IMO, somatogravatic illusion is a red herring in this particular case.
I agree.
Of more importance, and to Lyman's observation of the crew's comment regarding having been "nose-up 'for a while' ", the inability on the part of all three crew members to assess as a stalled condition the high rate of descent which could not be arrested by pitching the nose up is, (as well as the absence of effective CRM and the lack of SOPs), set the pathway to this accident.
