In 1933, the Ohio Oil Company leased the
Rummel Airport for ten years, renaming it
Findlay Airport. Plans at the time called for the construction of and runways in an X layout. Operation of the airport was taken over by Ray B. Vaughn in mid 1941 after the previous manager, Mike Murphy, was called up by the
Army Air Corps. The Ohio Oil Company moved to a new hangar at the airport in November 1946. A project to lengthen the runway to and add hangar space was underway in December 1953. The construction of twelve new hangars was almost complete in December 1959.
Lake Central Airlines scheduled flights to Findlay from 1961 until 1965-66. In the late 1960s, Northern Airlines provided commuter service to Findlay. The airline provided 6 weekday departures (fewer on weekends). Three of the flights were nonstop to
Cleveland Hopkins International and three to
Lima, Ohio, continuing to
St. Mary's, Ohio and
Dayton, Ohio. Due to the lack of a passenger terminal, the airport's facilities were deemed to be inadequate for scheduled air service in 1961 and again in 1964.An effort to obtain a state grant for such a building failed in 1970 when it was ruled that public funds could not be used for a privately owned airport. Another attempt begun in 1973 was successful, after it was agreed to build the structure on county-owned land. Dedication of the Hancock Air Terminal was announced in October 1975. The city considered purchasing the airport in 1992. The airport was operated by
Marathon Oil Company until 1993. The following year, over twenty companies were vying to operate the airport and a extension for the north-south runway, which would partially offset a reduction in length, was being planned. Crow Executive Air of
Metcalf Field was selected in January 1995. However, the offer was rescinded five months later when the city instead favored
Cooper Tire. Crow subsequently sued for breach of contract. The airport received a grant for a runway and taxiway extension in August 2000. After initially being allocated $4.95 million from the
federal stimulus in April 2009 for the construction of a taxiway, a government watchdog said the airport should not receive the funding because it does not see enough traffic. The airport did receive nearly $2 million from the US Department of Transportation in 2022 to build a new aircraft parking area, allowing the airport to receive larger aircraft, improve drainage, and improve pavement markings. An adjacent tie-down apron and the taxilane to the airport's t-hangars were also upgraded. Some federal funds were provided by the
Bipartisan Infrastructure Law, and additional funds were provided by the State of Ohio and the city of Findlay. ==Facilities and aircraft==
