A row of B-24 Liberator heavy bombers rests on the flight line at an airfield during World War II. These four-engine bombers were mainstays of the U.S. Army Air Forces' long-range bombing campaigns in both the European and Pacific theaters. The relaxed, shirtless posture of the airman in the foreground hints at the hot climate typical of Pacific airbases, where ground crews endured intense heat while servicing and preparing aircraft for missions.
