Pilots of the United States Army Air Forces will be comfortably warm in temperatures as low as 60 degrees below zero when they receive new flying suits heated by electricity, which are being made by General-Efectric Company at Bridie amount of heat s may be adjusted tomeet changes in temperature. Many pounds lighter than the sheepskin-lined garments now used, the new suits give far more flexibility for manipulating controls and guns. They are heavy woolen union suits with wires sewed in parallel waves to stretch as freely as the wool in conforming with movements of the body. The suits have a lining of 100-percent cotton cloth which permits radiation of heat to the body, while the outer woolen fabric reduces heat loss. For the feet an electrified boot is worn.
