Except in a few instances, since World War II no American soldier or sailor has been attacked by enemy air power. Conversely, no enemy soldier orsailor has acted in combat without being attacked or at least threatened by American air power. Aviators have brought the air weapon to bear against enemies while denying them the same prerogative. This is the legacy of the U.S. AirForce, purchased at great cost in both human and material resources.More often than not, aerial pioneers had to fight technological ignorance, bureaucratic opposition, public apathy, and disagreement over purpose.Every step in the evolution of air power led into new and untrodden territory, driven by humanitarian impulses; by the search for higher, faster, and farther flight; or by the conviction that the air way was the best way. Warriors have always coveted the high ground. If technology permitted them to reach it, men, women andan air force held and exploited it-from Thomas Selfridge, first among so many who gave that "last full measure of devotion"; to Women's Airforce Service Pilot Ann Baumgartner, who broke social barriers to become the first Americanwoman to pilot a jet; to Benjamin Davis, who broke racial barriers to become the first African American to command a flying group; to Chuck Yeager, a one-time non-commissioned flight officer who was the first to exceed the speed of sound; to John Levitow, who earned the Medal of Honor by throwing himself over a live flare to save his gunship crew; to John Warden, who began a revolution in air power thought and strategy that was put to spectacular use in the Gulf War.Industrialization has brought total war and air power has brought the means to overfly an enemy's defenses and attack its sources of power directly. Americans have perceived air power from the start as a more efficient means of waging war and as a symbol of the nation's commitment to technology to master challenges, minimize casualties, and defeat adversaries.

This series introduces the core areas of chemical science, covering important concepts in an easy, accessible style. Each title contains a number of experiments and demonstrations, approached through the process of problem, hypothesis, experiment and conclusion. All the books support the QCA schemes of work and contain: definitions of important terms and explanations of key concepts; formulae and word equations; and the periodic table with explanatory notes. This title explores the concepts of the states of matter.

From its beginnings in 1907 as the Aeronautical Division of U.S. Armys Signal Corps, which consisted of one officer and two enlisted men, the United States Air Force has grown to become the foremost aerial armed force in the world. Although they had to fly French and British planes as the fledgling army aeronautical bureaucracy failed to procure any combat-worthy American aircraft, which arguably did not exist, American aviators performed valiantly in World War I with intrepid pilots of the such as Eddie Rickenbacker and Frank Luke leading the way. Between the wars, all of aviation, commercial and military around the world grew by leaps and bounds as the numbers of aircraft in service and their capabilities tremendously increased. Although the Army Air Corps, as it was known at the time, was no better prepared for World War II than the rest of the army, it had developed a highly professional corps of experienced officers who would be able to take advantage of the latest American aircraft technology such as the B-17 Flying Fortress and the P-51 Mustang. With the end of the war and the creation of an independent armed force in 1947, the United States Air Force leapt into the jet age with such icons as the F-86 Sabre and the remarkable B-52 Stratofortress, which "soldiers" on today more than fifty years after going into service in 1955 and with the youngest of the 744 plane production run being forty years old, having been built in 1962.Air Force covers the entire history of the U.S. Air Force and its development from its beginnings early in the last century to becoming the worlds largest, most powerful, and most versatile air-combat force. Special attention is paid to the air forces recent, post-Vietnam history, and an entire chapter is devoted to Americas air force of the future.
