FWIW I flew in WH779 eight times between Feb and Oct 1982. The sorties were a standard mix of 100 Sqn target facilities fare - West Drayton PIs (yawn), Ex BROWN FALCON with Haircut 100 (aka OC 100 Sqn), an 8 Sqn MINIADEX, banner towing for 56 Sqn and 23 Sqn in Cyprus and a transit from St Mawgan to Wyton after a Wembury sleeve det.
