In this book, Tim Jenkins examines the factory worker poisonings and suspect government procurement procedures that resulted in Allied success in the air during First World War.The early development of aircraft during World War I was an important yet dangerous part of the war effort seen in the First World War and although many descriptions of daring aerial combat have been written, the risk to those involved in the manufacture of such machines remains less well known. Tetrachlorethane, a poisonous solvent contained in aircraft dope, was responsible for a number of civilian deaths in aircraft factories and although the British knew the substance to be lethal, they were much slower than their American and German counterparts in sourcing alternatives. In this groundbreaking book, Tim Jenkins explores the use of Tetrachlorethan and brings to light the concerns and warnings voiced by the international medical profession. His examination considers the government's reasons for its use of the poisonous solvent to create a compelling yet scholarly account which takes in corruption, negligence and wartime manufacture. This book will be vital to scholars studying military production during the First World War.
