I guess the selective CVR out-takes should advise caution but there seems an odd lack of energy and activity about the whole thing. Hardly a time for quiet contemplation and one would expect the Cptn to become suspicious (rightly or wrongly) of the PF actions when things didn't go as expected and then forcibly intervene. No evidence of heads down activity as computers are re-configued or re-booted, not even a distracting light-bulb failure, so what were they doing - sitting largely in silence ? Were these men exhausted ?
