Who is sticking airliners’ general practitioner in the Baltic?

.ON APRIL 29TH Finnair, Finland’s national airline company, stated that it would certainly put on hold trips to the far eastern Estonian city of Tartu for a month. Recently 2 airplanes were actually forced to turn around after their family doctor signs were actually interfered with. GPS playing has actually raised dramatically in the Baltic location over recent pair of years.

Who is behind it and also just how unsafe could it be actually?
