1,000-Year Voyage

The Dictator of Earth and his retinue have been banished into deep space on a 1,000-year voyage of no return to Alpha Centauri. The spacecraft has been completely automated to prevent tampering with the controls, and in any case, all of the original inhabitants of the craft will be long-dead by the time they reach their new home. Only their descendants will survive to propagate this brave new world. Or will they??? A grand space adventure.
