U.S. Air Force civil engineers from Yokota, Japan, and U.S. Navy Seabees from San Diego, Calif., gather Sept. 22, 2010, for their last tribute to the islanders of Yap, Federated States of Micronesia, as they perform group push-ups during Pacific Unity 2010. Pacific Unity 2010 is a humanitarian civil engineering effort in which civil engineers completely rebuilt, remodeled and repainted a high school on a remote island in Micronesia.
