This book is the generic flight manual for the B-24D, dated 15 September 1942. The H model on the book's cover photo was a poor choice (or ignorance) by Periscope. When I purchased it I was looking/hoping for something covering the later and more widely used G, H or J models. This book does have some good information in it, and if nothing else gives the reader an appreciation for how un-ergonomic and purely utilitarian combat aircraft were at the time. Crew comfort and efficiency were certainly not worth much in the designers' eyes. But if you are looking for some good details on operation of all the aircraft's systems including armament and interior layout, this isn't it.
