To bring the endangered Apollo 13 astronauts 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 take 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.
