In this book, Dr. Andras Sobester reviews the science behind high altitude flight. He takes the reader on a journey that begins with the complex physiological questions involved in taking humans into the "death zone." How does the body react to falling ambient pressure? Why is hypoxia (oxygen deficiency associated with low air pressure) so dangerous and why is it so difficult to 'design out' of aircraft, why does it still cause fatalities in the 21st century? What cabin pressures are air passengers and military pilots exposed to and why is the choice of an appropriate range of values such a difficult problem? How do high altitude life support systems work and what happens if they fail? What happens if cabin pressure is lost suddenly or, even worse, slowly and unnoticed? The second part of the book tackles the aeronautical problems of flying in the upper atmosphere. What loads does stratospheric flight place on pressurized cabins at high altitude and why are these difficult to predict? What determines the maximum altitude an aircraft can climb to? What is the 'coffin corner' and how can it be avoided? The history of aviation has seen a handful of airplanes reach altitudes in excess of 70,000 feet - what are the extreme engineering challenges of climbing into the upper stratosphere? Flying high makes very high speeds possible -- what are the practical limits? The key advantage of stratospheric flight is that the aircraft will be 'above the weather' - but is this always the case? Part three of the book investigates the extreme atmospheric conditions that may be encountered in the upper atmosphere. How high can a storm cell reach and what is it like to fly into one? How frequent is high altitude 'clear air' turbulence, what causes it and what are its effects on aircraft? The stratosphere can be extremely cold - how cold does it have to be before flight becomes unsafe? What happens when an aircraft encounters volcanic ash at high altitude? Very high winds can be encountered at the lower boundary of the stratosphere - what effect do they have on aviation? Finally, part four looks at the extreme limits of stratospheric flight. How high will a winged aircraft will ever be able to fly? What are the ultimate altitude limits of ballooning? What is the greatest altitude that you could still bail out from? And finally, what are the challenges of exploring the stratospheres of other planets and moons? The author discusses these and many other questions, the known knowns, the known unkonwns and the potential unknown unknowns of stratospheric flight through a series of notable moments of the recent history of mankind's forays into the upper atmospheres, each of these incidents, accidents or great triumphs illustrating a key aspect of what makes stratospheric flight aviation at the limit.

Rockets and Revolution offers a multifaceted study of the race toward space in the first half of the twentieth century, examining how the Russian, European, and American pioneers competed against one another in the early years to acquire the fundamentals of rocket science, engineer simple rockets, and ultimately prepare the path for human spaceflight. Between 1903 and 1953, Russia matured in radical and dramatic ways as the tensions and expectations of the Russian revolution drew it both westward and spaceward. European and American industrial capacities became the models to imitate and to surpass. The burden was always on Soviet Russia to catch up—enough to achieve a number of remarkable “firsts” in these years, from the first national rocket society to the first comprehensive surveys of spaceflight. Russia rose to the challenges of its Western rivals time and again, transcending the arenas of science and technology and adapting rocket science to popular culture, science fiction, political ideology, and military programs. While that race seemed well on its way to achieving the goal of space travel and exploring life on other planets, during the second half of the twentieth century these scientific advances turned back on humankind with the development of the intercontinental ballistic missile and the coming of the Cold War.

Aeronautics and Space Flight Collections serves as a narrative survey of important sources and library holdings concerning Aerospace History in the United States with reference to other countries. It brings to life the human fascination with flight.

In this superb little book, written during World War II, historian, sociologist, and novelist H.G. Wells (1866-1946) contemplates the belief systems, prejudices, and institutions that have brought humankind to a dreadful impasse, where it stands at the brink of destruction - or of a new beginning. In his lucid summary of modern ideas concerning the fundamentals and ultimates of existence, Wells points out how absurd and outmoded religious beliefs, marked by intolerance, hatred, and exclusion, have poisoned human beings'' relations with the world and each other. These need to be replaced by a new social morality and a heightened sense of humankind''s proper place in a dynamic universe.
