In the 1980s, I was in the tower at Taif as a build up of incoming heads of state was happening. While chatting with the controller, the pilot of the inbound president of Sudan's 707 was heard calling Jeddah, saying the president wanted to do a tour around Jeddah, taking in the sights. As it was afternoon when nothing much happened in Jeddah, this was OKayed and the pilot called Taif to tell them he was on his way. The tour around Jeddah must have confused the pilot as initial approach to Taif had him heading for a landing on the main Jeddah to Riyadh road which happened to be parallel to, but displaced by half a mile from the active runway!
