The 4th Fighter Interceptor Wing (FIW) was sent to Korea in December 1950 expressly to deal with the threat posed by the all-new MiG-15 fighter that had made its combat debut the previous month. It remained the sole Sabre wing in-theatre for a full year, its pilots tangling with Russian-flown MiGs up over the Yalu River on a near-daily basis. Through sheer skill and superior machinery, the 4th FIW prevailed, and the skies over North Korean remained firmly in UN control. This book includes numerous photos of aces and their aircraft, as well as extensive first-hand accounts.
