Where can I find reference material to find a certian commuter aircraft used by Piedmont or Southwest Airlines probably in the last 20 years. It was a twin engine high wing aircraft, real boxy looking. Any help would be appreciated. Sorry for the dumb questions.
However, I’m not sure it would have been a DO228. Piedmont (actually operated by a commuter carrier such as Henson) had Shorts 330 and Shorts 360 aircraft, looking similar to the Skyvan posted above. Southwest has never had any commuter aircraft.
