Wensleydale, your #10. Indeed the "Fog of War" ... i had a similar scenario in the early 80s at Waddington.
Exercise under way, Wing generating energetically, and the Stn Cdr is safe in the Ops Bunker. Just one snag ... dense fog descended, the type that only Lincolnshire seems able to produce. So, the convoys start moving from the ESA, and of course once moving they must NOT be stopped. But where are they? I ended up, on Storno on the Police channel, doing a distorted version of Local ATC with calls like "Have you passed the PAR yet?", and "The next convoy clear to leave the ESA.".
The Stn Cdr called me and asked why things were going so slowly. I gave him an informal summary of the weather conditions ... nobody can see ANYTHING out there!
