N8444F / N509XJ (cn 7444) A Northwest two-fer', this Flagship CRJ is heading for its gate while a Mesaba RJ-85 (N509XJ, cn E2321) waits for its wheels-up time on taxiway Quebec. This is the first time N509XJ has appeared here, and unlike many of its stablemates it did not go on to fly with another carrier having been broken up at Calgary (YYC) after Mesaba retired the type.
