Who is congesting airliners’ general practitioner in the Baltic?

.ON APRIL 29TH Finnair, Finland’s nationwide airline, mentioned that it will put on hold flights to the asian Estonian area of Tartu for a month. Recently two aircrafts were actually required to reverse after their general practitioner indicators were disrupted. Family doctor playing has increased greatly in the Baltic region over the past 2 years.

That is behind it and also how dangerous could it be actually?
