fiftyfour,
Swept wing airliners certainly are controlable in the stall. It is one of the first things covered on any type conversion. From your description you appear to be refering to the problem of spinning an airliner.
High tail airliners do have a problem in that the high nose attitued causes the airflow over the tailplane to come directly from the disturbed air of the wings, this leads to a deep stall.
However your post has nothing to do with the topic under discussion which refers to the vortex wake turbulence incident of AMR 587 which became an accident after incorrect pilot control inputs of the rudder.
