This aircraft was originally the sole DL-2, a Sirius with a metal fuselage built in Detroit. By April 1931 it was converted to DL-2A Altair with retractable gear, and delivered to the US Army as the Y1C-23, a fast VIP transport often flown by Ira Eaker. Initially it still wore civil reg NR8494. Here it is seen wearing Bolling Field insignia and simplified designation C-23 just behind the cowling, which should date the photo between 1933 and 1935. On some photos the Secretary of War's flag is painted on the other side. Following a gear-up landing it was rebuilt and repainted in light blue in 1935. Condemned to ground instructional airframe following another belly landing with jammed gear in April 1938. Photo from: US Air Force
