Although radar had existed for several years prior to the eighties at Blackpool Airport in the form of what I remember as a Plessey 424 very narrow beam primary radar, I believe that the original modern set-up (primary only) was a Cossor 787. In latter years this was replaced by a primary-only Plessey AR 15, which was amalgamated initially with the feed from Warton's then Marconi 511 SSR. After storms damaged Warton's radar head the decision was taken to use the secondary feed from the conveniently-situated St Annes Radar Station across the road. Since this feed was routed initially through West Drayton before reaching Blackpool Airport the whole affair became extremely expensive to run, costing I believe over £1000000 per year.in Approach, the radar displays were Cossor rasterscan, initially circular and latterly rectangular, full colour.
