The UPI reports that “South Korea turned down a U.S. proposal to allow Japanese fighter jets to fly in South Korean airspace in September.”

“Seoul did not warm to the idea of aerial bombers of Japan’s air self-defense force joining U.S. and South Korean aircraft for a joint drill, Japanese newspaper Asahi Shimbun reported Tuesday.”

“But neither were South Korea’s F-15 fighter jets allowed to fly over Japanese airspace, while en route to a separate training mission in Alaska, according to the report.”
