Funny at times and technical at some. This is the kind of book you would spend sometime with when you don't want to read anything serious.
There are many reference books out there on World War-II aircraft. This is one of the better ones.
Not as interesting as his other reference book, [b:Civil Aircraft|1538750|Civil Aircraft|Jim Winchester|http://d.gr-assets.com/books/1184905816s/1538750.jpg|1530905], but definitely a good inclusion to your 'reference books' shelf.
Best reference book about Civil Aircraft of the world that I have read. I still refer it whenever I want to know anything about any civil aircraft. A must have book for aviation enthusiasts or even for someone highly curious like me.
