Hagerstown Aviation Museum preserves more than a century of regional aviation and Fairchild Aircraft history in the historic 1943 Fairchild Flight Test Dome Hangar at Hagerstown Regional Airport. Its growing collection includes Fairchild aircraft, military and civilian aircraft, artifacts, living-history displays and restoration projects; current exhibits include the Fairchild RC-26B and A-10 Warthog when available, while special events may host visiting warbirds. Visit schedule, admission and holiday closures are operator-controlled and can change; check the current plan-your-visit guidance before travel. Free parking and personal photo/video are allowed, but some hangar areas are not climate-controlled. Group tours of 10 or more require advance reservation on the museum’s designated days, and aircraft or event availability varies. Current address: 18450 Showalter Road, Building 8, Hagerstown, Maryland 21742, United States.
