Remoak, you might not recall the last time a wheel departed a 737 axle, but I do remember a southwest 737 landing with it's rh gear in flames...this week. Personally, I see a pretty smooth turnaround of between 50 and 70 q400s a day, of which I am rarely called to. The landing gear was always suitable for the dash, it's just required fine tuning with a course of modification programmes. I have every faith in this aircaft, and still happily fly on it
