A B-1B Lancer assigned to the 34th Bomb Squadron is refueled by a KC-135R during a training sortie over South Dakota, May 12. The KC-135R was piloted by members of the Wisconsin National Guard's 128th Air Refueling Wing. The team was here for ten days to enable Ellsworth's 24-hour surge operations.
