Having grown up in west Michigan, I was well familiar with the "Blue Goose" of North Central. I always thought that it was a pretty neat airline. I remember traveling to Washington, DC in 1971 when on a scholarship program as a high school student--this is what commercial air travel was like back them when you lived in a small market. The NC flight was something like MKG-LAN-DTW-CLE, changing in Cleveland to UA for the CLE-DCA flight (the NC flight originated at ORD and stopped at MKE before crossing Lake Michigan). NW flew the 50 seat Convair turbo prop which had very comfortable seats and was extremely noisy.
