Eatonton, Ga., adding a fuel additive which eliminates the production of excessive exhaust fumes and pollutants into the air on one of the flight’s recently acquired buses Feb. 6, 2015, on RAF Mildenhall, England. This additive is important because it ensures the flight’s ability to minimize their environmental impacts in the United Kingdom while sustaining an effective military presence in the European Theater in support of the sole aerial refueling and special operations mission.
