A colorful guide with a page or two dedicated to each aircraft.
A bit lacking in substantive details, and much of the text is written with superlatives, rarely mentioning flaws or operational issues.
However, it is a quick reference useful for reminding the reader of what a particular aircraft looked like and when it was flown.
One complaint is that while it is heavily illustrated, many of the photos are too small to pick out details such as markings. Many of the photos are not fully captioned leaving out information such as location or unit assignment.
A good gift for a young reader to spark an interest in the subject... not so much for the dedicated aviation enthusiast.
