Ah hah, that makes sense. Given that the stick shaker had activated,
they should have known it was a regular stall and performed a regular
recovery. A tail stall would have happened abruptly with no stick
shaker. Is that about right? Makes sense if so.

The thing though, at least according to the FAA video on tail stall thing
(it's on video.google.com, search for 'Tailplane Icing') it seems that
tail stall also manifests itself by odd pitch feedback on the yoke... I am
really wondering if there is any clear cut way to identify tailplane stall
from main wing stall as easily as you make it sound...
