In 1950, the RCAF was heavily involved with the transportation of personnel and supplies in support of the Korean War. The RCAF was not involved with a combat role since no jet fighter squadrons capable of the type of combat required in Korea were yet in service, and capable fighter squadrons that later did become operational were allocated to NATO duty in Europe. Twenty-two RCAF fighter pilots, however, flew on exchange duty with the USAF in Korea. Several, including Squadron Leader Joseph A.O. "Omer" Levesque, and Flight Lieutenant E. A. "Ernie" Glover scored air-to-air victories.
