Im surprised the 170 never got the opportunity to fly into Aspen. Always wondered how the plane would do there.

I would assume the "special" go-around procedure would be just to bring the flaps from 5(or flaps full) to flaps 4 (flaps 5 is the same degree setting as 4 but flaps 4 are for takeoff & flaps 5 are for normal landing). Maybe someday.....
