rebukes the PF for trying to extend the speedbrakes.
According Interim 3 CVR transcript:
2:12:04 to 2:12:07 "The airbrakes are controlled and
deployed" and PF comments "I have the impression that we have some crazy speed..."
That has occurred at about FL300 descending. What else than thinking of overspeed makes a pilot deploy airbrakes?
