Book excerpt: The beginning of World War I saw thousands of army and navy aviators who needed specialized clothing that could not be purchased off-the-shelf. During World War II pilots and crews flew countless missions in extreme conditions, from the Arctic to the South Pacific. Through both wars, providing suitable clothing to personnel aboard many different types of aircraft proved a monumental task. This book documents the development, testing, manufacture, procurement and utilization of flying apparel and accessories worn by American airmen around the world between 1917 and 1945. Among the garments explored are various types of flight suits--including heavy winter shearling suits and electrically heated suits--flight jackets, flotation gear, headgear, handwear and footwear. With appendices that include contemporary brochures detailing the care and maintenance of flight clothing, this study provides a thorough exploration of a rarely examined aspect of military history.
