Very disappointing; was excited to try the many different original designs. However written instructions and diagrams are not clear at all, by far the weakest of the three books we got. My guess is that it is only for very experienced makers; not recommended for those without much familiarity with the principles of paper airplane construction (i.e. kids and their unsuspecting parents).

This book has the most horrible directions and diagrams immagineable! There is no glossary of terms the author uses in his instructions (what in the world is an "accordian fold" and how does one "accordian-fold the bottom sides"? What is a "bottom side"?) and the diagrams are poorly labelled. Children and their parents will end up with nothing but frustration.

This is a great book on paper airplanes and some origami paper toys. It is mostly about airplanes and there is airplane after airplane on page after page. No matter what you want your airplane to do, glide for long distance, do tricks or just plain look cool, it is in this book. Unlike some other books on this subject it does not have any premarked papers secured to the inside of the book that you can rip out and fold. On the other hand, these planes use ordinary paper and have such good illustrations that you can make them without any premarked patterns on the paper. I love the book. I've folded most of the planes and flew them. It makes me a popular person at children get togethers and allows me to be a child again once in a while myself.
The only thing that I don't like is that it has no theory of paper airplanes. If you fold one and it does not seem to be acting right then there is nothing in here that might teach you how to correct the problem. If you want to learn the aerodynamics involved in making a paper airplane act the way it does, how lift and drag affect the flight, etc, then this book is useless to you. But if you just want to follow the diagrams and make some great airplanes that are consistently fun, then this is your book.
Just "plane" fun.
