I have been sent the above pic by a friend. He does not know from whence it came so if I am infringing the owner's copyright or sensibilities I will of course remove it. He thinks it is an ATC summer camp at Thorney Island. It is of special interest to me as XV 186 was the first 'K' I flew in on the OCU on Feb 19 1968.
The Captain was John S.
I am sure smudge will have something to say about the props !
