NOTE; NO FURTHER DISCOUNT ON THIS PRINT PRODUCT-- OVERSTOCK SALE -- Signficantly reduced list price The technologies for the reentry and recovery from space might change over time, but the challenge remains one of the most important and vexing in the rigorous efforts to bring spacecraft and their crews and cargo home successfully. Returning to Earth after a flight into space is a fundamental challenge, and contributions from the NASA Aeronautics Research Mission Directorate in aerodynamics, thermal protection, guidance and control, stability, propulsion, and landing systems have proven critical to the success of the human space flight and other space programs. Without this base of fundamental and applied research, the capability to fly into space would not exist.

Expanding the Envelope is the first book to explore the full panorama of flight research history, from the earliest attempts by such nineteenth century practitioners as England's Sir George Cayley, who tested his kites and gliders by subjecting them to experimental flight, to the cutting-edge aeronautical research conducted by the NACA and NASA. Michael H. Gorn explores the vital human aspect of the history of flight research, including such well-known figures as James H. Doolittle, Chuck Yeager, and A. Scott Crossfield, as well as the less heralded engineers, pilots, and scientists who also had the "Right Stuff." While the individuals in the cockpit often receive the lion's share of the public's attention, Expanding the Envelope shows flight research to be a collaborative engineering activity, one in which the pilot participates as just one of many team members. Here is more than a century of flight research, from well before the creation of NACA to its rapid transformation under NASA. Gorn gives a behind the scenes look at the development of groundbreaking vehicles such as the X-1, the D-558, and the X-15, which demonstrated manned flight at speeds up to Mach 6.7 and as high as the edge of space.

From the early machines to today's sophisticated aircraft, stability and control have always been crucial considerations. In this second edition, Abzug and Larrabee again forge through the history of aviation technologies to present an informal history of the personalities and the events, the art and the science of airplane stability and control. The book includes never-before-available impressions of those active in the field, from pre-Wright brothers airplane and glider builders through to contemporary aircraft designers. Arranged thematically, the book deals with early developments, research centers, the effects of power on stability and control, the discovery of inertial coupling, the challenge of stealth aerodynamics, a look toward the future, and much more. It is profusely illustrated with photographs and figures, and includes brief biographies of noted stability and control figures along with a core bibliography. Professionals, students, and aviation enthusiasts alike will appreciate this readable history of airplane stability and control.

To Be A Hero is a modern day setting allowing players to step into the roles of super-powered heroes and villains. In this setting, super-powered beings have existed throughout the ages and the classic conflict of hero versus villain has spurned on history's most defining moments. The battle of good against evil, justice against injustice, freedom against tyranny continues to be played out to the modern day with the player characters at the head of this epic struggle.The main book contains 7 brand new origins, the To Be A Hero's unique take on races. It also contains 6 basic classes, 20 all new prestige classes, as well as new skills and skill uses, feats, unique equipment, firearms and complete rules for super-powers and super-powered beings with over one hundred unique powers. To Be A Hero captures the essence of the super-hero genre and makes it playable and balanced in a way previously unseen.

"As human population continues to increase here on earth, congested streets and highways will abound at a rate well beyond our current plans for solution. Something is drastically needed to relax traffic congestion. An Aircar that con be housed in your garage; can takeoff "quietly" from in front of your house without a runway; and take you to work and back every day is conceptualized herein. A design specification for an Aircar is developed herein by first identifying the impracticalities of everyone having an Aircar for everyday use and then sets forth the technological means for overcoming each of the identified impracticalities. An Aircar design concept is presented based on a design specification. The one great importance of this book is that it identifies large number of applications currently under development, many of which have not been oriented toward any specific application.. Such technologies include nanotube materials, electrogravity propulsion, Lithium Air batteries, "free energy" electrical generators, plasma actuators for boundary layer flow control and noise reduction and electronic guidance and safety control. Thus, the development of the Aircar will bring to the entire aeronautical industry the full development of such relatively "far out" technologies."
