It's the stuff British schoolgirls' daydreams are made of: Prince William helped save a 16-year-old girl after she got stranded off the Welsh coast. Wills, an RAF search-and-rescue helicopter pilot, was sent on the mission after surfers saw the teen trying to help her struggling 13-year-old sister, E! reports. The younger girl was already back on shore when the prince and his crew arrived, but her sister needed to be winched to safety from the water by the chopper piloted by William, notes the Daily Mail. Both girls are fine.
