sky9,
As you rightly point out, Danny has indicated that he is awaiting the IAA's version of events.
My fear is that the IAA will, in a fashion they are well accustomed to, dodge the issue. This may well come about by taking five or ten years to investigate, conclude, or even acknowledge that it might warrant their investigation. Even if they do conclude an invetigation, they will no doubt hide behind the cloak of confidentiallity. This is their modus operandi.
I'm not suggesting that the IAA are any worse or better that other aviation authorities -for example, one only has to look at the continual friction that exists between the NTSB and the FAA.
Investigating a matter such as this should only take a few days - not months or years as everything is recorded. A/c operators, callsigns, crew details, RVRs, Radar plots etc.
It is not something subjective - purely a matter of record as to whether the aircraft that landed that evening at Stansted had adequate RVRs to commence and continue their approaches.
