The first half of the 20th century saw the birth of the aeroplane and its development as an instrument of war and commerce. Within five decades, contraptions barely able to take to the air had given way to jet-powered aircraft, a rate of technological advance unparalleled in any other field. With carefully colourised images, this book chronicles the wide variety of aircraft produced in America before 1950, portraying them in their full glory once more.

The first half of the 20th century saw the birth of the aeroplane and its development as an instrument of war and commerce. Within five decades, contraptions barely able to take to the air had given way to jet-powered aircraft flying near the 'sound barrier', a rate of technological advance unparalleled in any other field. It was the period when Great Britain's aviation industry was established and grew to its zenith, fueled by the demands of two world wars and the growth of the airlines. These requirements generated a plethora of aircraft designs, some of which became house-hold names, while others failed to make the grade. British Aviation: The First Half-Century chronicles the wide variety of aircraft produced in Great Britain before 1950. With over 170 period images, carefully colourised, this book goes through the aircraft of the first half-century, portraying them in their full glory once more.

Landmark Papers in General Surgery will give surgeons, surgical trainees and other healthcare professionals an expert appraisal of key papers, and fast access to the evidence base behind current clinical practice in General Surgery. Each chapter draws together a fascinating selection of the most important clinical trials across every subspecialty within General Surgery, as selected and appraised by a panel of experts. Organized according to a common format, each discussion offers a clear structure by which to appraise the medical literature. Following a background summary of each trial, experts discuss the impact of the research and critique the methods used, giving the reader rapid understanding of the paper's place within the wider field of research. This emphasis on the tools of critical appraisal is enhanced by an introductory chapter equipping the reader with the skills required to knowledgeably appraise a research paper. For clinicians needing to keep abreast of the vast scope of medical research, this book will prove an interesting and timesaving resource, but it will also appeal to allied health professionals keen to improve the depth of their understanding of surgery. By bringing together the evidence base with expert guidance on critical appraisal, higher surgical trainees preparing for the academic and specialty sections of the FRCS exit examination will also find the text invaluable as a means of consolidating and nuancing their knowledge.
