    It was American Airlines Flight 77, rushing toward its target. In his Pentagon office, Army major David King was planning a precautionary evacuation when the room suddenly erupted in flames. Arlington firefighters Derek Spector, Brian Roache, and Ron Christman, among the first responders at the scene, were stunned by the sight that met them: a huge flaming hole gouged into the Pentagon’s side, a lawn strewn with smoking debris, and thousands of people, some badly injured, stumbling away from what would become one of the most daunting fires in American history. For more than twenty-four hours, Arlington firefighters and other crews faced some of the most dangerous and unusual circumstances imaginable. The size and structure of the Pentagon itself presented unique challenges, compelling firefighters to devise ingenious tactics and make bold decisions–until they finally extinguished the fire that threatened to cripple America’s military infrastructure just when it was needed most. Granted unprecedented access to the major players in the valiant response efforts, Patrick Creed and Rick Newman take us step-by-step through the harrowing minutes, hours, and days following the crash of American Airlines Flight 77 into the Pentagon’s western façade. Providing fascinating personal stories of the firefighters and rescuers, a broader view of how the U.S. national security command structure was held intact, and a sixteen-page insert of dramatic photographs, Firefight is a unique testament to the fortitude and resilience of America.

    Through the worst years of the Great Depression as many as five thousand laborers toiled twenty-four hours a day, seven days a week, to erect the huge structure that would harness the Colorado River and transform the American West.Construction of the giant dam was a triumph of human ingenuity, yet the full story of this monumental endeavor has never been told. Now, in an engrossing, fast-paced narrative, Joseph E. Stevens recounts the gripping saga of Hoover Dam. Drawing on a wealth of material, including manuscript collections, government documents, contemporary newspaper and magazine accounts, and personal interviews and correspondence with men and women who were involved with the construction, he brings the Hoover Dam adventure to life.Described here in dramatic detail are the deadly hazards the work crews faced as they hacked and blasted the dam’s foundation out of solid rock; the bitter political battles and violent labor unrest that threatened to shut the job down; the deprivation and grinding hardship endured by the workers’ families; the dam builders’ gambling, drinking, and whoring sprees in nearby Las Vegas; and the stirring triumphs and searing moments of terror as the massive concrete wedge rose inexorably from the canyon floor.Here, too, is an unforgettable cast of characters: Henry Kaiser, Warren Bechtel, and Harry Morrison, the ambitious, headstrong construction executives who gambled fortune and fame on the Hoover Dam contract; Frank Crowe, the brilliant, obsessed field engineer who relentlessly drove the work force to finish the dam two and a half years ahead of schedule; Sims Ely, the irascible, teetotaling eccentric who ruled Boulder City, the straightlaced company town created for the dam workers by the federal government; and many more men and women whose courage and sacrifice, greed and frailty, made the dam’s construction a great human, as well as technological, adventure.Hoover Dam is a compelling, irresistible account of an extraordinary American epic.

     After some meddling on the part of the Admiralty, many of the Academy's best are assigned to the oldest, smallest hulk in the Wargame, the unfortunately named corvette Chihuahua. Thanks to a genius engineer, an Army veteran loaned to the Navy for the war game, and an unconventional captain, they make a new discovery which turns her into the most valuable warship in the fleet: The first ever Shieldclad warship. The crew abruptly finds itself center stage in a real combat action, however, when Earth is attacked by an unknown foe, and a lone squadron of these once-mothballed ships is the Alliance's only hope to respond…

    Over the years their textbooks have introduced significant theoretical and pedagogical innovations in statics, dynamics, and mechanics of materials education. At the same time, their careful presentation of content, unmatched levels of accuracy, and attention to detail have made their texts the standard for excellence. The new Seventh Edition of Vector Mechanics for Engineers: Statics and Dynamics continues this tradition. The seventh edition is complemented by a media and supplement package that is targeted to address core course needs for both the student and the instructor.
