The Caldwell Collection at Mustang Field is a celebration of aviation’s past and the people who made it soar. The nonprofit museum in El Reno was founded by Oklahoma City businessman and lifelong aviator, Tony Caldwell. Its mission is to inspire current and future generations through the beauty of flight and to honor the heroes who trained at Mustang Field before serving in World War II. 

Housed inside a fully restored 30,000-square-foot WWII hangar, the museum brings history to life with a timeless collection of Golden Age aircraft from the 1920s and 1930s, including rare examples of Waco, Travel Air, and Stearman biplanes. Visitors can explore aircraft that once trained pilots for war, discover how these planes were built and witness the art of restoration through Waldo Wright’s Flying Service, an active restoration shop on site. 

The museum regularly hosts educational experiences, fly-ins, and special events designed to connect guests with the legacy of flight. Founded in 2024 and brought to life in just 49 weeks, the museum stands as both a tribute to resilience and a living reminder of Oklahoma’s deep aviation roots. Admission is free but donations are appreciated. The museum is open on a limited basis by appointment or during public events.
