Russian border guard helicopter violates Estonia’s airspace

HELSINKI (AP) — NATO member Estonia says a Russian border guard helicopter violated the airspace of the Baltic nation over the weekend, and Russia’s ambassador was summoned and given a note over the incident. Estonia’s military said in a statement that the Russian MI-8 helicopter entered the country’s airspace in southeastern Estonia in the Koidula area — not far from the Russian city of Pskov — without permission on Saturday evening.  The helicopter was in Estonian airspace for almost two minutes, Estonia’s military said, adding that it hadn’t presented a flight plan, had its transponder switched off and failed to maintain radio contact with Estonian Air Navigation Services.
