American soldiers in training at the Balloon School of the Signal Corps in Fort S111, Oklahoma, can be seen in the image engaged in their studies. Even during their spare time, they remain focused on their work, as shown by their creation of miniature balloons. The photograph, taken by Lt. Jackson, was censored and released by the Censor on June 21, 1918.
