The SS Marie Antoinette was a 51st century spaceship and the sister ship of the SS Madame de Pompadour. It crash-landed on the planet Earth some time before or during the Mesozoic Era.
Its crew of Clockwork Repair Droids survived until the Victorian era by scavenging any materials they required, including human body parts. The Marie Antoinette was incorporated into a restaurant above ground and could deploy a hot air balloon made from human skin through the roof of this building. (TV: Deep Breath)
