@ lena: that maybe an explanation regarding the TAWS, even when a strange one. it seems fact that this airport was not in the database.
The pilots at helm pretty much had no training and no qualifications to fly that plane, certainly not in these conditions and the only reason they were formally given that job was because there was nobody qualified left after the competent ones where "reassigned"
thats another interestong story. from the summary of the mak report all crew members were bloody fresh on the tupolev in their positions. and this piece of russian metal seems to be a pretty complicated, not easy to fly aircraft. in civil life you would for sure not go leftseat on a +100tons airliner jet with this experience on type.
the first consequence is that the whole military department of VIP flights seems to be cancelled after this and the president or chancellor of poland are now flying with lot airlines aircraft, operated by civilian pilots.
the second tu154 stays in hangar after a completely overhaul , with brand new engines. and the crashed one had some over 100 flight hours after completely overhaul.
