A US Navy veteran has started a search to track down a British World War Two veteran he met nearly 70 years ago, so he can return his Royal Air Force hat.
Byron Nilsson visited Portsmouth in June 1949 as part of a training tour with US Navy battleship USS Missouri, when he befriended British RAF pilot Ted Cooper.
Mr Nilsson was invited to Mr Cooper's home for dinner, where he met his wife and three-year-old daughter, and Mr Nilsson was intrigued to see the pilot's old RAF cap because the design was so different from his US navy one.
The pair decided to swap hats and, nearly 60 years after they met in 1949, Mr Nilsson, now 89, wants to find Mr Cooper or his family so he can return the blue cap.
