Sparks in the dark
Minot Air Force Base, N.D. -- Staff Sgt. Bruce Hills, 5th Civil Engineering Squadron, welds a support beam into a freshly cut hole for a new barn door for a hangar near the flightline here Sept. 6. The new barn doors will allow easier access to the hangar to store and remove snow clearing equipment for the flightline. (U.S. Air Force photo by Airman 1st Class Cassandra Butler)
