FLYING SUB from VOYAGE TO THE BOTTOM OF THE SEA

Another Irwin Allen design, this manta-shaped hybrid ferried Admiral Nelson and Captain Crane to weekly encounters with assorted sea monsters, Cold War baddies, and pirate ghosts.

Ever cost-conscious, Irwin Allen scavenged whatever he could from previous productions -- which explains how hexagonal tiles from the Fantastic Voyage miniaturizer wound up inside the Flying Sub.
