This is a very good fundamental book on the basics of medical problems and their impact on aviators. As a flight surgeon in the Air Force, this book is a must have in my arsenal of knowledge. If you are a flight surgeon or in the field of aerospace medicine at all, this is a good book to have for reference. This book does not go into detail about diseases themselves, but rather the impact that they may have on individuals who fly on a regular basis. For a much more detailed, comprehensive approach to things I'd recommend The Fundamentals of Aerospace Medicine by Dehart.
