This book is concerned with the sport of soaring, mainly with the mathematical basis of sailplane design and operation. It does not tell the beginner how to fly, but it will give an experienced pilot some background, with historical notes showing how ideas have evolved and could develop in the future. Some of the material is taken from OSTIV (Organisation Scientifique et Technique Internationale de Vol a Viole) publications and from Technical Soaring, neither of which is readily available to the general public, including papers by the author and others. Extensive references are provided in each chapter.

The classic first analysis of the art of flying is back, now in a special 50th anniversary limited edition with a foreword by Cliff Robertson. leatherette binding, and gold foil stamp. Langewiesche shows precisely what the pilot does when he or she flies, just how it's done, and why.

Here is the little-known history of Otto Lilienthal, a daring man whose more than 2,000 successful flights inspired the Wright Brothers and other aviation pioneers. In 1862, balloons were the only way to reach the sky. But 14-year-old Otto Lilienthal didn’t want to fly in balloons. He wanted to soar like a bird. Scientists, teachers, and news reporters everywhere said flying was impossible. Otto and his brother Gustav desperately wanted to prove them wrong, so they made their own wings and tried to take flight. The brothers quickly crashed, but this was just the beginning for Otto, who would spend the next 30 years of his life sketching, re-sketching, and building gliders. Over time, Otto’s flights got longer. His control got better. He learned the tricks and twists of the wind. His flights even began to draw crowds. By the time of his death at age 48, Otto had made more than 2,000 successful glider flights. He was the first person in history to spend this much time in the air, earning the title of the world’s first pilot and paving the way for future aviation pioneers.
