The more I think about this.. the more I think.. how is it possible? Even if the PF ( fatigued, 3.00 am in the morning) had severe spatial disorientation during the take off roll.. how is it possible that the PM just let it happen? It appears he just sat there and watched the end of the runway appear at a great rate of knots.. and did nothing, up to and including, “ I have control”. This could make a great CRM study.
