Master Sgt. Rob Donnelly conducts pre-flight checks on an EQ-4 Global Hawk before it's first launch Nov. 27, 2010, from an undisclosed location in Southwest Asia. The EQ-4 carries the Battlefield Airborne Communications Node (BACN) which acts as a persistent gateway, bridging diverse tactical data links and voice communications to improve battlefield communications. Donnelly is from the 380th Aircraft Maintenance Squadron. (U.S. Air Force Photo/Staff Sgt. Eric Harris)
