Creating Arctic Cold in an Aeronautical Laboratory. You are looking into a room where the man-made temperature is down to 35 degrees below zero... the "all weather" laboratory of the Sperry Gyroscope Co. in which Arctic cold, tropic heat, rain or fog are created artificially. Two engineers in fur-lined flying suits are making a special test of aviation equipment. At the left is an anti-aircraft detector, which automatically trains a gun on an approaching airplane. Existence of such a laboratory illustrates, according to the Aviation News Committee of the Aeronautical Camber of Commerce, the brilliant research being carried on by the American aviation industry for national defense.
