Multiple diversions from MEL including self a few mornings ago due to fog, unforecast might I add. RVR's hovering around 300-500 m yet TDZ 16, and nowhere else, suddenly drops to 50, below Cat 3B minimum. Just seemed a bit odd.
Any suspicion that their transmissiometer was dodgy? If so, could be an expensive claim from several domestic and international carriers.
