Things have to be explained

This is the beginning of our 50th Anniversary of joining the RAF. The date of our arrival at RAF Cosford was 6 May 1965 and we spent 12 months training to be either Photographers (Ground, Air, developing, analysing etc.) or Telegraphists (Morse Code, Teleprinters, Power generators, etc.) I was a telegraphist and proudly wore the 'Sparks' badge for the next 12 years.
