The drop in airspeed was unnoticed, and the stall seemed
to catch them completely by surprise.


I wonder what the stall warning was doing all of this time?

It appears that it was the stall warning (stick shaker) that the
captain (pilot flying) reacted to.

The reaction was to immediately pull back pretty hard
quickly precipitating an actual stall. 80% power was also
selected immediately. The stick was held back pretty much
until impact.

There is a simulated video on the NTSB web site. Web site
seems a bit busy at the moment.

They appear to have been decelerating towards 119 knots
in preparation for final approach when the stick shaker went off
unexpectedly at 139 knots. They may have forgotten that the
stall warning was set to trigger at a higher than normal
airspeed due to the aircraft being configured
partly for icing conditions.

If the reaction to the stick shaker had been to merely
stop the deceleration there would it seems have been no crash.
