Two F-15s from the 142nd Fighter Wing, Oregon Air National Guard, fly over the Western Air Defense Sector during the F-15 static display dedication ceremony Sept. 13. The WADS has been guarding America's skies in the same building 24/7 since 1960 and regularly uses F-15 alert aircraft to perform its mission. (U.S. Air National Guard photo by Kimberly D. Burke)
