Aero Linx: WACO Historical Society With the help of the WACO Historical Society (founded in 1978) members and many generous donors and supporters, Historic WACO Field opened in 1997. The field consists of a 77 acre site and features a 2200 foot runway (2000 feet usable) south of Troy, Ohio. Historic WACO Field is maintained by WACO volunteers and is constantly receiving upgrades and improvements, but we are always in need of additional volunteers to assist in the upkeep of the site.
