Hey, they're descendants of the Caribou, Buffalo, Twotter, and Dash 7, what do you expect? Runs in the family. Hereditary bushwhackers.
Yup, indeed. We've had them for 15 years and they get flogged, yet there's nary a scrap of corrosion on them. The ATRs however...Hmmm. We got our first '600s two years ago and they are going through their first C-Checks and they're finding corrosion in them already. I've never worked on Twotters. A mate has, says they're the business.
