Book Description
During the early stages of helicopter development, when helicopters were able to lift just slightly more than their own weight, the military services were eagerly seeking to obtain a variety of larger, more useful helicopters. The youthful helicopter industry expressed optimism, although at times unrealistic, in its ability to meet the military requirements. The development of the helicopter program within the Marine Corps was sparked by the foresight and imagination of the officers of the period. While early helicopters provided stepping stones for an orderly progression of the program, the slowness of the technical advances and the periods of financial austerity after World War II and Korea prevented the Marine Corps from developing the vertical envelopment concept as rapidly as desired. The program gained interest and momentum, however, as a result of the success of helicopters in Korea. As Lieutenant General Gerald C. Thomas stated: "Indeed, the helicopter gave clear evidence, from its first tactical employment, that a major advance in combat was at hand." This history, which traces the development of helicopters in the Marine Corps from 1946 to 1962, offers a tribute to the creative vision and planning of a handful of Marine officers who conceived of the vertical assault concept in amphibious operations at a time when suitable aircraft to make it work did not exist. The story of the subsequent struggle to procure and develop those aircraft, to refine a doctrine for their employment, and to familiarize the Marine Corps with their use is an interesting and vital part of modern Marine Corps history. The documentary basis for this monograph was primarily the official records of the Marine Corps and Navy Department, but considerable use was made of interviews and correspondence with key individuals involved in all phases of helicopter development.

Book Description
Learning to Think Spatially examines how spatial thinking might be incorporated into existing standards-based instruction across the school curriculum. Spatial thinking must be recognized as a fundamental part of Kâ€"12 education and as an integrator and a facilitator for problem solving across the curriculum. With advances in computing technologies and the increasing availability of geospatial data, spatial thinking will play a significant role in the information-based economy of the twenty-first century. Using appropriately designed support systems tailored to the Kâ€"12 context, spatial thinking can be taught formally to all students. A geographic information system (GIS) offers one example of a high-technology support system that can enable students and teachers to practice and apply spatial thinking in many areas of the curriculum.

Book Description
Here, for the first time in more than eighty years, is a detailed study of political Antimasonry on the national, state, and local levels, based on a survey of existing sources. The Antimasonic party, whose avowed goal was the destruction of the Masonic Lodge and other secret societies, was the first influential third party in the United States and introduced the device of the national presidential nominating convention in 1831. Vaughn focuses on the celebrated "Morgan Affair" of 1826, the alleged murder of a former Mason who exposed the fraternity's secrets. Thurlow Weed quickly transformed the crusading spirit aroused by this incident into an anti-Jackson party in New York. From New York, the party soon spread through the Northeast. To achieve success, the Antimasons in most states had to form alliances with the major parties, thus becoming the "flexible minority." After William Wirt's defeat by Andrew Jackson in the election of 1832, the party waned. Where it had been strong, Antimasonry became a reform-minded, anti-Clay faction of the new Whig party and helped to secure the presidential nominations of William Henry Harrison in 1836 and 1840. Vaughn concludes that although in many ways the Antimasonic Crusade was finally beneficial to the Masons, it was not until the 1850s that the fraternity regained its strength and influence.

Book Description
Conventional wisdom credits only entrepreneurs with the vision to create America's commercial airline industry and contends that it was not until Roosevelt's Civil Aeronautics Act of 1938 that federal airline regulation began. In Airlines and Air Mail, F. Robert van der Linden persuasively argues that Progressive republican policies of Herbert Hoover actually fostered the growth of American commercial aviation. Air mail contracts provided a critical indirect subsidy and a solid financial foundation for this nascent industry. Postmaster General Walter F. Brown used these contracts as a carrot and a stick to ensure that the industry developed in the public interest while guaranteeing the survival of the pioneering companies. Bureaucrats, entrepreneurs, and politicians of all stripes are thoughtfully portrayed in this thorough chronicle of one of America's most resounding successes, the commercial aviation industry.
