Douglas Adams's Starship Titanic

At the center of the galaxy, a vast, unknown civilization is preparing for an event of epic proportions: the launching of the greatest, most gorgeous, most technologically advanced Starship ever built - the Starship Titanic. The night before the launch, Leovinus, the galaxy's most renowned architect, is prowling around the ship having a last little look. With mounting alarm he begins to find things are not right: unfinished workmanship, cybersystems not working correctly, robots colliding with doors. How could this have happened? Something somewhere is terribly wrong. On the following day, in an artificial event staged for the media, the Starship Titanic will leave its construction dock under autopilot and, a few days later, make its way to the terminal to pick up passengers for its maiden voyage.
