Have anyone done some triangulation calculations to see if the top of the hill also was blocking the line of sight to the PAPIs
We need a North-South terrain profile to do this. We know exactly where the PAPIS are located to the left of RWY18 and we know that it was set at 3.2 degrees.
We also need to know whether the "runway in sight" call was a response to their first sighting of the runway or whether it was a response to 'reacquiring' a visual after temporary loss for whatever reason.
Was there an earlier 'runway in sight" call that hasn't been reported?
In one of the NTSB briefings we were told that the CVR group will sit down and transcribe every single voice and noise second by second, but prior to that they will inform the investigator of anything of significance that comes to their attention from a 'first listen' to the tape.
I'm assuming again I know, but in an investigation of a probable CFIT, any clues as to what that crew could or could not see is significant.
What we can probably draw from the call is that neither crew member was incapacitated prior to the first impact.
