Narrative:

Due to a hydraulic system failure, we had an unscheduled landing in dfw. As the captain anticipated, we landed without incident.(only 1 of the 2 system had failed, and in addition, there was still a standby system that was operable.) the captain did not request that we prepare for a planned emergency landing. He told me that he wanted to land the aircraft in dfw, because both he and the first officer felt that was the most prudent decision which they further confirmed with maintenance. Upon arriving safely in dfw, we had a change of aircraft, and proceeded to XXX, first officer.
