In my earlier post

I mentioned the possible death trap:
4. When in doubt about PAR directions to pull up and about the altitude
readings of GPS and ALT, they may have used the radar altimeter readings.
Those showing them the bottom of the valley instead of alt. above threshold.
5. When the altimeter reading started to rise quickly, it was too late.
In the first pictures of this analysis (1. and 2.) you can clearly see the valley
I am referring to.
This "death trap" has been mentioned before by the Russian pilots current to this airfield.
