Thunderbirds in flight
The U.S. Air Force Air Demonstration Squadron "Thunderbirds" fly the Delta formation July 6, 2011, during the Koksijde International Air Show in Belgium. A Reserve C-17 aircrew from the 326th Airlift Squadron hauled the Thunderbird team and their equipment making it possible for them to participate in this air show and another that same week in England.
