Three U.S. Army Air Corps officers in tropical pith helmets pose beside a liaison/observation aircraft, likely a Stinson Vigilant, on a bare desert airstrip. The star-and-disc insignia with its red center dot, discontinued in May 1942, dates this image to the final years before America's entry into World War II, when Army aviators served at scattered overseas outposts in tropical and arid climates.
