In the 1980's I experienced the Ozark syndrome first hand... Midwestern cities like: ALO, FOD, MCW, STJ, COU, PIA and CMI all had mainline DC-9 flights. After the TWA takeover all these cities except for PIA and ALO (I believe) had thier mainline service yanked.
I also recall TOL, CAK and FWA losing UAL mainline service.
To most people, the sky is the limit. To those who love aviation, the sky is home
