Pontius
The French in CENTO?
I too was at Akrotiri, my time was 62 to 64. The three Canberra squadrons there were assigned to CENTO. I went to Karachi through Tehran on a CENTO exercise in December 63. But France was never a member of CENTO.
To quote Wiki: The Central Treaty Organization (also referred to as CENTO, original name was Middle East Treaty Organization or METO, also known as the Baghdad Pact) was adopted in 1955 by Iran, Iraq, Pakistan, Turkey, and the United Kingdom. In 1958, the United States joined the military committee of the alliance. It was dissolved in 1979.
