A common comment in this and the AF thread is: 'Why didn't they react to the STALL warnings?' The most likely answer is that the aural warnings were being sub-consciously filtered. When the brain is overloaded, the first sense our brains typically 'load-shed' is hearing. I can imagine that the pilots in both accidents would have have been very over-loaded trying to figure out what was happening and so their brains were not processing any aural information at all. This could also explain why the F/O didn't let go of his controller, rather than being a language problem, it might have been a 'I'm not hearing anything because my brain is over-loaded' problem.
