The "lack of language knowledge" was also mentioned in many Polish news.
As I mentioned above also after landing the military were not able
to communicate with the crew properly, until a passenger
was let into the cockpit to translate...
Regarding radar services at EPPO, I can only confirm,
flying there VFR few weeks ago, that also FIS has no services
available, even for the VFR advisory service, carrying
no responsibility for separation...
So probably the "uncertified" radars are also shut down,
as "Stuck_in_the_ATR" suggested...
