Chris Dieball, 28th Aircraft Maintenance Squadron crew chief instructor, explains the process of using a diesel generator to run the electronic components on the B-1B Lancer during maintenance to Airman Mark Vadnais and Airman 1st Class Christian Mains, 28th AMXS able chiefs, at Ellsworth Air Force Base, S.D., Jan. 21. When Airmen conduct maintenance on the B-1, the plane is hooked up to and runs off of a generator so as not to wear out the battery. (U.S. Air Force photo/Senior Airman Anthony Sanchelli)
