Nutrition in industry. New stainless steel rolling cafeterias are hauled by tractor-train down one of the half-mile-long aisles of Boeing's Kansas plants, each filled with sufficient food to feed 250 hungry aircraftsmen. At stations spaced 250 feet apart the wagons will be uncoupled and attendants will set up shop on the feeding line. Because of the convenient locations selected, no employee will have to walk more than a few steps to get his wholesome mid-shift meal. Sourced from the Library of Congress.
