NORTH KOREA: US Military Plane Forced Down By North Korean Electronic Attack. “A US military reconnaissance plane came under electronic attack from North Korea and had to make an emergency landing during a major military exercise in March, a political aide said Friday. The aide said the plane suffered disturbance to its GPS system due to jamming signals from the North’s southwestern cities of Haeju and Kaesong as it was taking part in the annual US-South Korea drill, Key Resolve.”
