Description: The series begins with the crash of an Earth spaceship that encountered a time warp while approaching Alpha Centauri on August 19, 1980. The spaceship is crewed by three astronauts, one of whom has died in the crash. The other two astronauts, Colonel Alan Virdon and Major Peter J. Burke, are unconscious but are rescued by an old man who carries them to an old bomb shelter. After the old man opens a book containing historical text and pictures of Earth circa 2500, the two astronauts are convinced that they are indeed on a future Earth.
