Avionics specialists with the 12th Aircraft Maintenance Unit prepare a Global Hawk unmanned aerial vehicle for a runway taxi test Oct. 13, 2006, at Beale Air Force Base, Calif. The Global Hawk is scheduled to begin flying at Beale in early November. The program is a total force effort with the Air Force Reserve Command's 13th Reconnaissance Squadron assisting active-duty personnel. The Global Hawk can survey large geographic areas with pinpoint accuracy to give military decision-makers the most current information about an enemy, its location and its resources.
