The first aviation activity in Indiana County took place in the early 1920

The first aviation activity in Indiana County took place in the early 1920's on the Bennett Farm. In 1929, Indiana County opened its first airport, Hamilton Field, located along the East Pike. After World War II, it became clear that the airport needed to expand. The Indiana

County commissioners acquired 208 acres of land northeast of the Borough which is the site of the current Indiana County Jimmy Stewart Airport. It was officially opened on September 3, 1951.

Over the years, several notable improvements have occurred at the airport. There have been ongoing construction projects to increase the number of hangars to house the aircraft based in Indiana. There have been many improvements to the runway lighting system, as well as snow removal capability to allow all-season operations. The airport installed an Automated Weather Observation System (AWOS) in 1995, enabling pilots and others to receive timely and accurate weather information for the airport. In 1997, a modern new terminal building was opened, which houses administrative offices, a pilots' lounge and flight planning area, and a conference room. The installation of a new fuel tank farm has enabled the airport to provide jet fuel (JET A) in addition to conventional aviation fuel (100 LL). Also, a maintenance hangar and new T-hangars were recently constructed. Currently, the airport is in the midst of a major runway extension project that is expected to be completed around 2010.
