Its the captain alright. Based on my personal observation, they wont even do a straight visual approach, intercept downwind or intercept base in KLO even on a 9999 visibility. How much more let a beginner captain land an MPL on a captains runway? plus the factors that would make the captain decide to take over the control/perform a go around.
lastly, they have foms. If it was the FO who landed, they would have been fired right now and make news here!
