Women aircraft workers assemble wing flaps for U.S. Superfortresses. American women workers at a plane plant in the Midwestern United States assemble wing flaps for U.S. B-29 Superfortresses, new-type bombers which carry a heavier load of explosive faster, farther and higher than any Allied warplane in existence. The flaps, largest ever used on any American warplane to be put into mass production, are solid structures that are extended from the trailing edges of the wings during take-offs and landings. On June 15, 1944, a task force of Superfortresses took off from newly completed bases in China and bombed Japan's Imperial Steel Works on the enemy island of Kyushu. B-29's, which can fly more than one-fifth of the way around the world without refueling, are now being produced in six of the largest American aircraft plants while hundreds of subcontractors are making plane parts. The U.S. War Department states that the program for the production of Superfortresses involves virtually every manufacturing center in the United States.
