The Secret of Flight
by Johan Hoffman, Johan Jansson, Claes Johnson
Number of pages: 128
In this book we present a mathematical theory of subsonic flight based on a combination of analysis and computation. By computing and analyzing turbulent solutions of the incompressible Navier-Stokes equations for slightly viscous flow subject to force boundary conditions, we uncover a mechanism for the generation of substantial lift at the expense of small drag of a wing, which is fundamentally different from that envisioned in the classical theories by Kutta-Zhukovsky for lift and by Prandtl for drag.

The purpose of this advisory circular is to make amateur-built/ultralight aircraft pilots aware that test flying an aircraft is a critical undertaking, which should be approached with thorough planning, skill, and common sense.

The book is written in the simplest possible language, and contains not a single formula. It treats the principles of flight and the problems involved in the mechanics of the aeroplane, demanding only the most elementary knowledge of arithmetic.

This book tells the story of the origins and development of the United States Air Force's space program from its earliest beginnings in the post Second World War period to its emergence as a critical operational presence in the Persian Gulf War.

Thought-provoking ideas, views, and speculative reasoning. The book itself is divided into three parts: National and Global Dimensions of the Space Age; Remembrance and Cultural Representation of the Space Age; and Reflections of the Space Age.
