This new book is an in-depth study covering John K. "Jack" Northrop\s quest for a clean flying machine. Covered are: Northrop\s initial N-1M project, the N-9M, XP-56, through the B-35 project, B-49 project, and the huge bombers planned only on the drawing board.\nIncluded are over 300 black and white and color photographs, as well as drawings and statistical data on all of the Northrop flying wing and tailless aircraft.\nGarry Pape is also the author of Queen of the Midnight Skies: The Story of American\s Air Force Night Fighters. John and Donna Campbell are also the authors of Talisman: A Collection of Nose Art. Both books are available from Schiffer Publishing Ltd.

While successful developments in aviation receive considerable attention, the projects that failed or otherwise did not live up to expectations receive far less, if any, scrutiny. Typically, unsuccessful efforts are briefer in duration and have a less visible paper trail. Thus, while the literature is rich in success stories, we tend to “forget” or simply bury our failures. And, as one observer has suggested, “that there were failures, mistakes, and wrong turns reminds us that progress is not inevitable, that acknowledged error can be as instructive as success, and that roads not taken impose a price all their own.” Here, author Kenneth P. Werrell tells of a race to overcome obstacles—politics, resources, competing technologies, timing—in the quest to deliver quality, if not war-winning machinery. The focus of Air Force Disappointments, Mistakes, and Failures: 1940–1990 is on aircraft (e.g., bombers, fighters, transports) and missiles (e.g., cruise missiles, standoff missiles, ballistic missiles, surface-to-air missiles, air-to-air missiles). An intelligence system is also evaluated. These case studies give the context and details of the development, testing, and, as appropriate, operational service. Highlighting the problems and criticisms of these systems then provides an opportunity to determine what went wrong. The reasons for the failures of these systems vary from the obvious (money, delays, technical problems) to more complex reasons, such as the foe’s reaction, politics, new technologies, and timing. The tale of these disappointments is a heretofore untold story. These projects, in which the US Air Force stumbled, are outliers within the overall success of the service, and, fortunately, its successes outnumber the failures.

History of the Boeing 747 jet from the first design to becoming one of the most recognizable airplanes of today.

History and Evolution of Aircraft reviews the history of aviation from early history to the present day, including the evolution milestones of military aircraft, civil aircraft, helicopters, drones, balloons, airships, and their engines. It also provides the background and development of different types of aircraft, including manned and unmanned vehicles, aircraft carriers, fixed or rotary wings, air, sea, and amphibian flight vehicles. Covering current and developing applications of unmanned aerial vehicles (UAVs), the book highlights the prospects of future flying vehicles including automotives and jetpacks. It follows the transition from piston to jet engines that include shaft-based engines (turboprop, turboshaft, and propfan), turbine-based engines (turbojet and turbofan), and athodyd engines (ramjet, turbo-ramjet, and scramjet). The book explores flight vehicles’ technological advancements and evolution, including their geometrical features and performance parameters. It will also include nine appendices resembling databases for all types of aircraft. The book will be a useful reference for academic researchers and aviation, aerospace, and mechanical engineering students taking aerodynamics, aircraft structures, aircraft engines, and propulsion courses. Aviation history enthusiasts will be interested in the scope of the content as well. Instructors can utilize a Solutions Manual for their course.
