Manpower. Former actress now aircraft worker. From central casting to aircraft casting! Erstwhile child star of the silent picture days, auburn-haired Dorothy Langdon now inspects airplane engine parts in a Detroit war plant. Known as "Baby Dorothy Phelps" of the silents, and heart interest of western thrillers in the middle thirties, Miss Langdon joined America's army of women war workers early this year. With a husband in the Army, the twenty-six-year-old beauty finds her new role in life eminently satisfying. "I'm really doing something," she says. "I got tired of just playing at doing something." In addition to her forty-eight hour work week at the inspection table, Miss Langdon still finds time to study drafting at night
