Absolutely agreed. At best, it would be a conscious (and correct) decision to prioritise 'aviate' over 'communicate'. Alternatively it could be that the crew became dumbstruck. The power of coherent speech, especially on the radio, quickly declines when adrenaline surges in a survival situation. The ability to listen goes early as well. Visual comprehension survives longest as stress levels increase, so at least Mother Nature has wired our brains in a way that suits the priorities of emergency handling!
