That facility you see was actually the ops and maintenance building for
Southern Airways. They were formed in 1946 and flew routes from Memphis and Atlanta. On July 1, 1979 Southern Airways was merged with North Central Airlines of Minneapolis and Republic Airlines was born. At the time of the merger, Southern operated DC-9s and metroliners. In 1973 Southern purchased several of the original Delta DC-9s that were some of the first off the production line. In October 1980, Republic purchased Hughes Airwest(Another DC-9 operator) and then Republic was absorbed by Northwest in October 1986.
