Query: A BOOK THAT DEFIES GRAVITY!

This is one one of the few but great books on my bedside table. Ever since a sentimental favorite book of mine. Eversince taking up and graduating Aeronuatical Engineering in college and a flying course after, this book together with the Bible was always on my flightbag thereafter. Now I even have a copy in my office. It supplied me with inspiration and motivation. It describes the joy in fying, the drama and excitement of flight and the philosophy of the air. A wonderful book and true adventure in a paperback book to aviators and non-aviators of all ages!
