A thoroughly researched book, primarily about 19 Squadron based at Duxford. Full of the recognisable heroes of our greatest hour. It introduced me to many new pilots and auxiliary staff, provided insight to the challenges encountered with flying the Spitfire, particularly the cannons, and shone a light on pilots such as Douglas Bader and the political machinations behind the scenes. Reading the ebook version I found the way the photographs were laid out in the text confusing, and disruptive to the narrative. The very nature of the subject material did result in some mundane dialogue and there was a little too much repetition of some matters for my taste. That said, I do recommend this book for history and aviation enthusiasts. There are some real insights to be found.
