It must have been a charter. Salalah was not a scheduled destination in 59/61. We had a pilot on 152 who left the RAF, got his CPL and flew for an oil company in North Africa for a couple of years before he rejoined the RAF and was posted to Aden as an ops officer. We were very short of pilots on 152, so he was posted to 152. He flew for Gulf Aviation in his spare time for quite a lot of pocket money.
