The plot has most definitely been lost guys. Talking about recovery from 10nm at 300kts - this is a commercial airliner with paying passengers on board, so let's get out of test pilot thinking, eh?
I do believe that this is a good case for a crm type discussion and not a good deal else. To any of us who do this for a living, it's painfully obvious to see that a go around was the only option or ask for extra track miles before it gets to that stage. To those who keep blaming the f/o, I'd be interested to know what you fly and how long you've been doing it. For an inexperienced pilot to deal with this in real time is a classic crm dilemma - how far do you let it go ? This type of problem has been around since the very beginning of 2 crew operations with an experience gradient on the flight deck. Maybe the f/o concerned is a complete muppet but then I wasn't there and I don't know him.
We all get checked on our flying ability in the sim and a limited amount of crm, mostly relating to 'stock' scenarios. How anyone reacts when it goes wrong for real is a different matter. Whilst some intervene asap, others sit on their hands and may well do so until the self preservation alarm bell starts ringing.
300kts at 10nms !!!! Oh dear.....
