In the mid-1930s, Waco was one of the most successful builders of personal and business airplanes in the country. Wacos were powerful, fast and a delight to fly, and they were expensive. That's why pilots coveted the graceful biplanes then, and now.
Waco — pronounced wah-co, not way-co like the city in central Texas — began life about 1920 as the Weaver Aircraft Co. After the relocations and management shuffles that were the norm for new airplane makers in that period, the company settled in Troy, Ohio. In the late 1920s, the company changed its name to Waco, probably as an acronym of Weaver Aircraft Co. Some say the name came from an airfield near Troy. Since Waco airplanes generate enough passion to support a museum in Troy dedicated to Waco airplanes, I am sure there are experts who are certain of the root of the name, but there is not necessarily agreement.
