I'm not aviation expert, but it looks that some 'well known facts' do not fitt to strict logical path.
1. Pictures in Picasa album have coordinates

2. First birch tree top was cut approx at 2.5 km distance from runway.
3. Tower operator states, that he noticed deviation from glide slope when a/c was at 1.5 km distance from runway.
4. Is that logical ? At 2.5 km. plane had to be about 130 metres high on 3 deg. glide slope. What is expected descent rate - 5 m/s ? It translates to 26 sec. to descend and forces me to expect that warning must have been issued at least 10-15 sec. earlier.
Also to cover distance 2.5-1.5 km= 1km with 300 km/h approuch speed there is another 11 sec required.
So, it it was PAR approuch, tower response came 20 sec to late, if my math is more less right.
How to explain that ?
What, if the pilots calculated the risk but their risk equation included timely warning ?
Not PAR approuch ? But tower issued warning to abort landing - they had some data available.
Very strange.
