This book is centered around the author’s father’s World War II diary. Robert C. Sage was a B-17 pilot who flew twenty-nine missions out of Thurleigh, England, as a member of the 8th Air Force, 306th B.G., 367th B.S. (“The Clay Pigeons”). It is accompanied by four chapters describing his life before and after the war, as well as archival photographs, appendices, and extensive notes identifying the individuals and events mentioned in the diary (April-September, 1944, including D-Day missions). This record has lain dormant for over sixty years and was recently uncovered. It is a valuable contribution to the history of the Mighty Eighth and its participation in World War II.
