Poor energy management early in the approach and get-there-itis put them in their graves. Had the overrun been flat farmland they’d probably have got away with either mud in the tyres or an embarrassing shudder to a halt and a lot of explaining to do.
If you were being very generous then you could argue that the automation didn’t help them by continuing to track the false GS but there were plenty of clues that all was not going to plan.
The high terrain could have been anticipated by the MSA and presumably minimum vectoring altitude charts, plus the STAR laid out well in advance the descent profile they’d have to hit. There were no big surprises here, apart from the temperature adjusted lowest cleared altitude.
Not a good show.
