Arctic Aggressor Maintenance
EIELSON AIR FORCE BASE, Alaska -- Staff Sgt. Timothy Hiday, 18th Aircraft Maintenance Unit crew chief, inspects a speed break on an F-16 Aggressor Jan. 30, 2008, here. Eielson is currently receiving 10 of 21 Block 30s from Kunsan AB, Korea, in exchange for Eielson's Block 40s. The Eielson maintainers have to assure that the aircraft are able to withstand the constant arctic temperatures and do so by maintaining and changing out worn down parts when necessary.
