My Uncle, a former civvie watch manager at West Drayton, once related to me the tale of an old timer ATC who, on his retirement bash many years ago, came out with a few stories from his former life as an RAF navigator. Tasked with striking an Egyptian airfield at the start of the Suez crisis he couldn't find it, so his pilot suggested he call the airfield up for vectors, which he did and got a very helpful reply from the tower. He had the good grace to call the tower up at the start of the bomb run to say "Thanks for your help, but be advised this is an operational mission and we suggest you now take cover in the basement....."
