In April 1978 , corps commander Vladimir Tsarkov ordered an Su-15 pilot to shoot down Korean Air Lines Flight 902 after the plane failed to respond to repeated orders to land , and approached the Soviet border with Finland . The Su-15 opened fire , forcing the plane to descend , and killing two of the 109 passengers and crew members aboard Flight 902 . The plane made an emergency landing on the frozen Korpiyarvi lake ( not to be confused with the Korpijärvi lake ) near the Finnish border
