US Spy Plane Downed by North Korean ‘Jamming’ During March Drill

South Korea Report Says Plane Had to Make Emergency Landing

Reports from the South Korean military’s annual report to parliament revealed that on March 4, during the major US-South Korea annual drill, North Korea forced a US spy plane to make an emergency landing.

According to officials, the plane’s GPS system failed because of jamming signals broadcast in North Korea’s cities of Haeju and Kaesong. It was forced to land just 45 minutes after it took off.

The jamming also caused problems for South Korean naval patrol boats and people in the capital city of Seoul complained of poor cell phone connections during the drill.

Tensions between North and South Korea had been rising during the period, and South Korean officials repeatedly announced new military drills along the tense naval border for several months leading up to the incident.
