However if you're also working an inflight engine unstart which takes
precedence? Clarification: two engine unstart w/inflight emergency.
Quite a bit different from a situation that begins at cruise altitude
or with only *one* emergency rather than a sequence of events. As a
PAX I would rather know that the crew are concentrating on landing the
aircraft (ditching) as gently as possible.

That silly switch won't do a thing to save the buoyancy if the
fuselage is fractured by a rough ditching...a point one everyone seems
to miss.

I would hazard (grin) a guess that the final review will show them to
have maintained situational awareness with the concomitant priority
management.
