During its first 20 years of operation Ozark had fulfilled exactly the promise that the local service airlines had been created for. It had started and proved a wide range of feeder services and grown demand to the point that it could sustain not just prop-jets but pure jets as well. Even better it had done so profitably and begun to wean itself off of subsidy and pick-up longer routes that the trunk airlines no longer wanted. All in all it found itself in good position to grow into the 1970s and face the challenges of deregulation to come.
Whenever I write a history of one of my US Douglas DC-9s in 1/400 scale there is a good chance that it will have ended up with Northwest, and even possibly Delta, through the continual mergers that constituted the deregulated aviation market in the USA during the 1980s. Following the recent release of a couple of nice NW nines by Aeroclassics in this post I'll quickly look at the livery transitions many of these Diesel Nines went through.
