O'Hare International Airport
The airport was constructed in 1942–43. It was made as a manufacturing plant for airplanes during World War II. The site was chosen for its proximity to the city and transportation. The two-million square-foot (180,000 m²) factory needed easy access to the workforce of the nation's then-second-largest city, as well as its extensive railroad infrastructure. Orchard Place was a small nearby farming community.
