I tend to your school, Evanel. What makes it worse is that we do not know for sure whether this Metroliner was Cat I or II - some are some are not; nor the crew; nor the R17 ILS that day, and as NoD and others have tried gently to point out, BBF has (I assume) NO IDEA of the actual RVRs passed during the approaches. As for the 'not changing RVR' (thanks, BBF, for that) would that be the METAR RVR that 'changed' from 375 to 600 over the period of the crash? Does BBF use the METAR RVR for his 'approach ban' decision, perhaps?
The sooner these posters recognise that the ATC given RVRs, a/c, crew and ILS states should be a matter of record and stop 'hinting', the better.
