And the question "were they landing" or "were they having a look" is also un-solved yet.
First news from all sources as we remember pointed in the direction "were landing, and by all means and in spite of any thing".
Then the official tune has suspiciously changed to "no, were not landing, were simply having a look down to 100 meters". This is very sweet, because it interestingly suits both sides - Russian aerodrome for allowing to land at all in that fog (it is disputable COULD they forbid them to do it, a legal nightmare. but from the moral point of view - Russian aerodrome should have placed a truck onto the runway and that's it no landing and forget about it, legally OK or wrong - that's for lawyers)
And it suits the Polish side as takes out of the hit any theoretically possible directions from higher chip commanders of all sorts on board.
So, how they got basically let's say it landing onto the Near Beacon - intentionally (mis-calculating their distance to runway) (attracted by other lights, as is said above) (or whatever)
or did they think they are just cruising above at 100 steady meters or more (altimeters game)
or what.
