Commissioned on the occasion of its 75th Anniversary, here is the fascinating historical account of the American Institute of Aeronautics and Astronautics -- and its predecessor organizations, the American Rocket Society and The Institute of the Aeronautical Sciences -- and the significant contributions each has made to the evolution of flight. From the early struggles to create and distinguish aeronautics as a distinct profession, through the technological necessities brought on by two world wars, to the incredible advances spawned by the Space Age, this narrative covers it all in a highly readable, thoroughly researched way. Reading like an aeronautical and astronautical "who's who," it is also the amazing story of the organizations' founders, leaders and members -- visionary individuals and dedicated engineers advancing theories and technologies in a profession that has forever changed society and shaped everyday life as we know it.
