An F-35A Lightning II arctic survival kit (left) and an Advanced Combat Ejection Seat (ACES) II arctic survival kit (right) lie on a table at Eielson Air Force Base, Alaska, April 24, 2019. Because the F-35A kit is smaller and shaped differently than the ACES II kit, trying to fit the same cold weather components has been an opportunity to innovate for Eielson’s AFE Airmen.
