Dear Mr. Linn,
Thank you for posting your request on History Hub!
According to the U.S. Army Veterans Medals website, Air Medals are “awarded to any person who, while serving in any capacity in or with the armed forces of the United States, shall have distinguished himself by meritorious achievement while participating in aerial flight. Awards may be made to recognize single acts of merit or heroism or for meritorious service.” You may wish to contact them directly to see if they can offer you any additional assistance.
The Military Times website offers additional information about Air Medal Recipients, and the Roll of Honor website offers this information about the Air Medal, too. The blog post Air Medal: Eligibility and History may also be of interest to you.
We hope this information is helpful, and best of luck with your research!
