Both USA and Britain did this.
America used the U-2 at that time.
The countRy is Russia(Soviet Union). In 1983 a Russian military jet shot down a Korean Airlines commercial airliner.
The U-2 plane is a spy plane. In the Cold War between the US and the Soviet Union one plane from the US crashed in the Soviet Union. This caused a great deal of tension seeing as how the American president of the time was denying the act of spying on Russia at the time.
That was a U-2, flown by Gary Powers. He was shot down over the Soviet Union on 1 May, 1960.
The United States used the Lockheed U2 and Convair PB4Y Privateer to gather intelligence about the Soviet Union and China before the advent of spy satellite technology.
