“Inside information on a wondrously droll, highly classified yarn from WWII . . . A well-told, stranger-than-fiction tale that could make a terrific movie.” —Kirkus Reviews The plan: attach small incendiary bombs to millions of bats and release them over Japan’s major cities. As the bats went to roost, a million fires would flare up in remote crannies of the wood and paper buildings common throughout Japan. When their cities were reduced to ashes, the Japanese would surely capitulate . . . Told here by the youngest member of the team, this is the story of the bat bomb project, or Project X-Ray, as it was officially known. In scenes worthy of a Capra or Hawks comedy, Jack Couffer recounts the unorthodox experiments carried out in the secrecy of Bandera, Texas, Carlsbad, New Mexico, and El Centro, California, in 1942-1943 by “Doc” Adams’ private army. This oddball cast of characters included an eccentric inventor, a distinguished Harvard scientist, a biologist with a chip on his shoulder, a movie star, a Texas guano collector, a crusty Marine Corps colonel, a Maine lobster fisherman, an ex-mobster, and a tiger. The bat bomb researchers risked life and limb to explore uncharted bat caves and “recruit” thousands of bats to serve their country, certain that they could end the war with Japan. And they might have—in their first airborne test, the bat bombers burned an entire brand-new military airfield to the ground. For everyone who relishes true tales of action and adventure, Bat Bomb is a must-read. Bat enthusiasts will also discover the beginnings of the scientific study of bats.

More frisbees are sold each year than baseballs, basketballs and footballs combined. Yet these familiar flying objects have subtle and clever aerodynamic and gyrodynamic properties which are only recently being documented by wind tunnel and other studies. In common with other rotating bodies discussed in this readily accessible book, they are typically not treated in textbooks of aeronautics and the literature is scattered in a variety of places. This book develops the theme of disc-wings and spinning aerospace vehicles in parallel. Since many of the examples are recreational, anyone who enjoys these activities will likely find it profitable and enjoyable. In addition to spinning objects of various shapes, several exotic manned aircraft with disc planforms have been proposed and a prototypes built – these include a Nazi ‘secret weapon’ and the De Havilland Avrocar, also discussed in the book. Boomerangs represent another category of spinning aerodynamic body whose behavior can only be understood by coupling aerodynamics with gyrodynamics. The narrative, supported by equations and graphs, explains how the shape and throw of a boomerang relates to its trajectory. The natural world presents still other examples, namely the samaras or ‘seed-wings’ of many tree species, which autorotate during their descent, like a helicopter whose engine has failed. The flight performance of these spinning wings directly affects the dispersal and thus the evolutionary competitiveness of the trees concerned. Samara-type configurations are also considered for instrumentation and other payload dispersal applications. In short, the book discusses a range of familiar, connected, but largely undeveloped, topics in an accessible, but complete, manner. From the reviews of the first edition: "In his fascinating book Spinning Flight, Ralph Lorenz provides a rich feast of ... examples of spinning bodies ... . The book is well organized ... . The discussion in the book ... should be accessible to readers with some elementary understanding of aerodynamic principles. For the expert, the book is full of open problems ... . Its scope is extensive ... . In this respect, there may be something for everyone within its attractively designed cover ... ." (H. K. Moffatt, Nature, Vol. 444, December, 2006) "If you liked physics at school, then this book is for you. It concerns itself with flying objects that spin through the air, and even tells you how to impress your friends with the biomechanics of Frisbees. ... there is plenty of information at all levels, and the book has a wealth of detail that only an aerospace engineer like Lorenz could have come up with." (Len Fisher, BBC Focus, February, 2007)

It is no ordinary murder case that brings the famed French detective Monsieur Bencolin out of retirement, but one that involves a midnight rendezvous on a steamy Paris night, a broken love affair, and four different murder weapons found in the secret villa where the body is discovered. Rose Klonec, whose corpse bears the mark of a particularly horrible wound, had connections - and old lovers - throughout Paris, and soon the number of suspects grows to match the number of possible weapons ...
