Most of this discussion seems more AF447 related, given the lack of information regarding the accident this thread refers to.
tommoutrie makes the point that the issue today is more the recognition of the stall. Not the recovery.
Airbus and Boeing have tightened up their stall recovery techniques and they aren't really the issue here.
Certainly in a Boeing it is very simple:
Push down trim down until the stall indications stop.
Unreliable airspeed is also pretty clear cut now:
If in doubt straight away set a specific attitude and thrust setting then troubleshoot.
Recognition and prompt CRM and action is the issue, not the recovery technique.
