For what it is worth would suggest Bomber by Len Deighton 1943 Bomber command story - father thought very accurate as he flew at that time and was shot down and felt book captured the feel of the times very well. Red Storm Rising - Tom Clancy techno thriller late 1980,s, what if book. Both above fiction, but find any book by Max Hastings or Martin Middlebrook to be very good factual reads on their subjects. Also have to mention Ravens and Air America (can not remeber author currently).
