......the facts suggest this incident was much like the “perfect storm”. Poor weather, inadequate infrastructure, lack of communication and a failure to follow rules combined to risk ....
I disagree. Poor weather and inadequate infrastructure (CAT 1 only) are everyday occurances - nothing exceptional. This whole sequence of events was soley down to the decision of the Commander to commence/continue an approach below the legal minima. This is why we have rules - to protect the travelling public. Rules which can only be broken to prevent imminent harm to the aircraft or its passengers - not to keep the schedule running to time.
The final get out should have been at 1000' agl when a go-around would have broken the chain - assuming the RVR was below 550m at that point (probably was judging by METAR's).
The subsequent (in)actions on the ground demand only one solution.
