They always emphasise the deliberate action bit but for the crew's reputational sake and keeping an open mind, I wish they'd include a caveat that this could just as easily mean somebody trying whatever they could to fly/navigate an aircraft facing considerable difficulty rather than, what seems to be in vogue, assuming foul play by the crew or a passenger.
Fortunately he went on to say they are keeping an open mind and are ruling nothing out until the aircraft and FDR/CVR are found.
