Para...your assuming the capt flew an unstabilized approach, so much so that he should have gone around based on the 600 hr FO making that call. We know that captain landed the plane, how bad could the approach have been?
Not trying to disparage the FO, but I tend to agree with other posters on this forum that I tend to side with the 20,000 hour captain before I would the 600 hr FO when it comes to judging the difference between a stabilized approach or not.
