This book is a great read for anyone interested in aeronautics and astronautics. You can simply sit back and enjoy the American chronology of science and technology presented in it. When handling the book, be gentle to avoid further wear on the corners and edges. To maintain it, store it in a dry place away from direct sunlight to prevent the text block from tanning further. And always make sure your hands are clean before you pick it up to keep the interiors clean.
