Testing airplanes lenses used in map making. Washington, D.C., May 6. Dr. F.E. Washer of the U.S. Bureau of Standards testing the lens for the airplane cameras that are used by the Army and Navy. There are lights in the rear of the columnmeters and exposures are made on the photographic plate in front of the doctor. The lens are tested for distortion, focal length, and definition. This work must be very exacting as a small error would make an error of many miles on the maps made by the aerial cameras, 5/6/1937

Blind landing now possible. Washington D.C. It is now possible to make blind landings which has been one of the biggest difficulties to aviation. It is this single instrument located above the panel in the center directs him to the ground in a curved track and also in a straight line so as to hit the runway that is chosen for the landing. By watching the above instrument the pilot can direct his plane to the ground and determine whether he is to the right or left or above or below the beam that is transmitted. In tests that have been made the pilot has been able to land repeatedly within a few yards of the same spot
