Not too sure how come I missed this back in 2011, but here it is anyway...

Airmen and Aircraft from the 8th Fighter Wing at Kunsan AB, South Korea, deployed to Alaska for five weeks in the fall to participate in both the Red Flag-Alaska and Distant Thunder exercises at Eielson AFB, Alaska. This image, taken on 17 October 2011 shows six Wolf Pack jets on the Eielson ramp illuminated by the Northern Lights.

Red Flag-Alaska is a realistic ten-day air combat training exercise held four times a year. The focus of the exercise is to bring Airmen together from all different platforms and backgrounds to execute in a multi-service environment. Distant Thunder is a regularly scheduled multi-unit coalition exercise.
