An official said that the Russian plane flew to intercept about 20 feet (6 meters) from the US plane, and the confrontation lasted for about 9 minutes. Officials say the interception is safe, but not professional. However, a US Navy official told CNN reporters that Navy usually does not classify air confrontation in this way. The US Navy usually divides air interception into two categories: safety or insecurity. Zach Haller, a US naval spokesman stationed in Europe, declined to comment on the interception. He said: the United States Navy ships and planes often interact with other countries warships and planes. Information map: NATO F-16 fighter and Russian Soviet -34 fighter bomber interaction.
