Airmen keep B-1B ready for bombs on target
Staff Sgt. Trevor Helm washes the windshield of a B-1B Lancer prior to a mission Jan. 29 at an air base in Southwest Asia. The windows require a special solvent to clean them due to the material used in its creation. Sergeant Helm is a crew chief for the 7th Aircraft Maintenance Unit deployed from Dyess Air Force Base, Texas. He is a native of Lisbon, Maine. (U.S. Air Force photo/Staff Sgt. Joshua Garcia)
