U.S. entry in WWI spurred rapid
aviation expansion in the country.
Due to city's strategic location to
military airfields, railroads, and
industry, U.S. Army opened an aviation
repair depot here in early 1918. 809th,
810th, 811th, and 821st Aero Squadrons
repaired, modified, and tested
training aircraft and engines. The
Speedway provided hangars and a
flight test field.

Speedway area became an innovative
aviation hub during WWI. Work at the
depot increased pilot safety and
aircraft structural integrity. Italian
Pomilio Bros. Corp. developed aircraft
here for the Liberty engine produced
by Nordyke & Marmon with parts by
Allison Experimental Co. The depot
repaired 313 planes and 350 engines in
1918. By fall 1920 it ceased operations.
