Yes ... the METAR immediately before they landed was 175FG .... and it was 1100FG a half hour after they landed. it seemed that 200FG had been the thing driving it below minima which is what my tiny PPL brain is pondering over.
Nobody else landed for another 20 mins which tells me that the improvement was pretty sudden about 11.20 Z and the it was still below or close to minima when the BA landed.
This is more confused because an AF was happy to land CATIII at about 10.30 Z but told it was below minima.
Why AA came in as an emergency at 11.49Z after things were starting to get back to normal isn't explained.
What would I have done ? suffered the same dilema of an approach ban, holding time getting shorter but a forecast for rapid improvement.
