I was posted to 13 Sqdn detachment at Muharraq in July 1968 at that time 3/4 Canberra PR9's were based there with the rest of the squadron at Luqa, Malta.
A few months later all the aircraft and both air and ground crews where sent back to Luqa and the permanent detachment ceased as a result of the RAF draw down in that part of the world. After that time regular single aircraft deployments took place, I think operating from Oman.
