Historical Aircraft Squadron Museum is an all-volunteer nonprofit hangar museum at Fairfield County Airport in Carroll, Ohio, dedicated to restoring, displaying and operating former military aircraft and related equipment. Visitors can get close to aircraft and climb into cockpits, see military vehicles, uniforms, weapons and wartime memorabilia, and consult a library/reading room while volunteer craftsmen explain the restoration work. The museum’s hands-on collection and active-airport setting connect veterans’ history with practical conservation; school and group tours can be arranged. Visitor access is volunteer-led and should be confirmed with the operator before travel; the last airport gate leads to an active taxiway, so follow site instructions. Visitor address: Hangar B, Fairfield County Airport, 3430 Old Columbus Road NW, Carroll, Ohio 43112, United States.
