During his tenure as Congressman, Clyde introduced a resolution to permit private contracting of airmail service. This resolution, the Air Mail Act of 1925 was signed into law on February 2, 1925, prompting many companies to venture into the aviation field (e.g., Boeing, Douglas, and Pratt & Whitney). The Airmail Act of 1925 was the foundation that commercial aviation is built upon.[1]
After his time in Congress, he resumed his former business pursuits. He was accidentally shot while cleaning a rifle and died in a hospital at Punxsutawney, Pennsylvania. Clyde was interred in Mahoning Union Cemetery, near Marchand, Pennsylvania.
