Editor's Notes and Comments:
Product Description:
Fallacies of popular aerodynamic teachings based on misapplication of Bernoulli's law are revealed, and more appropriate description of wing operation is presented in terms of Newton's laws. Explanation of wing operation is then expanded to include how and why performance is affected by design variables of span, chord, aspect ratio, camber, washout, taper and sweep. Aircraft configuration is also discussed.

It's overall a good book, I would have given it a 3.5 star if it's an option. The structure is clear with easy wording at entry level, suitable for beginners. However I was a bit disappointed in the lack of maths in 3D modelling and other later parts.
Another great drawback is the lack of neutrality of the author - the Newtonian and Kutta explanation of lift could be essentially the same. They are just discribing different stages of the recirculation.
So if you want to do a physics coursework on airfoil lift, or just have some nerdy fun, this is definitely a good choice.

The title is great, but the book disapoints. It appears to be self-published, not that that is necessarily bad, but Craig could use an editor. Craig's explanations of lift are badly written, confusing, and disorganized. There are better explanations of lift in terms of Newton's laws than what is provided in this book on a variety of websites. Save your money and instead google for "wing," "circulation," "lift", "newton" and other similar terms. Or check out NASA's explaination of lift on their website. I plan to get rid of my copy of "Stop Abusing" at the very first opportunity.

It is very unfortunate that there is so much misinformation circulating about the physics of flight. In a way a strange state of affairs, since this subject is a rather simple application of mechanical laws (unless one wants to perform detailed mathematical analysis). Many of the phenomena associated with flight can be confirmed at home by simple experiments. The author begins the book with an honest endeavor to debunk some of those troublesome theories. Strangely, he also attacks well established physics and mathematics used to analyze and design airplanes and then starts to develop his own theories. The book is riddled with a mixture of correct statements, misinterpretations, wrong or questionable math and simple falsehoods that pull into question the authors grasp on the subject matter. In order to enable potential readers to arrive at their own conclusion I would like to present two points in detail.
Recirculation: The author postulates a flow of air circulating around the wing in such a way that it flows from front to back on top und from the back to the front at the bottom of the wing. In other words he states that there is a flow of air below the wing that is moving faster than the airplane against the oncoming mass of air. At very first I thought I was misinterpreting the explanation, but the author's statements about the function of the stall warning device leave no doubt. This can be disproven by simple experiment. A thin sheet of plywood or a sheet of cardboard can be used as wing (give it some camber if you think this is necessary). Several pieces of thread a few inches long can be attached at various locations to the surface at one of their ends using pieces of tape. They serve as very good indicators of the flow pattern. Air flow can be produced by walking or holding the board out of a car window. It can be easily observed that the air flow stated by the author does not exist.
Derivation of the Law of Bernoulli: On page 141 beginning with formula 13-1 the author derives the law of Bernoulli. The math presented here is the standard way of deriving this law and can be found in many textbooks on aerodynamics and the result is correct. However, anyone equipped to follow the math can easily see that it is based on the observation of a mass element with a given frontal area and extent in direction of movement. This is fundamentally at odds with the problem discussed (the Venturi Tube) and illustrated in Figure 13.2 on the same page. From the illustration it is clear that the area S changes continually and from the constant mass flow throughout the tube it also follows that the extent of the mass element in direction of flow must change as well. Since the math does not fit the problem it is fundamentally flawed. It is not the correct description of the conditions inside a Venturi Tube. Obviously the author fails to recognize the discrepancy, which leaves serious doubt about his understanding of the law of Bernoulli. At the very least he teaches something wrong.

More than 100 years after the Wright brothers very first motor flight still 99%+ of people will be taught a false explanation how aerodynamic lift is generated. Mr. Craig is to be named as one of the few exceptions, who do it in a correct manner.
I am curently writing a book in German about the same topic but with a wider range. I agree with almost the entire book, but will write some aspects even more understandable for the layman as well as the educated one.
Anyway, it is a great help to know that the problem is attacked elsewhere according to the true physical priciple rather than to easy perceivable falsehood.

Perhaps the worst book relating to aircraft design that I have ever bought. Many flaws. Wish I could get my money back for this one. I'd give it zero stars if I could.
