U.S. Air Force Captain Graham Stewart, a native of Dubois, Wyo., speaks to airplane enthusiasts on March 4 in Geelong, Australia, during the 2011 Australia International Airshow. Stewart is an F-22 Raptor pilot and currently assigned to the 525th Expeditionary Squadron, Elmendorf Air Force Base, Alaska. The event is one of the largest airshows in the world. The U.S. and Australian alliance spans more than 60 years and provides an opportunity for U.S and senior military officials to engage with their Australian counterparts, and ultimately contribute toward interoperability between the two forces.
