The Prince of Wales has paid a visit to his son the Duke of Cambridge at work.
Prince William showed Prince Charles around RAF Valley in Anglesey, north Wales.
Flight Lieutenant Wales, as the Duke is known in the military, showed his father one of the Sea King helicopters he captains during search and rescue (SAR) missions.
William, 30, has been part of SAR crew "C" Flight 22 Squadron at RAF Valley since January 2010 and last month qualified as an operational captain within the SAR force after two years flying as a co-pilot.
C Flight is responsible for rescues from ships in the Irish Sea and from the mountains of nearby Snowdonia and further afield.
Charles, an honorary air commodore, also met his son's colleagues.
