One reasonably regular task for the Whirlwinds when I was there in 1966 was to provide transport for a small section of RAF Regiment who would be put down beside the road, usually between the causeway and Sheikh Othman where they would carry out an impromptu roadblock, to search cars and occupants for arms and explosives. I went on a few of these and never found anything. Since we did not have any female assistance we were obviously unable to search any women in the cars we stopped and as they were often in the head to toe burkha, who knows what might have slipped through?
Incidentally Shack 37 I was there on 37 (Field) Squadron, RAF Regiment, which led to some confusion with two squadrons of the same name on the base!
