VOR/DME and INS still work fine, landing is ILS (still preferred and much more accurate than GPS), just need to intercept the beam

Europe seems to have convinced itself a decade or two ago that Russia wouldn't fuck up European navigation "just because," which was stupid, Russia promptly declared war on European GNSS

The world decided that russia was ok after the USSR dissolved, a small mistake

Soviet-style behavior seems to be genetically hardwired into anyone and everyone in Russian leadership

I saw another poster seeing that it was the airport affected?

the whole area was affected Russia has been jamming GPS in central and eastern Europe for years/decades now Baltic Sea maritime navigation is especially persistently affected

I've read that the Kaliningrad jammer does GPS spoofing too. Maybe the pilots did not want to take th risk of having systems spofed without it being noticed? This was in speculation as cause of the DHL crash in Lithuania ( Later ruled out)
