Paul Marcello, 28th Bomb Wing historian, holds a photograph taken in 1944 that includes his grandfather, Alfred Marcello, and his B-17 aircrew. The group received its combat crew training at Ellsworth nearly 70 years ago. Studying his grandfather’s military career ultimately inspired Marecello to become Ellsworth’s historian.
