On September 21, 1953, U.S. airmen at Kimpo Air Base near Seoul, Korea, were startled to see landing a MiG-15, the most advanced Soviet-built fighter plane of the era, piloted by Senior Lieutenant No Kum-Sok, a 21-year-old North Korean Air Force officer.

Once he landed, Lieutenant No found that his mother had escaped to the South two years earlier, and they were soon reunited. At his request, No came to the United States and became a U.S. citizen. His story provides a unique insight into how North Korea conducted the Korean War and how he came to the decision to leave his homeland.
