The Air Traffic Control Officers in the tower have instrumented RVR readings which would have been passed to the pilot. They have no discretion on otherwise reporting visibility. "Ranger guy in the landy"?? I think you are some years behind the times if you mean the counting the edge lights!
Yes, we all know that. The point was that...
The only people who knew if there was thick fog on the approach/ threshold are the pilots on this approach
...is wrong.
As far as the Ranger guy in the Landy, as has been pointed out, at Southampton that is exactly what they do, up to date me. Not only that but they also 'range' around the airport and may have been sat near the threshold at the time. I don't know if he was, I don't know if he wasn't either. So again the above quote is wrong.
