Good that there is a factsheet out now.
But I am still surprised about some "facts".
E.g. the Last SSR position is followed by a right turn and then a left turn in the colors of a SSR track (or what do the colors mean?).
The yellow primary track starts after a gap in coverage more westerly.
We know from Flightradar24 ADS-B data, that the airplane made a right turn along the airway, indeed. But we did not know about the left turn, because ADS-B data ended before it started.
It MAY be Vietnam SSR data that helped here, but why is it not indicated as such?
Even if such details may not be too relevant to the public there are so many educated spectators of this event out here, that the investigators should treat any release of facts with utmost care and let outstanding people check it before its release.
Otherwise they may heat conspiracy theories, certainly unwanted.
