In the days of repeated and spectacular air conquests this book is startling to say the least. The author has presented the most complete case against aircraft, for either military or commercial purposes, and has collected an imposing number of testimonials to bolster up his case. The book is vigorously and brilliantly written, but is so obviously biased that it loses much of the power of conviction. On the other hand, as an antidote to excessive optimism it serves a good purpose. The introduction is by Arthur H. Pollen.
