@bubbers44:
Experience is certainly a factor, but there are other more complex issues involved.
The PNF didn't actually have a great deal more hours under his belt than the PF, but it seems apparent that he had a better handle on the situation at first. Regardless of experience, some people handle pressure and abnormal situations better than others - and the initial difference in approach between the two FOs seems to highlight this.
What's more disturbing is the complete lack of CRM throughout the sequence and the fact that upon his arrival, the Captain got bogged down in a reactive mode rather than taking charge and pooling all the information as to what happened before his arrival.
