This seems like a no win situation for the subordinate pilot. Grabbing the wheel of an aircraft while landing must have its own set of risks. We also only hear about the times when the subordinate pilot didn’t prevent a crash. Never hear about the times they were mistaken and did nothing.
A big part of the monitoring pilot's job is noticing when things have gotten too far and taking over controls. This does very much include scenarios when the pilot flying has fallen to tunnel vision, subtle incapacitation, and the continuation/sunk cost fallacy.
He doesn’t need to “grab the wheel”. Simply saying “go-around” would have been enough, it’s highly highly unlikely that the captain would have ignored that.
Yes I was wrong. Looking at the transcript that go-around call out was likely from the PF; that's where the data recorder indicates the brakes were released the throttle set to max for the go-around (and go back to braking only 4 sec later).
Still, the PM notified PF that they were going too fast many times during the approach. All warnings were ignored.
