2 -- No stick shaker on the other yoke... If they had known that they
were starting to stall as they decreased to V2, they could have
increased their speed and kept it from stalling and the roll developing...

Not sure exactly how the stick shakers in the big planes work, only
familiar with a C-172, which has only one port on the left wing to feed
what essentially amounts to a kazoo to inform the pilot that the plane
is about to stall. Did that particular DC-10 have a port on each wing,
and if so, would both ports have fed both stick shakers? If not, I
don't see how adding a second stick shaker would have necessarily
helped to recognize a stall, especially if only one wing was stalling
at the time.
