The outcome isn't surprising: this one looked like "pilot error" from day one.

From a frequent flyer's perspective, what's a bit disheartening about this report is that it confirms a long-held suspicion: that you're probably a little less safe flying a commuter "partner" than a mainline aircraft. It's hard to imagine these pilot/training errors occuring at CO. That said, experienced mainline pilots do -- on rare occasion -- make some very dumb mistakes. Like I recall some AA pilots taking an aircraft into a mountain side in Columbia a decade or so ago.

And, statistically, it's probably irrational to avoid commuter flights. If you're 99.99998% safe, do you need to be 99.99999 safe?
