There used to be a tale that the reason for the Trident's offset nose gear was to avoid it hitting the centerline lights on every landing.
That said, I recall a cartoon in BA's house mag when Category IIIA certification (zero-visibility) was finally achieved. It was a solid grey panel captioned: "So we landed in zero visibility. What now?"
Apart from anything else, when the clag got that bad nobody could drive to the airport anyway.
