My book about my flying career has now been out for twenty months or so, to largely really positive reviews. But I am struggling with the fact that a few people that I know really well, still haven't read it. One of them was a pilot with me for part of the journey, and I would have thought he'd be among the first to do so, another is one of our close friends who loves aviation and everything associated with it, these are but two examples. I must say, it bugs me. What's it all about?
