Another purchasable airship model mentioned by Louis, named in the system's usual mocking register.
When Donut balked at "Casket in the Sky," Louis clarified that it was the model name of the airplane type, not something he'd chosen, and that a whole catalog of models can be bought or built.

No further details about the model were given.
An alternative airship model, cited to prove the system names all its aircraft with contempt.
