This graduation announcement and dinner-dance program commemorate Navigation Class 43-5 of the Air Force Advanced Flying School at Mather Field, California, which graduated on March 27, 1943. Mather Field was one of the U.S. Army Air Forces' principal navigator training schools during World War II, producing thousands of navigators for bomber and transport crews. The accompanying dinner dance, held the evening before graduation at the Elks Temple in Sacramento, reflects the social traditions that marked the completion of demanding aircrew training programs.
