"Within this book, many of the chapters draw on published arti- cles that I have written for magazines. I am glad to note their editors: At Air and Space, Linda Shiner and Patricia Trenner. At High Technol- ogy, Herb Brody, Peter Gwynne, and Paul Kinnucan. At Invention and Technology, an affiliate of American Heritage, Fred Allen, Fred Schwarz, and Richard Snow..."
