I don't remember by now anything, but I think I read in the very beg., when the controller was interviewed, that the plane was on course fine steady and all proper height, as I understood, at 2,000 m away off. (to confirm that last known "OK" height is important, I think. requires reading all over anew :o(
And by 1,050 it was already cutting a tree (at 8?) metres height, in the area of the Near Beacon, where it should have been at 60 m height.
Someone on the other blog has calculated that it was then going down at 6.5 sec/metre and found it very ? abnormal quick.
If it helps anyone. with anything.
Also as I understood something was made known officially, on the Polish side, that the plane was measuring its height in metres.
And the lady who made it known said that on whatever it is they were using m to another ? measueremnt is re-switched easily by one button, shouldn't have been a problem if they wanted not metres but something else.
And that one of the last crew members certainly was at this very Northern Smolensk the prev. week bringing in PM Tusk.
And that he knew 100% about that? hole, preceding the road.
The other pilot, who flew with the crew member the previous week, to this Northern airport, carrying Polish PM, was interviewed and said all this.
