Members of Civil Aeronautics Authority inspect latest aid to airplane pilots. Washington, D.C., Oct. 10. An instrument which gives airplane pilots their height above the ground over which the plane is flying was demonstrated today to members of the Civil Aeronautics Authority by officials of the Western Electric Co. and the United Airlines. Claimed to be the first successful altimeter showing terrain clearance, the new device operates by radio, using the shortest wave ever employed for aviation, officials of the companies stated. In the photograph, left to right: Col. Sumter Smith, Peter C. Sandrette, Supt. of the United Airline's communication laboratory who was in charge of the demonstration; and Thomas Hardin. Smith and Hardin are members of the Civil Aeronautics Authority, 10/10/38
