Re an earlier post, it’s not impossible that Lightnings were seen in Aden. Two development batch aircraft, XG333 and XG311 carried out the hot weather trials which took place between June and October 1961. As neither a/c was AAR capable, they were stripped of engines and some equipment, cocooned and shipped out on a freighter. In theory, the a/c should have not flown from Khormaksar as the barriers had been u/s for many months, a no-go situation for Lightning ops; fortunately, the barriers eventually become serviceable just before XG311 needed one in earnest on 27 Aug 61.
