Who is actually sticking airplanes’ general practitioner in the Baltic?

.ON APRIL 29TH Finnair, Finland’s national airline, stated that it will put on hold air travels to the eastern Estonian area of Tartu for a month. Recently two planes were actually pushed to reverse after their GPS indicators were disrupted. General practitioner jamming has actually boosted dramatically in the Baltic location over the past 2 years.

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