I was seven years old when I first read this book. It spurred me on to get a pilot's license and I have been enjoying the rewards of soaring flight ever since. Their book is ripe with vivid imagery and packed with fascinating information on the pioneers of soaring. It is very easy to read and equally hard to put down once you've begun. Etched in my memory all this time, I have been searching for a copy for over 41 years(I wish I had told the library that I had lost it and just paid the fine!) I would recommend it as mandatory reading for anyone interested in the history of gliding and soaring. It is extremely well written and well illustrated. So much so, that I can still remember certain passages and illustrations to this day. If it were possible, I would give it an eleven on a scale of 1-10.
