TF2157 : Tattershall Castle When I visited this castle in c.1970 I was amused to see that a large delegation of Russian sounding names had all signed the castle's visitors book. The castle provided (as it still does) a lofty viewing platform over the airfield of RAF Coningsby, one of two QRA (Quick Reaction Alert) stations protecting UK air space (RAF Lossiemouth is the other). If these were indeed Russians, I like to think they had a great sense of humour!
