Night-time view of the Miss Pittsburgh and Miss Youngwood (right background) mail planes at Bettis Field, Allegheny County. The pilots are Dewey Noyes & Merle Moltrup.
In 1922 Representative M. Clyde Kelly of McKeesport submitted his first airmail bill to the House of Representatives. President Calvin Coolidge signed the Kelly Air Mail Act into law on January 17, 1925. The act had a clause that provided for the government to foster commercial aviation. Government encouragement would have an enduring effect on the aviation industry.
