The sensational journalism and economic prosperity that marked the Jazz Age in the United States allowed barnstormers to publicize aviation and eventually contributed to bringing about regulation and control.[1] In 1925, the U.S. government began regulating aviation, when it passed the Contract Air Mail Act, which allowed the U.S. Post Office to hire private airlines to deliver mail with payments made based on the weight of the mail. The following year, President Calvin Coolidge signed the Air Commerce Act, which shifted the management of air routes to a new branch in the Department of Commerce, which was also responsible for “licensing of planes and pilots, establishing safety regulations, and general promotion.”[7][8]
