"Midstate Takes Over Chicago Air", Chicago Tribune, October 21, 1986. Accessed February 1, 2024. "Midstate Airlines, a Wisconsin-based commuter carrier, has acquired a controlling stake in Chicago Air in a hostile takeover and installed a new management team at the rival short-haul carrier.... Midstate, which is privately owned, acquired a small equity position in Chicago Air earlier this year, when it sold several aircraft leases to the fledgling carrier based at Midway Airport. Chicago Air flies six F-27s on short-haul routes in the Midwest."
