North Korean Defector Delivers MiG-15 to US, Leading to Key Intelligence Gains
DEFENSE
On September 21, 1953, North Korean pilot No Kum-sok defected to South Korea, flying a MiG-15. His arrival provided the U.S. with essential intelligence, as the Air Force had sought an intact MiG since Operation Moolah was launched in April 1953.
No flew from Sunan Air Base to Kimpo Airport, undetected due to radar maintenance. Following his landing, he informed U.S. pilots about the MiG's performance and weaknesses during debriefings, which informed American tactics against Soviet jets.
No received $100,000 reward after initially being unaware of it, later becoming a U.S. citizen and aerospace engineer. The MiG was studied until a landing accident in 1956.
