Aden Airways (which was a BOAC associated company) finally gave up the unequal struggle at the end of June 1967 having suffered several of their aircraft being blown up. I can remember seeing two DC-3s in BASCO colours at Khormaksar before we finally left Aden in November 1967. I don't think the two companies were ever really in competition. My memory is that Aden Airways were quite happy to get out of there and probably wished Brothers all the luck in the world.
