Several mentions have been made a 'deep stall' - why?
Wallybird, you need to do some reading. D.P. Davies, Handling the Big Jets" is a good starting point.
Just because it isn't a T tail doesn't mean that it can't get in a deep stall. Look at Gum's past postings regarding the F-16 deep stall. I just posted something yesterday on post stall lift coefficient curves. I'd define a stall that results in a flight path angle of 45 degrees to the vertical as pretty deep, particularly with an AOA of 61 degrees.
I know you are a Johnny come lately to the AF447 tech threads, but you need to get out of the rut of past habits and impressions. When you get into this stuff, it is pretty interesting and very educational.
