An F-16 Aggressor lands on Eielson's flight line for the very first time which will be used for training purposes in exercises such as Red Flag- Alaska Jan 20. About 40 F-16s fighters are being permanently swapped this week between the 354th Fighter Wing at Eielson Air Force Base, Alaska, and the 8th Fighter Wing at Kunsan Air Base, Republic of Korea, in an effort to put newer, more capable aircraft on the Korean peninsula.
