I see a little more explaining to do in the CA's near future. If he lost the RWY then it's an automatic missed approach.
As for the FLT Vis, if the PIC says he had it then he did. This can't be disproved, unless the FAA was in the jump, even then there's no proof.
Some may say, "why did he admit to anything?" The bottom line is that honesty usually leads to some retraining and not termination.
Honesty is respectable!
