Query: A GREAT SEQUEL TO A GREAT BOOK..........

This book is a follow on to a previous bookm by Mr. Haugland, " The Eagle Squadrons", about American fighter pilots in the RAF in 1941-42. The Eagles reverted to U.S. Army Air Force control in the spring of 1942, and this book takes up their story from that point.Many of the pilots transferred out of the unit, voluntarily or otherwise, some even stayed with the RAF for the rest of the war. This book covers the 4th Fighter Group, the Eagle's U.S.A.A.F. sucessor, and the stories of those pilots who moved on to other units. Like the 1st book, this one is a " must have " to any WW 2 aviation buff.
