countdown. Ninety-nine people in a hundred would say that the countdown, counting backwards for rocket launches, was invented at Cape Canaveral. But the technique was conceived and the word coined by film director Fritz Lang in his science- fiction classic The Lady in the Moon, to give the rocket launch- ing in his realistic movie greater suspense. Persecuted by the Nazis, Lang fled Germany in the 1930s, but his countdown in- vention was used in early German rocket experiments leading to the V-2 and brought to America by German scientists who had worked on the early rockets. |
