Captain Fathom

[first lines]

Narrator:
This is an underwater craft propelled by atomic power. Call her "The Explorer" and you know her purpose. Few have seen her, less have been on her, but many have either gained or suffered because of her. "The Explorer" is no ordinary submarine and her skipper is no ordinary man. His name is only known to a few - Captain Fathom.

Narrator:
Some think of him as an oceanographer, a brilliant engineer, a chemist of genius; while others regard him as the foremost hydrographer - but all agree Captain Fathom is first and foremost an adventurer!

[after attaching an explosive to an atomic bomb hidden on the ocean floor]

Captain Fathom:
I've set the mechanism to go off in an hour. Now I'm going to pull the pin. I hope the people who own this thing are insured.

[last lines]

Captain Fathom:
Bomb destroyed; mission completed. Take her up, Mr. Duncan.

Duncan:
Aye-aye, sir.
