Wichita ? The Kansas Aviation Museum in Wichita is opening a new exhibit featuring the iconic Stearman Model 4D airplane.

The museum plans a free open house from 4 to 7 p.m. Thursday to celebrate the opening of the exhibit. The museum says visitors can learn the history of the plane and the story of its restoration. They can also view the restoration of the plane now under way at the museum.

The Stearman Model 4D was a biplane first built in the late 1920s with a deeper fuselage and more powerful engines than earlier models. It was sold to commercial operators.

About 41 of the planes were built before production ended. Thirteen remained on the U.S. Civil Register in 1965, including the Model 4D now under restoration at the museum.
