Having been a part of the Fifteenth Air Force in 1944, author Bill Hess has written the definitive account on 'his air force', featuring photographs and illustrations throughout. Although the Fifteenth Air Force was dismissed as 'minor leaguers' by the Eighth Air Force, strategic bombers from this outfit had done a 'major league' job on Axis targets in southern Europe following its formation in Italy in November 1943. And the heavy bombers employed by the Fifteenth were of course the venerable B-17 and B-24. At its peak strength, the Fifteenth's B-17 force comprised six groups of four squadrons each, all controlled by the 5th Bomb Wing.
