I wonder what his personal library already has?
Something like "The Mighty Eighth" by Roger Freeman would be a good one because it's such a great over all view of the 8th AF operations out of England. Lots of images as well. And it opens the door to go chasing so many other books.
"Air Command" by Jeff Ethell would be a good starter too with all that great color photography of the airwar in Europe.
There are so many good biographies it's tough to pick just a couple, but I suppose "Wing Leader" by Johnnie Johnson is right near the top of the list.
My personal favorite WW2 aviation book is "Nanette" by Edwards Park about his P39 flying days with the 41st FS, 35th FG 5th AF in the Pacific. A scared, average Joe, doing the best he can in a less then the best plane. (Guppy35 is a result of that book. Guppy was a nickname of a P38 pilot buddy of Park and the 35th was the FG.)
If I was forced to survive on two books the rest of my days it would probably be Mighty Eighth, and Nanette.
There are so many great books out there though it's tough
