The U.S. Air Force Thunderbirds participate in the Warriors Over Wasatch Air Show at Hill Air Force Base, Utah, June 29, 2014. The open house not only included the Thunderbirds but also featured three aerial performers: the U.S. Army Golden Knights, a F-16 demonstration, an Air Force Heritage Flight, which displays the evolution of the U.S. Air Force air power, and 13 premier civilian acrobatic demonstrations.
