I think that you are referring to Eagle/Vail. I am sure that NW
has never flown 57s out of Aspens, and I think that goes for the rest of the pack. The reason they use 146s is because of their great short field takeoff performance.
Airlink (XJ) still flew MSP
-ASE in before 9/11, I flew that route, and it was the most frightening landing I have ever had. We had a strong thunderstorm, major wind, and mountains all around. Just amazing, and unforgettable.
The New American is arriving.
