On September 6, 1976, Lieutenant Viktor Belenko of the Soviet Air Defense Forces defected by flying his Mikoyan-Gurevich MiG-25P "Foxbat" aircraft from near Vladivostok in the Far East of the Soviet Union to Hakodate Airport in Hokkaido Prefecture of Japan.

Viktor Ivanovich Belenko was a Russian-born American aerospace engineer and Soviet pilot who defected in 1976 to the West while flying his MiG-25 "Foxbat" jet interceptor and landed in Hakodate, Japan. George H. W. Bush, the Director of Central Intelligence at the time, called the opportunity to examine the plane up close an "intelligence bonanza" for the West. Belenko later became a U.S. aerospace engineer.
