The Kansas Aviation Museum will hold an open house Thursday to mark the opening of its Stearman Model 4 exhibit.
The Stearman Model 4 was developed from an earlier model, the C3, but fitted with more powerful engines that let the plane carry heavier cargo loads.
The plane was sold to commercial U.S. operators, such as Varney Air Lines and American Airways, which later became American Airlines.
In 1965, 13 planes remained on the U.S. Civil Register. They later went to private owners. A few still survive, including the plane under restoration at the Kansas Aviation Museum.
Never miss a local story.
The exhibit opening, which runs from 4 p.m. to 7 p.m. Thursday is free and open to the public.
