PigBoat...yup...but someone beat me to it...A nord converted to pratt and whitney engines later called the Mohawk conversion. I was original USAIR (still am) hired in 88. Very proud of the original USAIR. It was three years before I ever saw an MEL sticker on one of our DC9's...they took really good care of everything...company MX at every RON. things changed when we had to compete with the cheapos. Still a good place with good folkx (at least on the east side...don't know the westies too well).
I flew that Jetstream with tthe turbomecca Astazou engines...by the way, all those funny names from turbomecca were famous mountain peaks in europe.
