IMS Aero Clubhouse

By the time of its first automobile race meet - August 17, 1909 - the Indianapolis Motor Speedway had 41 buildings including this structure, a clubhouse for the Indiana Aero Club. Speedway President and Co-Founder Carl Fisher was also president of this organization. The clubhouse was high on the priority list of buildings to complete due to the first sporting event scheduled at the track: the national championship balloon races. This photo appeared in the April 18, 1909 edition of the Indianapolis Star above an article written by Fisher's balloon piloting mentor, Captain George L. Bumbaugh.
 
It is difficult to be certain, but the aero clubhouse might be one of the structures in an image from the first aerial view of the Speedway.
