I guess a couple of thoughts/ideas gathered from various places would be in place:
1. altimeter change is claimed to be made by pilots to "shut out" TAWS calls.
2. pilots were probably looking out for VMC to land, so the callouts from 3rd crew member were probably their only reference to altitude; worth to notice they were made based on radio altimeter (so 100 was way below 100)
3. No reaction to go around is very similar to previous disaster - C295M at Miroslawiec in 2008 - going below clouds for visual again.
4. Russians do take a bit of blame from themselves, but only a BIT. After watching the video, all forums/comments from pilots is pretty much what I feel - they've got what they've asked for, unfortunately.
Best regards,
Adam
