Packed with never-before-seen photos, plans and meticulous new digital artwork, this is the first history of the USAAF's futuristic World War II prototype interceptor, the XP-67 "Moonbat". The series of X-planes that sprang from the US Army's Request for Data R40C, focused on high-altitude, high-speed, long-range bomber interceptors. Among these aircraft was the McDonnell Aircraft Company's first ever clean sheet design, the XP67. Its futuristic lines promised performance that it was ultimately unable to deliver, but development was still underway when disaster struck. Just before Army performance demonstration flights were scheduled to begin, an engine fire destroyed the only XP-67 prototype, leaving a host of unanswered questions about what might have been, and leading to decades of continuing fascination with the XP-67 among aviation buffs and aircraft modelers. The authors of this book have uncovered new sources of information and a wealth of photographs and line drawings that document not just the XP-67 but also its immediate precursors within the McDonnell Aircraft design community, as well as alternative configurations for unbuilt variants aimed at different missions. Packed with unpublished photos of all stages of construction including key airframe changes made after initial flight tests, showing in detail how the final configuration was evolved, this volume finally provides clear focus on a story that has long been shrouded in mystery.

The revolutionary X-15 remains the fastest manned aircraft ever to fly. Built in the two decades following World War II, it was the most successful of the high-speed X-planes. The only recently broken 'sound barrier' was smashed completely by the X-15, which could hit Mach 6.7 and soar to altitudes above 350,000ft, beyond the edge of space. Several pilots qualified as astronauts by flying above 50 miles altitude in the X-15, including Neil Armstrong, the first man on the Moon. The three X-15s made 199 flights, testing new technologies and techniques which greatly eased America's entry into manned space travel, and made the Apollo missions and Space Shuttle viable propositions. With historical photographs and stunning digital artwork, this is the story of arguably the greatest of the X-Planes.
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.
The McDonnell F3H Demon is probably the least remembered modern Naval fighter, even though it was our first true all-weather missile fighter. When the weather prevented the agile F8U, F4D and F11F from flying, the Demon could still be launched. A glamorous plane the Demon was not, primarily due to its lack of performance. The F3H remained underpowered throughout its career, so much so that it was tagged by fleet pilots as the "lead sled."
American Secret Pusher Fighters of World War II analyzes the state of military aircraft procurement just prior to the start of World War II. It provides insight into the difficulties encountered by America's air services in dealing with an isolationist Congress and a limited mindset in the Army, which was seemingly indifferent to the aeronautical progress being made in Europe by the British and Germans. The book then focuses on the three winners of the 1940 fighter competition - the Vultee XP-54, the Curtiss XP-55, and the Northrop XP-56. Each of these radical designs - engine in the back (aka Pusher) using small canards in front, or, in the case of the XP-56, essentially a flying wing, used non-strategic materials and were developed in secret. At the time, the aerodynamics of these aircraft far outpaced engine development. In addition, this book details the technical difficulties of mating an advanced aircraft design with inadequate engine development.
The XB-40 and XB-41 were secret, little-known experimental modifications of the B-17F and B-24D, respectively, into heavily-armed bomber gunships sometimes referred to as “bomber escorters”. They were developed during early World War II in response to the lack of a USAAF long-range fighter aircraft able to escort and protect regular B-17 formations making the round trip from Britain deep into Germany. Using many formerly-classified documents from his large microfilm collection, William Wolf presents their previously-unpublished history. It describes in depth for the first time the politics and development and associated problems of both escorter types. Unfortunately, these “protecters” were found wanting in several ways - after the addition of guns and ammunition they became overweight and tail-heavy causing center of gravity problems and each encountered numerous delays in the development and delivery of their various armament additions and improvements, particularly the Bendix chin turret. In the end, the YB-40 participated in only 14 lackluster operational service test missions during mid-1943 before being withdrawn from service. The XB-41 Liberator never saw operational testing before also being cancelled for its poor performance. The failure of the gunship concept left a huge hole in the capabilities of the Eighth Air Force. Their failure, however, spurred the adoption of the Merlin-powered P-51 Mustang, the outstanding escort fighter that was key to Allied victory in the air war over Europe.
The Dornier Do 335 was conceived as a high-speed, all-weather fighter, and represented the pinnacle of piston-engined aircraft design. The Do 335 was a big aircraft, weighing just over 10,000kg when laden with fuel, equipment, and pilot, yet powered by two Daimler-Benz DB 603 engines, it was capable of reaching a maximum speed of 750km/h at 6400 meters, making it the fastest piston engine aircraft produced in Germany during World War II. Some forty aircraft were built between late 1943 and the end of the war, and it was intended to deploy the type as a day fighter, bomber, night fighter, bad weather interceptor, and reconnaissance aircraft, all of which were intended to incorporate the latest armament, bomb sights, communications, and radar equipment, as well as an ejector seat. Featuring archive photography and specially commissioned artwork, this is the full story of the aircraft that the Luftwaffe hoped would turn the tide of the war.
As Europe plunged into World War II, Hitler ordered the development of a hi-tech secret weapon capable of taking the war across the Atlantic – the Messerschmitt Me 264. Chosen from designs for an 'Amerika Bomber' tendered by Messerschmitt, Junkers and Focke-Wulf, this ultra-long-range aircraft would be capable of attacking cities in the United States. Just one month before the attack on Pearl Harbor and the American entry into World War II Hitler was promising, privately, to wage a 'new war' against the USA after his victories in Europe. Dazzling digital artwork and 50 rare archive photographs perfectly complement the detailed analysis offered by Robert Forsyth as he examines the development, intended role and influence of the aircraft that Hitler planned to use to bomb New York City.
