Mike,

You may not be aware that the flight instruments in newer transports are
electrically driven instruments; that is to say breaking the VSI or
other pressure gauge might work in a light plane but will not recover
the pitot-static system. These are driven by air data computers which
are connected to the pitot static system. There is redundancy built in
by multiple pitots, and multiple static ports. Unfortunately it looks
like they were defeated by a thorough job of taping.

You do have a good point in saying the plane was flyable by attitude and
power.  Perhaps more training for these types of situations can help.
