Though Mr. Wenne's book is obviously well researched, it seemed to overwhelm me at times. Perhaps if it had only covered the second world war years, I might have found it more informative.  He writes in a fairly conversational style, so overall I found MacArthur's Air Force to be a good piece of reference, and a nice addition to a military history bookshelf.
I received my copy through NetGalley under no obligation.

MacArthur’s Air Force: American Airpower over the Pacific and the Far East, 1941–51  is a fascinating read. I give it four stars.

Many members of RSL Clubs in Australia might be astonished by General Macarthur's and General Kenny's opinion of the Australians in the Air Force. They considered them pretty useless, apparently. Luckily, they improved!

However, this book is mostly about the members of the American Air Force in the Pacific War. Although I found the battle for New Guinea the most interesting part of the book by far, because I am Australian, the account is well-researched and detailed. However, it is very technical and a reader who knows about all the different types of airplanes will find it more rewarding. Also, I found all the different divisions of the forces a bit confusing.

The book begins slowly, but becomes more interesting.
