Over the past few months I've been desultorily packing up boxes full of books in the attic to take to Half Price Books or Goodwill. Basically, anything I'm unlikely to read again for entertainment or use for reference is a likely candidate for passing on. While sorting through stacks, look what I found!
The Complete Fighter Ace is just a really cool book. It's organized chronologically, with sections covering World War One, the interwar conflicts, World War Two, the air war over Korea, and post-Korea jet combat. Each section has lists of the aces from each participant nation, with a short bio of a few of each country's aces, including lots of lesser-known ones. There are descriptions of tactics and techniques as they evolved, with plenty of diagrams and illustrations. Highly recommend. I'm shelving my copy where I can find it more easily in the future.
