In addition to improving the quality of existing products, the space program has been responsible for the development and improvement of new ones. The most important is the computer. To bring the endangered Apollo 13 home safely in 1970, a new flight plan had to be made taking account of an unbelievably complex combination of elements. The computer accomplished this task in seventy-two minutes, whereas a man or a woman working with pencil and paper would have taken more than a million years! If there had been no space program, it is doubtful that computers would now be so widely used in industry and government. More than 800, 000 people in the United States are now employed in jobs related to computers: it is a field in which some of the highest salaries are paid.
