United States Government Role in Civil Aviation - Airmail

Airmail

With initial help from the U.S. Army, the Post Office in 1918 initiated an intercity airmail route. The subsequent achievements of the Air Mail Service included the establishment of a transcontinental route and the development of airway lighting.

In 1925, the Airmail Act of 1925 authorized the Post Office to contract with private airlines to transport mail. The Airmail Act created American commercial aviation and several of today's airlines were formed to carry airmail in the late 1920s (including Trans World Airlines, Northwest Airlines, and United Airlines).
