aterpster,
If you flew with the -7 engines they were no bargain. We had the -15s on the -200s IIRC. It was an improvement over the NE -200s which had the -7s.
Apparently there's more to the inlet story than I understood. I assumed the -100 had oval and -200 was round. I'm obviously misinformed. Now I am curious about why the difference.
