TALLINN (Sputnik) – The helicopter was claimed to fly with its transponder switched off, without a flight plan provided by its crew or radio contact maintained with Estonian air traffic control.
According to Tallinn, the Estonian Foreign Ministry summoned the Russian ambassador and issued a note of protest to the envoy in connection with the alleged violation.
"The Russian Mi-8 helicopter in the vicinity of the Vasknarva border post violated the air boundary of Estonia. It stayed in Estonian airspace for less than one minute," the General Staff told RIA Novosti.
"The Armed Forces’ helicopters did not conduct flights in the specified area on February 18," the Russian Defense Ministry’s press service responded.
