Narrative:

Flight was very turbulent. After the initial beverage service; the purser came to the back and announced we had a problem with the hydraulics and needed to dump fuel. He said prepare for a hard landing. We picked up in between turbulence; in fact it was so bad that one of the liquor carts fell on its side in the coach galley. At one point he called and said we had 2 minutes prior to severe turbulence so I checked seat belts; collected any glasses; and made sure all loose bags were secure. We were in the aisle when there was not turbulence; talking and offering comfort as needed. Most of the inquiries were related to when they could return to the states and their connections out of our destination. The pilots told the problem that we had a problem with one of our systems that had 2 back ups to it; but due to this we needed to return to the departure airport. He said it would be turbulent as we needed to go back through the weather system we had just gone through to return and we needed to dump fuel before landing. We went back; but were too heavy to land so we circled above the airport with the landing gear down to burn more fuel. We landed without incident. Fire trucks were there just in case we needed them. After landing we discovered a thrust reverser was inoperative as well. Passengers were taken to a hotel and offered breakfast and lunch vouchers and a return to the airport for the next day. We left the next day after a hail and lightening storm delaying our fueling without incident. This flight was very turbulent as well. We landed a day late but safe.
