Further to our post yesterday about Billy Colson, on Black Thursday he had taken the place of Ivor Glyn Stephens as bomb aimer on the Mackenzie crew. Stephens would survive the war, as would Keith Kirby, who had been in the aircraft with Billy Colson when it crashed. Severely injured, he seems to have made a full recovery. He married in a double wedding in which Glyn married Keith’s sister and Keith married her best friend.
