The US plan to convince North Korean pilots to defect for a cash reward was called "Operation Moolah"

Operation Moolah was a United States Air Force (USAF) effort during the Korean War to obtain through defection a fully capable Soviet MiG-15 jet fighter. Communist forces introduced the MiG-15 to Korea on November 1, 1950. USAF pilots reported that the performance of theMiG-15 was superior to all United Nations (U.N.) aircraft, including the USAF’s newest plane, the F-86 Sabre. The operation focused on influencing Communist pilots to defect to South Korea with a MiG for a financial reward. The success of the operation is disputable since no Communist pilot defected before the armistice was signed on July 27, 1953. However, on September 21, 1953, North Korean pilot LieutenantNo Kum-Sok flew his MiG-15 to the Kimpo Air Base, South Korea, unaware of Operation Moolah.
