Caldwell Collection at Mustang Field

Caldwell Collection at Mustang Field is a nonprofit aviation museum at El Reno Regional Airport in El Reno, Oklahoma, opened in 2025 in a restored 1943 World War II training hangar. The collection celebrates Golden-Age aviation and the pilots trained at historic Mustang Field through preserved and flying antique aircraft, ground-support vehicles, aircraft stories and live restoration work operated with Waldo Wright’s Flying Service. Representative collection aircraft include 1920s–1930s Waco, Travel Air, Stearman, Fairchild, Great Lakes, Curtiss-Wright and other vintage types; the museum also offers a library and virtual-tour interpretation. The operator homepage currently lists Wednesday–Friday 11:00–16:00 and Saturday 10:00–14:00, free admission and walk-ins welcome, while the dedicated Making a Visit page says visits are limited, volunteer-hosted and by appointment and that unscheduled visits cannot be accommodated; confirm current access before traveling. The museum’s visitor guidance directs guests to the designated east-side entrance at 6600 S Mustang Field Road, Hangar 3, El Reno, Oklahoma 73036, United States, and warns that restoration and flying activity can change what is on view.
