William Wolf brings his meticulous research to describe the little known Douglas B-18 Bolo which was America's most numerous front line bomber at the time of Pearl Harbor. Over the years the story of the airliner turned bomber has languished in obscurity and the few articles on the subject in popular aviation magazines have emphasized its faults and maligned it as a budget bomber that had few virtues. Wolf's comprehensive book is the first ever on the subject and gives the reader the definitive description and appraisal of this neglected bomber's development, testing, manufacture, the aircraft per se, and combat experience.
