It's ficticious of course, but fantastic none the less.
It was launched from a bay in the belly of a submarine the "Seaview" and was used for research, rescue, and other such things. Now what would be really awesome, is if it could be made to work in a game like one of the Submarine sims that im fond of, and be able to not only fly it, but take it below the waves and explore the sea too.

The Author has ingeniously incorperated landing gear into this model, which the sub in the show did not have.
It's a work in progress, and he has many improvements in the works im sure.
