Who is actually obstructing airliners’ family doctor in the Baltic?

.ON APRIL 29TH Finnair, Finland’s national airline company, mentioned that it will put on hold flights to the far eastern Estonian metropolitan area of Tartu for a month. Recently 2 aircrafts were actually forced to reverse after their family doctor indicators were actually interfered with. GPS playing has actually enhanced greatly in the Baltic region over recent two years.

That is behind it and also exactly how hazardous could it be actually?
