In 1979 I flew from Dubuque, Iowa Chicago to catch a connecting flight. The airline was OZARK and they were Fokkers F27 high wing prop planes. These things rattle, banged and vibrated like crazy.
The trip back went to Peoria, Ill. then to Dubuque. I swore I would never fly again but I did.
My wife flew for United and they used to call OZARK, KRAZO Airlines.
