Maybe PF though his PFD was lying to him.
In any case, it is tragic that the lack of deceleration when he briefly deployed the speedbrakes didn't start someone thinking. Instead the lightning bolts sparking between the PM and PF by then washed away the ability to form that type of question.
Incidentally, has anyone considered the short period that PM was awake as a potential reason for his lack of assertiveness. Perhaps he just didn't trust himself yet?
