How did actor Kevin Stoney get his scar?

Snippet on IMDB: "Kevin Stoney served in the Royal Air Force during the Second World War, where he trained as a pilot and was sent to the Middle East. However, he crashed so many planes that he had to be reclassified as a navigator." ... perhaps?
I saw that, but he didn't have the scar earlier in his his film career.
