Narrative:

Our flight had a loss of hydraulic pressure situation. The captain had me work the loss of hydraulic fluid and/or pressure checklist with the flight engineer while the captain flew the aircraft with no autopilot; because of the hydraulic pressure situation. The captain elected to turn around and go back to our departure airport; because of the longer runways. I contacted the center and told them our intentions to turn back. We were given a descent; I can't remember exactly what altitude it was but it was in the mid 20's. During the descent the captain missed the level off altitude by 400 to 500 ft. He corrected the altitude and we finished the flight.
