HILL AIR FORCE BASE, Utah -- Air Force Reserve Tech. Sgt. Jeremy Rogers, an aerial spray maintainer assigned to the 910th Aerial Spray Maintenance Flight, operates the control panel of a Modular Aerial Spray System (MASS) on the cargo deck of a C-130 Hercules cargo aircraft parked on a flight line ramp here, March 30. Sergeant Rogers and a team of 910th Airlift Wing Citizen Airmen will use the MASS to apply an herbicide mixture to more than 1200 acres of target areas on the Utah Test and Training Range (UTTR). The 910th, based at Youngstown Air Reserve Station, Ohio, home to the Department of Defense's only large-area fixed wing aerial spray unit, has been tasked, through April 7, with controlling Halogeton, an evasive weed that can hamper bombing test evaluations and unexploded ordinance recovery.
