There was a visit by the Sultan of Oman's VC-10 (A40-AB?) some time late 70's or early 80's in connection with Rapier missile firings on the Hebrides range.
During the period 83 - 86 the largest visitors were a Swissair DC-9, Air Bridge Merchantman, and the occasional BAC-111 and Trident substituting for the usual BA 748. Also remember a Nimrod doing a touch and go one day which was impressive. There was 6000 feet of runway but only around 5400 usable.
