Storyline

Bill and Janu stumble into a lost underground world full of prehistoric animals and primitive cave men. Bill teaches the men some fundamentals which will make their lives easier, such as the wheel and simple irrigation. The existence of this unlikely habitat is explained when Bill finds a set of photographs, which reveal that the animals were stranded on Earth when a ship belonging to some inter-planetary cowboys was forced off-course.

Storyline

When their ship is damaged by an asteroid, Tommy and Brent are rescued by a ship decked out to resemble the old Earth legend of The Flying Dutchman. Its skipper, once Professor Cedric Hall, explains how an accident caused the loss of many lives, after which he went into self-exile, making his ship recognizable to all and never again to dock in an occupied port.
