In order to conduct the flying training, the school built an airfield along with buildings and other support structures.

A large aircraft parking ramp and two hangars were also constructed, along with a control tower and operations building.

The school structures consisted of a group of one- and two-story wooden buildings surrounding an oval-shaped grass area at the northern end of the property, which served as a parade ground.

The flight school also operated several auxiliary airfields: At the end of 1944, training of Free French pilots was transferred from Hargrove Van de Graaft Airport, Tuscaloosa, Alabama to Hawthorne.

During the Second World War, Hawthorne trained 5,924 military pilots, including more than 2,000 French Air Force students.
